Your new. A lot of guys would hammer you for not searching for the answer. It's in the threads. I don't feel like being a dick. Well maybe a little, but I'll be nice. I've run 275/40R19 on 19x9 wheels one all four corners. They had 45mm offset.
I believe I've seen someone run those sizes on a '11-'12 car. Check out the slammed on 18's, and 19's threads. There is a black car in one that has either 18 or 19 in RTR type wheels with 275 tires on all four corners.
