Press Release on new Bridgestones for the i3

Thu Jun 07, 2018 8:48 am

Another Forum site is reporting a BMW press release about new Bridgestone tires for the i3 and i3S. Are these the ones we already knew about for the i3S? If so, the presser seems to be saying that these will also be fitted to the normal i3.

Looks like the tier was launched early and now we have the press release . Talk about delay
But if the new ones can be fit to the older i3 , then is it possible to have all 4 tires in Rex as same ?

For Rex , while the EV range is not as important, the rear ones wear out early, and cannot be swapped with front
In my opinion , BMW re invented the wheel , but forgot about tire rotation.

People that have (mistakenly) installed the wider rear tire on the front quickly found out that it doesn't work...quickly ruined the tire while it rubbed on things. So, at least without maybe a spacer to give it a bit more space, and then, may end up illegal or rub on the fender, too, no, you can't get the wider wheel/tire on the front of a stock i3. The i3s is designed to handle wider tires and wheels on the front.

Many BMW models have staggered tires/wheels, and the rears won't fit on the front. This isn't unusual on performance cars. I think part of the reason the i3 was built to enable larger tires on the rear was to help accommodate the extra 300+ pounds of the REx...using them on the BEV was a side benefit. The base models and winter tire sets all are square using the smaller front wheels/tires.

So you would see no problem with fitting the "fronts" of new tire sizes (with wheels) all-around on an older i3?

Checking with TireRack - it looks like the 195 mm wide for the i3s rear only come in 20 inch wheel size - Ecopia EP500. So, if one wants to upgrade older i3 would have to use 20" wheels and spacers. The specs don't give the rim width range for the 195's but I'm guessing they would be OK on the standard 20" wheels. The Ecopia EP600 which is for the 19" wheels has 175 mm as widest option so no wider upgrade there for now.

2014-2016 i3 BEV's with 427 wheels (standard on North American Mega World) had the same size wheels and tires front and rear (not sure about the slightly heavier 2017-2018 models). However, all other i3's have had wider wheels and tires on the rear.

I would have preferred to be able to rotate tires in the normal fashion, but not enough to fit narrower wheels and tires on the rear of our 2014 BEV. The rear tires tend to wear faster than the front tires as is, so installing narrower tires on the rear would likely decrease rear tire life. The additional weight of the REx concentrated over the rear wheels might result in the load supported by the narrower rear tires exceeding their load rating when an i3 is carrying its maximum load.
