All,
I realize this topic has been covered in the past, introducing it again hoping for new insights. Newish tires on my ‘94 Explorer are cupping badly with roughly 10,000 miles on them that the truck is almost undrivable between 64 and 76 miles an hour, with shaking noticeable at lower speeds, less so above 76. You can actually feel the variance in tread block height if you run your hand over a couple of the tires, worse on the right side. The X has about 78k miles, the suspension and various driveline components have been checked by two shops and indicated as being fine. I did have the radius arm bushings replaced when the tires were installed with, I believe, Moog parts as the shop which I trust fully felt these were worn and needed to be replaced at that time. Bilstein shocks at all four corners are also new. I’ve had the tires rotated three times since being installed. Tires are General Grabber A/T X LT235/75-15 on stock wheels which I've had checked for round and balance/true as well as having the tires rebalanced a couple of times. I went with the LT-sized Generals as I wanted “three peak” snow rating versus all-season m+s and these had great reviews and pricing. There were no “P” sized tires with the snow rating at the time in the correct size but several do exist today.
As mentioned, I’ve researched and read many of the prior posts on cupping and I am hoping there are new suggestions. any thoughts would be appreciated.
Thanks
Steve
