Hello,
For what it's worth, I love the look of the Ascent with the stock 20" wheels and don't plan to move to 18s. That being said, it is true there are more tire choices in the 18" diameter than 20" and they are cheaper. Sticking with the 20" diameter, I have been thinking of installing 255/50s instead of the 245/50s it comes with. However, it appears there or more tire choices in this size than the 245 size. The diameter difference is negliable (0.4"), but of slightly larger concern to me is the weight rating. Most tires of the 255/50 size are XL load rated - approximately 2200 lbs vs the 1800ish lbs of the 245s. In terms of load rating numbers, the 255s XLs are 109 and the 245s are 102. Should I expect this higher load rating to translate to a rougher ride or would it be offset by the slighty larger diameter? Should I expect any fitment issues on 255/50s on the stock 20" wheels and stock ride height of the Ascent?
Thanks!
