Not impressed with Goodyear in regard to being a strong tire. I have towed at highway speeds with them (TP boosted by 10 psi per a Goodyear bulletin) and never had a problem. However, I have changed a few due to sidewall cuts that happen when taking the trailer off-road and sidewalls hitting sharp rocks.
I would say that is expected, but on my Hummers that I take off-road on some extremely serious trails, I have never had a sidewall cut.
But I guess that is expected with trailer tires, they are not designed to do any type of off-roading where there could be sharp rocks.
So, I switched to Yokohama truck tires. But some serious research and calculations are needed prior to doing the switch and it may not be an option for most.
And that last sentence will cause a lot of controversy
, but I'm not alone in doing this. In fact, many of the off-road trailers shipped from the factory have A/T truck tires.
