Thanks for all this info guys! My M3P is due in a few weeks with the stock 18" Aeros which I will sell on eBay. I'm looking to buy 4 take-offs the Tesla OEM Sport 19"x8.5" wheels but am hoping to put a 245-45-19 for more sidewall comfort as I drive for hours at work. Do you think this size will fit and look ok? I'd like more sidewall to fill the wheel opening also but don't want it to look lame.
My other car has BFG G-Force Comp TA which are somewhat loud but sporty, comfortable and cheap. Thinking the BFG's might be good.
