Nota sureI have more pertinent info--I have had 16" GYs on my '05--they were basically running at rated weight. Changed out to 17.5" tires/wheels, put Michelins on. They made it couple of years, then had tread separations and the famous sidewall cracks. Yes, speed-rated at 62. Went on to Coopers and Sailuns, never a failure. Sailuns on when traded. Got a '15 RSSA with the GY G114s--2 tread separations and changed over to Coopers. They were running great when traded again. Would have to say--none of my tires have had a blowout, only tread separations. GYs are on every DRV from the factory, I think--therefore, more problems arise with them just because that is what they come with. GY and Michelin are not the end all in tires--many others just as good and less expensive: Cooper RM 170; Sailun S637; others. Also, should consider going to the 235 size instead of the 215 factory size--much higher weight capacity.
