The OP later says on different threads that he has rubbing and that he’ll definitely go 245 next time: Tesla model 3 rims : TeslaModel3 I found the answer to my own question. The motor trend article about track mode says “10mm wider” than stock rather than saying 245 when talking about Tesla Engineering sportcup 2 setup. Made all my google searches not hit. I definitely don’t want the cup 2s for street use. Now I can happily sleep at night and buy the 245s.
