I am about to purchase new tires and had a question for those who went with the stock size Michelin PS NON Run Flat tire. Looking at the specs for the non run flat, it appears the tread width is almost an inch thinner than the Run Flat (ZP) version. Once installed, does the tire look thinner, more of a ballooning affect, etc.?
Also, my next thought was to step up my size in the non run flat to make up for the thinner tread width, (this is where they get really expensive) and fill in the wheel well a little better. 255 on front and 295/305 on the rear. I have read several threads on the upsizing decision just curious if this was preferred over going with the stock size non run flat.
