Hello, if anyone wants to replace their stock Michelin Primacy MXM4 tires with summer performance tires, I can confirm that it works fine to get a slightly wider and taller tire, I got Michelin Pilot Sport 4S tires installed at Costco. I have the aero wheels with aero covers removed, I'm in Los Angeles.
Stock tire from Tesla factory : size is 235/45/18
New tire size I got installed : 245/45/18
Compared to the stock tire size my Pilot 4S are a bit wider, it has more sidewall, slightly more diameter too. I'm just a regular driver who doesn't race but here is my review:
Noise and ride comfort: I didn't notice any difference compared to stock tires.
Grip: MUCH better compared to stock. After break in of a few hundred miles was done, I punished these tires on a wild ride from Burbank to Wrightwood through the twisty mountain roads on Highway 2 (Angeles Crest highway) last weekend and had a REALLY good time. I can drive with more confidence now. I can accelerate during the middle of a turn without any loss of grip or wheel spinning now.
Braking distance: I didn't test anything but supposedly the car is safer because my braking distance is much better with these tires.
I'm not sure how these would have been different if I bought the standard 235/45/18 size of the same tire. I probably have some slight loss of range with this bigger tire but I haven't noticed anything. Also I'll have to replace them sooner compared to stock. Here's an image of TireRack size compare tool. Hope this helps.
