These are the E rated Maxxis tires. Air infiltrated between the belts and the tread. Lucky I caught these prior to blowing out on the road.

Did you report the failure to NHTSA on their complaint form? Without numbers action to improve quality and fitment questions of tires on RVs will not improve.

This is not to say that Bambis don't occasion tire failures due to overloading, underinflation, old-age, lack of regular inspection, and other owner-induced problems.
The stress you are talking about have a specific name. Interply Shear.

If you Google "Interply SHear tire" you can learn more.
This is real engineering. Something that seems to be lacking in the RV industry.

I'm sure it has to do with weight, GVW, and tire size.

Until earlier this year when under pressure from US Government ST tires had speed limit of 65 mph. Some ST tires are now rated for 75 mph. Only tires with Speed symbol or specific words molded on tire sidewall are so rated.
According to the major tire companies, you know the ones with real R&D departments and understanding of tire usage in the US also limit speed to 75 in RV application no matter what the individual tire rating is.

The point is moot.
I won't be buying any more ST tires.

Unfortunately I didn't think about this aspect. Since this was my second set of ST tires with belt slippage in roughly the same period of use, I attributed it to the fact that expecting a full three years of life in my specific application was not reasonable for an ST tire. Note that I said "my specific application", since I know others get much better life. On the other hand those folks aren't pulling trailers that sit on a tandem axle and weigh between 8,600-9,100 lbs.

IMO even ST tires should not have this type of failure in 4-5 years.

Hercules

I plan to get a set of Hercules tires when the Goodyears time is up.
They make 15 inch tires in Load range ' D' and ' E ' . I have owned them before and never had an issue with them on my previous travel trailer over a three year span.

A friend of mine recommended Hercules to me as he had them on his Horse trailer. 36 month warranty.
They are hard to find. check their website out , it has a chart on load ratings. http://www.herculestire.com/tire-gal...ial/specialty/
If you don't run that ' solid white line' you lessen your risk on picking something up in a tire.
Have a good one
