I have a 2011 V6 (no special packages). I am about to order the Boss 338 wheels - 20X8.5 front and 20X10 rear. What is the widest possible tire that will fit on my car?
For the front, a 255/35/20 should be sufficient but you could go with a larger sidewall if you want (maybe 40 series). As for the rear, you could use a 295/35/20 but I would suggest going with a 275/35/20 as its diameter is within 1.5mm (.05 inches) of the stock size which means you won't have to worry about reprogramming your speedo
