I'm running 255 front and 285 back on stock wheels, no problems.I am running 275/35/19 on the back. There is some room left... Might be able to fit a 285.
I did. Did not notice much of a difference, if anything, with either of those.I'm also considering 245/35/19 & 275/30/19, but how would the ride quality and gas mileage be?
