The 62 MPH speed rating isn't a theory, it's what the manufacturer rates them at. Give the manufacturer a call, not a dealer, the main company representative. Of the dealers I called only one out of 4 had the speed rating available, the others just said they had no info on it even after checking their spec sheets. The cost ratio wasn't an issue as the price for Michelins was only $5 different, and was lower to boot from the supplier I used.

I chose not to get the Michelins because of the speed rating and the lack of confidence the rep expressed for warranty issues if the rating was exceeded. We often get over 70 on downhill runs on steep mountains. I also had experience with Goodyear's warranty response and was happy with the way they treated me on the trailer we had before the MS.
