This actually happened a couple of months ago, and I just noticed the damage this week - no air leaks or any problems with the tires visible on the outside. Will see if any damage inside the tire, when pulled for repair.Is this a case of the impact causing the tires to be squished enough for the wheels to take the impact? I am surprised the tires aren't damaged.
I don't think this is a problem specific to the i3. In my area there are at least five shops making a pretty good business out of just repairing bent and cracked alloy rims (bent steel rims usually just get replaced with new for cost reasons). So hitting pot-holes and curbs hard enough to damage wheels must be pretty common. Looking at posted reviews for the local wheel repair businesses, car owners list Mercedes, Lexus, Tesla, Jaguar, etc. where they have had their bent alloy wheels repaired.It seems tires/odd wheel size on i3 is not practical for consumers but only for BMW engineers.
Definitely something to check, though I hit the pot-hole ( at 40 mph) several months ago, and just notices the bent rims last week - no tire pressure issues, no vibration or noise. Was just checking under the rear of the car for the Rex oil drain plug location, and saw the bend on the inside of the rear rim. And am just assuming it was the pot-hole I hit that did the damage, the bent rims could have been this way when I bought the car as a lease-return.Fast enough to damage the rims, I'd seriously look at the tires...you might be driving on a set ready to blow out.
Here's one I appreciate the narrow tires because of their reduced aerodynamic drag and low rolling resistance that increase the range of our BEV and because the resulting narrower fenders do not impinge on interior space as much as wider tires would. With 19" wheels and tires, we haven't had a single flat tire in our 4.5 years of i3 ownership despite the poor condition of Honolulu streets and still have lots of tread left on the original tires. So for us, what's not to like?
