What is the largest or best tire size combination to be used with 20" Carrerra S wheels on a 2014 Base Boxster? I know i would be better off using 18" wheels for autocross but my budget will not allow this at the moment. I am as least planning on going up to a 245/35/20 on the front and 275/35/20 on the rear. I am also open to going even larger if nothing will rub. Thanks in advance!!

I've run 245 / 275 on my 2013 BS with no issues. Search at planet-9, some dedicated track cars are running up to 255 / 295.

That is the size i ordered Monday before the Michelin $150 rebate went away. I just went with what i knew would work without any issues since i did not get any replies.
