Les Schwab, new tire out the door, $139.64 mounted on rim, 9/21/2015, ST225/75R-15, locked up brake on one tire causing flat spot, so replaced. Could have sold me any tire but according to tire dealer the Towmax was a good replacement.

Dealer manager said failures of tires they see from RV's are due to speed, too much weight and not keeping watch on PSI. My trailer is light at 5,500 Lb when attached to truck, 6,100 Lb sitting by itself, scale weights. 1,375 Lb per tire when trailer is attached to our truck, 2,540 is max weight for each tire, margin of safety is 1,165 Lb or 45%. Next Cougar up in size uses same tire, lower safety margin as trailer model weights go up.
