I have a 2012 mustang gt lowerd about 1". I just bought some vossen cv7 20x9 and 20x10.5. I want the invo tires. Nitto site says a 315 will fit on a 10.5" wheel or should I run a 295? I am looking for best traction. Thanks for you help.
The 315/35-20 tire size is going to be really aggressive with those rear wheels. You would need to do some fender modifications (pull the fenders) to avoid tire rub. The max tire size I suggest for the rear is 295/35-20. This rear size will pair well with 275/35-20's in the front.
