He said the tire looked like it was wobbling but on the inside, and sure enough it was separating on the inside wall.
So glad he noticed and took the time to flag me down.
When it was taken off the rim it looked like it had a huge balloon on the inside of the tire. It was the famous tow max (blow max) I new they were junk when I bought the rig and had planned on replacing soon. Had only 1500 miles on them. Always maintained before and after each trip.
Just goes to show you that new doesn't mean good no matter what the dealer may tell you! And I think they don't install the correct load range tire at the factory when you consider that the majority of the weight is on one side.
Need to get individual weights to see for sure. I was fortunate enough to have 110 psi rims so I didn't have to upgrade the rims.
