Hello all....just replaced my very worn P265/70/16 Bridgestone Duelers with new P265/70/16 Yokohama Geolanders on my 2001 Tundra. Same load in the TT as always with same set up on WDH. This trip was the worst towing experience I have had ever. My Truck was swaying all over the highway while my TT remained stable. I bumped the psi to 40 going and then 48 coming back. Both rides were equally bad. Even a small SUV passing me on the highay was pushing and pulling me. On the ride home I even adjusted my wdh to put more weight on the front axle and still all over the place. I have done some research and questioning on FB pages related to towing and the majority thinks I should upgrade to LT tires. My TT weighs 5,200 loaded. I called my tire salesman and he agreed to let me swap the tires out. However he cannot get me the same size in an LT tire. He said I would have to either go from a 265/70/16 to a 265/75/16 or he can get me a 245/75/16. Ideally I want to stay with the same size because I cannot adjust my hitch any more. I am already at the very bottom hole on the shank. Will going from a 70 to a 75 require a hitch adjustment? He can get me a Yokohama in the LT which is the brand I have now. Is the Yokohama brand the issue? Will it feel better in the LT version? I am so confused about all of this. I do not want to tow with that feeling ever again. I towed fine for 2 years with my worn out P rated Bridgestone Duelers, what was the big difference? By the way I would have kept the bridgestones but we didn't pass state inspection with them. I thought for sure getting new tires would make the drive even better not worse. Thanks for any help!
