ST tires

[Ray,IN]

Most tire charts I've viewed list the speed rating for all ST tires at 65 MPH. Could this be a contributing factor to so many of us having ST tire problems?

I attended a Goodyear seminar at the RV Rally in Daytona Beach, FL this past spring, and we were specifically told that the maximum load rating of their Marathon tires was only up to 65 mph, and the load rating would DECREASE by 10% for every MPH over 65.

Most ST or trailer tires are of the 13", 14" and 15" sizes. Once you get to larger RV's like big fifth wheels, a 16" wheel/tire combo is used. Once you get that large, LT or light truck tires are used. LT tires are the same tires that most of us use on our pickups. I have yet to see a ST type tire in a 16" size.

Well THAT explains what I had figured out my self. With my old trailer everytime I went over 65 I would need at least one new tire. I stayed under 65.
