BMW i3 Wheels and Tires: What you need to know

You get a better view of just how tall and thin the tires on the i3 are without the body in place

Note: This was originally posted on February 17th, 2014. I have had so many people message me about tire and wheel size information that I thought it would be a good idea to repost it.

One of the more talked about features of the i3 is its tires. Not for decades has there been a car with such tall and narrow wheels and tires. Since the 70's, the trend has been for tires to get wider and wider, and that is especially true for performance cars since more rubber on the ground generally means better roadholding.

Performance is critical for any BMW

Then came along the i3. It's BMW's quirky-looking mega-city car, and the first electric car from the brand. With all the incredibly unique aspects of this vehicle, it's still the tires that catch most peoples attention when they first see it in person. They just aren't used to seeing such tall and thin tires on a car, let alone a BMW. Actually, they look like they would be better suited for a motorcycle, but that's just because we just aren't accustomed to seeing tires like this. Rest assured the BMW engineers have done their homework, and the tires do exactly whet they were designed to. They provide excellent grip while increasing the cars efficiency with lower aerodynamic drag.

BMW commissioned Bridgestone to make special tires just for the i3. Even though they carry the "Ecopia" name, they are different from any other tire that Bridgestone makes. Franco Annunziato, CEO and President of Bridgestone Europe said: “The BMW i3 is very much a car for the future. Developing a unique tire for this unique vehicle was therefore an enormously challenging but also rewarding experience. Energy efficiency is an important development criteria for all our tires at Bridgestone. However, it becomes an even more critical factor in an electric car. Which is why we have put all our knowhow, skill and passion into developing this unique tire. One that we are confident delivers the premium performance, safety and economy towards consumers who have come to expect it from both brands.” As for performance, since BMW wanted to use a narrow tire for efficiency but not sacrifice on performance, they needed to use a much taller tire than most would expect on a car of this size. By increasing the height, they were able to increase the contact patch so it is similar to the contact patch of a MINI Cooper, which is well known for its great handling. Talking about the i3's tires and their grip on the road, Ulrich Krantz, BMW's product manager for BMW i said: "It’s not rocket science. All that matters is the size of the contact patch. The 19-inch tires may be skinny, but their tall height generates the same contact patch as a low-section 16-inch MINI tire". 
 

1) Standard Mega 19" #427  2) Tera World 19" #428   3) Giga World 19" #429   4) Optional 20" Sport  #430

So with the question of performance behind us let's focus on the tire and wheel sizes and combinations. BMW doesn't make it easy here. The standard wheel on the base Mega World interior is a BMW i Star Spoke (Style 427) wheel that is 19" x 5" on the front and rear and they use the 155/70 R19 84Q Bridgestone Ecopia EP600 all season tires that were specifically designed for the i3. Here is where it starts to get tricky. If you get a BEV i3 with the standard Mega trim, the wheels and tires are the same size on the front & rear, but if you get any other interior trim (Giga or Tera Worlds) the rear wheels are slightly wider (19" x 5.5") and the tires are wider and lower profile (175/60 R19 86Q). Also, if you get the standard Mega World trim but get the range extender, you also get the wider wheels and tires on the rears. Then there are the optional 20" Double Spoke sport wheels. They are also staggered in size and use Bridgestone Ecopia EP500 summer tires, not all-seasons. Up front you get 20" x 5" wheels and 155/60 R20 80Q tires and in the back there are 20" x 5.5" wheels and 175/55 R20 85Q tires.

EP600's on left & winter tire on right

So the wheel and tire size is staggered in every instance except for a base i3 with Mega World trim and no range extender, right? Kinda. Everything above applies for the standard 19" Bridgestone Ecopia EP600 and 20" Ecopia EP500 tires but not if you want/need winter tires. There will be two different winter tires available (Blizzak LM500 & Blizzak NV, though I'm not sure they will both be available in the US). However they will only be available in 155/70 R19, so if you want the winter tires you'll be using the same size front and rear tire. Furthermore, if you order your i3 with the optional 20" Sport wheels ($1,300 option) and you live in an area that would necessitate winter tires, then you'll need to buy a set of 19" wheels also, since there are no 20" winter tires that will fit the 20" sport wheels. I have spoken to BMW product managers about this and was told bluntly that the 20" tires are summer tires, not all-seasons and they will not perform well in snow and ice. So if you were considering the 20" sport wheels for your i3 and you live in a cold weather area, understand you'll likely need to spend another $2,000 or so to get a set of winter tires & wheels, since you can't just buy the tires. If you have any of the three 19" wheels then all you need to do is buy the winter tires and you can swap them for the winter and put your Ecopia EP600's back on in the spring.

The 20" Sport #430 Wheels

One more thing. None of the tires are runflats, and the i3 does not have a spare tire. What you do get is a can of "Fix-a-Flat" tire sealant and compressed air, which if used properly should get you at least as far as your nearest BMW dealer which will likely be the only place that stocks there rare tire sizes. If not used properly it will blow up in your hand leaving you covered with the sticky goo meant to seal the hole and you'll be calling Roadside Assistance. Finally, if you are wondering how well the i3 does in the snow, below are a couple videos that were just posted on YouTube by a new i3 owner in Norway. I have also talked with a couple people that have driven the i3 in the snow and they have remarked about how well it has done, likely another benefit of the tall, thin tires that slice through the snow instead of rolling over it.

Snow chains are available for the 19" tires

BMW ///M i3: It's Coming - Soon!

A full range of official press photos of this semi-camouflaged Mi3 will be released a couple days before NAIAS in two weeks. This is the only one I was authorized to reveal.

About six months ago, Eric Loveday of InsideEVs.com wrote this article that predicted the BMW M performance division won't be making an M version of the upcoming BMW i3 or i8. I've known for a while now that that was not true, but the information I got from BMW was under embargo until now so I couldn't comment on it previously. I finally got a chance to look at a pre-production ///M i3 last week. The car I saw didn't have all the body work or the special wheels that the ///M i3 pictured above has since this one is being used for internal testing here at BMW's North American headquarters, but it did have all the performance upgrades and ///M badging.

I was lucky to be one of only a few people to get a sneak peak of the M i3 before its unveiling at NYIAS in two weeks.

Perhaps this was the intention all along, or maybe BMW changed their minds along the way, but both the upcoming i3 and i8 plug-ins from BMW i will get the "M" treatment. Back in August of last year I did a post about BMW offering a Sport Version to satisfy the desires of the performance minded i3 buyers and it turns out BMW was definitely listening. Honestly, I would have really been surprised if the i3 didn't have an ///M variant or at the very least, as I suggested, a special edition "Sport" i3.

One person posted this on Bimmerpost. Perhaps they were wishing for an ///M i3 also?

Recent articles have popped up around the web eluding to the fact that BMW was working on a "special edition" i3 and that it would have a more aggressive appearance, but many assumed that would be reserved for the i3 coupe which is expected to launch about a year after the 5 door hatchback i3 that is available now. That's may be so, but I have confirmed the ///M i3 will indeed be a modified version of the current i3 offering, and it will indeed be available soon after the initial US i3 launch. If the i3 concept coupe does make it to production, it would seem likely to get the same ///M treatment as the 5 door hatchback is.

I knew all along that if BMW really wanted their customer base to welcome the i3 and accept it as a true BMW then they would have to offer a performance version, just like they do with their other models. Performance is in BMW's DNA, it's what distinguishes a BMW from the other premium brands. To not make a performance version of the i3 would seem to be a mistake in my opinion. However I didn't expect it to come so quickly. I figured the ///M i3 would be launched sometime in 2016 to invigorate interest once the initial excitement over the i3 began to wane.

TopSpeed (www.topspeed.com) had their go at what they think the ///M i3 will look like

Loveday wrote, "We suspect that BMW will make available several performance-enhancing products for both the i3 and i8 in the near future, but both an i3M (Mi3) and an i8M (Mi8) seem to be no-goes." That's certainly understandable since BMW had said on more than one occasion that they will not be tapping the M performance division to tweak the i3 & i8.  So what do I think changed their minds? My guess is surveys; it's that simple. Last September I received an email survey from BMW i asking me about 50 questions regarding my interest in the i3. I'm not sure if I was included in the survey because I drive an ActiveE or just because I was signed up on the main BMW website for i3 information, but the survey focused on what options I would pay extra for. Almost all of the questions centered around paying for more range and paying for more performance, with one of the questions specifically asking if I would pay and additional $8,000  for an ///M version of the i3.

Fortunately the majority of the respondents must have answered as I did, saying yes we would be willing to pay extra for both range and performance. Yes, I know the i3 is focused on sustainable personal transportation for an evolving world, but hell, there's always the weekends, and i3 owners will want to autocross their cars just like 3-Series owners do. That's part of the BMW heritage, and part of why people gravitate to the brand.

TopSpeed's ///M i3 guess shown in coupe' form

Over the two weeks we should be getting all the details for the ///M i3 & ///M i8 models. The New York Auto Show opens on April 15th and both ///M cars will make their world premiers there. This will coincide with another special announcement regarding never-before released information about DC Fast charging for the i3, so if you are an i3 fan, head to the NYIAS this year. The Press preview days are April 16 & 17th, with the show opening up to the public on Friday the 18th and running until Sunday, April 27th.

The ///M i3 wheels will be a modified version of the optional 20" wheels available on the i8

Opening ceremonies of NYIAS will include Mayor de Blasio declaring the show officially open and that will take place at the BMW exhibit, likely next to the ///M i3 and ///M i8. This all but guarantees that pictures of the new performance-orientated plug-ins will be plastered in every newspaper in the NY metropolitan area. Unless BMW strategically places their gas offerings there which would be very disappointing.

Little is actually known about the spec's of the ///M i8, but I do have some of the details on the ///M i3. Besides a more aggressive exterior styling, including a new front grill and spoiler, monochromatic paint (Yes, the black hood and rear diffusers will be painted the color of the car) a larger rear spoiler and fender flares. The standard wheels on the ///M i3 will be the 20" Sport wheels that are currently available on the i3 (the 19" wheels aren't available on the ///M i3). However there will also be a wider wheel offering which puts a 20" x 6.5" wheel on the car with 245/40/R20 Brigestone Potenza S001 Tires. The wheels look very similar to the optional 20" BMW i8 wheels but they appear to be painted black in the press photo I obtained. The upgrade tire size is nearly perfect in diameter and the speedometer will not be affected at all. I suspect this will dramatically improve the handling, but it will certainly come with a price. I'd expect this tire and wheel combo to likely be about a $2,000 option, but for the performance-minded, it will likely be worth it!

Specification-wise all I know is that BMW is indeed using the same motor that the base i3 uses, it's just been modified to increase power output by about 25%. If that holds true, figure on about 210 horsepower and 230 lb-ft of torque. I was told the goal was to get the 0-60 times in the mid 5 second range and with that kind of added power I believe it is definitely within reach since the stock i3 BEV does it in about 7 seconds with 25% to 30% less power. The suspension will obviously be improved for performance and the interior will likely get the usual smattering of ///M badging and special seats which offer more support.

______________________________________________________________________

Now for the most intriguing part of this. The i3 has been designed around the philosophy of weight savings whenever possible. Many of these features will add weight which reduces efficiency. Plus, the more powerful drivetrain will likely use more energy than the stock set-up does. If someone were to drive the car hard (like it should be driven) then the range may only be 40 or 50 miles, and that's just not enough. So I asked if the ///M i3 would be available with the range extender, and was told definitely not; it will only be available in BEV form. Pressing further about the likely limited range of what will be a very expensive 40 mile electric car he replied, "The ///M i3 will have a greater electric range then the standard i3. It will also charge faster and offer technology unavailable in any other electric vehicle on the market." Now this is indeed getting interesting. There are really only two possibilities here that make any sense. It either has a larger battery pack, perhaps utilizing the space where the range extender goes, or BMW is using the higher density batteries that they have been testing in MINI-E mules for a couple years now. These cells are reported to have about a 30% greater energy density than the stock i3 batteries that come from Samsung have, so that would seem to work here.

I wish I could say I've had the opportunity to test drive it, but I didn't. I was only allowed a brief in person look at the one pictured above in Arravani grey which was at BMW NA's headquarters undergoing internal testing and give the BMW Press photo of the semi-camouflaged one on the track. Even without driving it or knowing what it's going to cost, I decided to cancel my Electronaut Edition i3 and place my order for an ///M i3. They aren't officially available yet so please don't call your dealer and ask to reserve one, that won't be possible until after the New York Auto Show. The ///M i3 & ///M i8 will also be available in "unique colors specific to the M division," I'm hoping Melbourne Red is one of them ;)

4/2/14 EDIT: As many of you figured out, this was an April Fools Post yesterday and I want future readers to realize that. If you take a look at the first letters of each paragraph that are in bold blue text you can see that spell "April fools", I'm surprised nobody commented on that here. I hope you enjoyed it and what I really hope for is a real ///M i3 form BMW sometime in the future!

US i3 Orders Limited to Special "Launch Edition" Package For First Three Months

You want one of the first i3's in the US? You'll be getting the full leather Tera World interior as seen above and every option available besides the 20" wheels then. Welcome to the "Launch Edition i3"

Just yesterday, BMW i dealers received a bulletin that informed them they can officially begin to process customer orders and place them in the pipeline. Many customers have already left deposits at their local BMW dealerships even though it wasn't an official order yet, with the hope of being one of the first people to take delivery of this revolutionary vehicle. However they didn't have an official order place in the system, that was just to have a place in line reserved for them and to make sure they got one of the few allotted cars their dealer would get for 2014. So now that these reservations can be turned into official orders, everyone must be really happy, right?

Not so fast. In a move that will most certainly anger many of the enthusiastic people waiting patiently for their i3, BMW informed the dealers that the initial first three months of US i3 production will be restricted to a special "Launch Edition" i3. The Launch Edition i3 has the top of the line interior Tera World and every option available on the car besides the 20" Sport Wheels which you can add if you would like. (Options include: Metallic paint, Parking Package, Technology and Drivers Assist Package, DC Quick Charge Option, Heated Seats and the Harman Kardon Premium sound system). The only choice the customer gets is whether or not they want the range extender, the exterior paint color and if they want the 20" Sport wheels. So unless the people waiting in like with deposits are willing to take a fully loaded Launch Edition i3, they will have to wait an additional three months for production of the custom ordered i3's to begin. The Launch Edition i3 production will run from March to May so custom ordered i3 production will not begin until June.

As expected this isn't sitting well with a lot of folks who have had deposits and reservations for many months now. I've had over a dozen people reach out to me today to confirm whether or not this was true after being notified by their dealer. Some thought the dealer was just trying to jack up the price of their car by making them get options they didn't want and were seeking clarification from me. I wish I could tell them it wasn't the truth, but this is how it's being done. The unfortunate thing is many people have expiring leases and planned to make due for a few weeks until their i3 came in but now the gap is more like 3 or 4 months and they don't know what to do. Should they bite the bullet and get an additional ~$4,000 of options they didn't necessarily want or wait till July for the i3 spec'd the way they ordered?

Here is the cost breakdown of the Launch Edition i3:

Base:141A(BEV): $41,350.00
Color:B81: $550.00
Tera world:ZTW: $2700.00
Parking Package:ZPK: $1000.00
Tech+Driving Assist:ZTD: $2500.00
Heated Front Seats:494: $350.00
DC Fast Charging:4U7: $700.00
Harman/Kardon:674: $800.00
Destination: $925.00

Total: $50,875.

If you want the range extender just add $3,850, so a Launch Edition i3 REx will set you back $54,725.


The only exception to this is ordering process is for the current ActiveE drivers like me. As a "thank you" for participating the the ActiveE trial lease program, BMW is allowing us to order our cars "a la carte" in addition to giving us the heated seats and DC quick charge options for free. BMW is also creating some unique features that only our cars will have like interior, exterior and door sill badging, embroidered front trunk liner and BMW i floor mats. Plus we get priority ordering and the first batch of i3's that come to the US will include our cars and we should begin receiving them the end of April. BMW is calling our cars the "Electronaut Edition i3" and these only be purchased by current ActiveE drivers. The ironic thing is, I ordered my i3 REx with the Tera World interior and every option available including the 20" sport wheels. So even though I had the freedom to build my car the way I wanted to that the other early i3 buyers won't have, I'm still getting the car loaded just like the Launch Edition anyway.

I'm sure this will elicit some interesting comments below.

The BMW i3's "Black Hand"

The i3 in Laurel Gray with BMW i Blue accent. Even though it's not quite as black in person as it looks in this picture, I like how it minimizes the two tone color scheme. I plan to order my i3 in this color scheme, with the 20" sport wheels as pictured and apply a dark tint to the rear windows. 

I get emails from readers here almost on a daily basis, and now that we are approaching the US launch the amount of correspondence I receive has been dramatically increasing. Quite often my blog posts are a reaction to something someone asked me. I figure if someone out there was curious enough about the topic to email me, then others probably are as well. I've had people ask me about this in the past, however yesterday and today I have had three people ask me if there was any way to special order a monochrome i3, with the hood, roof and accents all painted the color that the rest of the body panels are, instead of black.

The "Black Hand" extends to the side mirrors

Sorry, but the answer is no. If you want your i3 to be all the same color, you'll have to paint it or get it wrapped after you've bought it. The only other way around it is to consider getting it in Laurel Gray (Laurus Gray in Europe). Laurel Gray is a dark metallic gray, and while it isn't black, it's close enough to give your i3 the monochrome look you desire. I like this color a lot and will likely order my i3 with it.

Everything is black besides the bumper

The back of the car is particularly interesting because everything is black except the rear bumper which kind of gives the appearance that there is another car inside the i3 that is trying to get out! The New York Times Wheels Blog recently did a story on why BMW chose to use the black hood, roof and accents on all i3's regardless of the main color of the car. Evidently it was to "lighten" the appearance of an otherwise "chunky" small car.  Here is an excerpt from the NY Times story:


"In designing the i3 electric car, BMW engineers were tasked with reducing weight to compensate for heavy batteries. They used a combination of carbon-fiber reinforced plastic and aluminum, and the company mounted the passenger compartment atop the batteries. That approach made for a shorter vehicle with a lower center of gravity, but it also gave it a chunky profile. So designers set out to lighten the tall, bulky “monoform,” said Adrian van Hooydonk, BMW Group’s design director.

“We wanted to remove visual weight from the car,” he said. That meant using all sorts of techniques and tricks to break up the apparent mass of he car, he explained in an interview last week.

Mr. Van Hooydonk, Richard Kim and Benoit Jacob worked on designing the i3 for five years. The name they chose to describe the technique used to lighten the bulk of the car’s outline was the black hand, said Mr. van Hooydonk.

“The hood, as you see, is black, and the same material runs over the roof and to the back,” he explained. “This helps us divide up the volume.”

The i3 in white. We call this the "Panda Version" over on the i3 Facebook group

Solar Orange has been well received

The i3 Andesite Silver

What are your thoughts on the "black hand?"  Do you think it does what BMW had hoped it would, or would you rather your i3 painted all one color? Does anybody out there plan to paint their hood the same color of the car? How about a wrap? Lets discuss in the comments:
