Higher profile tires for 21 Greys

[Walter A]

Does anyone have an opinion about using higher profile tires on Tesla 21 " grey wheels. For example use 245-40-R21 instead of OEM 245-35-R21 or 265-40-R21 instead of OEM 265-35-R21?

Your outer rolling diameter will increase with the taller sidewall, therefore throwing off your speedometer reading. If you want to go taller, need to go narrower tread as well to keep the relative diameter as close as possible.

Sidewall height difference between 40 and 35 is really only about 1/2" so if you are thinking of better wheel protection for potholes, don't think 1/2" difference would make much difference.

Might drive the Tesla systems crazy too.

Consider wheel well clearance is very tight, especially fronts while turning.
I had wheel rubbing issues with the correct size when I first purchased winter tires.
