@3 months every tire developed a sidewall bulge, I called & they said it should be fine. @36k 1 of the sidewalls split right down the bulge & blew out just before getting on the highway. Turns out Goodyear doesn’t know how to bond plies together & the radial bands themselves pulled apart. I also had a few other issues prior. You need to re-balance these every 10k because the density of the rubber isn’t consistent. They'll wear slightly faster on one side causing violent shake @highway speed until you re-balance them. The rubber showed signs of early rot. I'll never buy Goodyear again. The build quality is trash. I wouldn’t trust your family’s safety with Duratrac.
Mine balanced better than the stock KO2's. The KO2's took way more weights to balance and one of them had to be rebalanced at every rotation.
Duratracs are the only Goodyear tire I've had good luck with.
