I've switched over from run flats to non-run flat tires and went up a size, from 205/45 17 to 215/45 17. My new wheels are 1/2" wider than stock also. Will I still use the same tire pressure as indicated on the door frame for stock tires and wheels? If not, how do you calculate the correct tire pressure? I looked around the web for a tire pressure calculator or a chart and didn't see one.
