Michelin Pilot Sport 4S. I got a flat and plugged it at a gas station. Used their air but the barometer was wrong. Read 30 when I check with mine it was 70…. Ambient temp was 70F. The tire also sat totally flat for 5 mins while I bought the plug kit. Did I permanently damage the tire from grossly over inflating it or letting it sit on the sidewall (non run flat)? Max rating labeled on the side of the tire is 50psi…
