Tires I am talking here. About 2 weeks ago I rotated my tires on the Silverado. A few days after that we started to get a little shimmy/vibration at around 40-50 mph.
Drive train all checked out ok so I just figured one of the tires had gotten a flat spot when it was parked for 2 months this summer. The tire pressures were right on the 80lb mark each morning so I did not worry.
Today we were pulling the 5er north and I got a "tire pressure to high" warning on the display screen after we had gone about 30 miles down the freeway. I pulled over and verified it was not just the TPM sensor going bad. Then turned around and took the truck to Wal Mart. I figured it had to be the flat spot tire. I bought two new 265/75/16 tires for the rear and kept the old tires since they still had a lot of tread and looked just fine.
On closer inspection at home I found one of the tires had started to separate on the inside. Just to one side of the center of the tire a blister had started to form that went 2/3 of the way around the tire but was only about 1/2 of inch wide.
ANYWAY, The point I am trying to convey is that if your truck develops a vibration/shimmy coming from the rear end, it may be one bad tire getting hot.
