I replaced the Good Year 275/75 22.5 G670's that had rivering so bad they finally flat spotted. Good Year first said to rotate, balance and front end alignment which I did but got worse. Then they disavowed any knowledge of this "phenomenon". They said they would have a area rep. look at them, but he never showed up or even called. Put Michelin 275/80 22.5 XZA3+ LRH and am very pleased with better handling and way better ride. Oh by the way no more rivering either "imagine that".
