correct size is 255/50/20 for the supercharged... Anyone running 255/55/20? Any rubbing or other issues going to a slightly higher aspect ratio?

TIA

Summer times I am running 275/50/20 winter times 275/40/20
My forum mate runs 285/60/20 without any issue.

Overall, the difference between a 50% and 55% aspect is about 1" or 25mm so the additional 1/2" or 12.5mm of wheel/tire filling up the wheel well would not be critical in regular driving. Of course, your rolling circumference will increase by about 3" or 75mm per wheel revolution, which will affect accuracy of speedometer and odometer readings.
