I was talking to my buddy and he stated miss mounted and dry mounted tires on alot of the new vehicles including Jeeps is getting common. Another thing he has seen is suv units coming with a higher ply tire from the factory. For eg, a 10 ply tire requires very high air pressure 60 -80 psi)for ride and balance, and when you run them at 35 lbs you get what they call a lope, like riding in a grader. MTR tires without the kevlar where bad and in some occasions ran better with less vibration and shimmy at 25-27 psi, as it kind of counteracted the problem. He had a customer that did this and was surprised at the results. As the Jeeps are light this is possible, due to the fact that they don't go 90 mph and heat may not be a factor, and could still achieve reasonable wear.
I find if you got tire issues, talk to a qualified tire guy, as most service persons at a dealership would not be up to speed on this unfortunately. Should they be yes, but most just don't know.
By eg, my buddy has been with goodyear for over 20 years, and seen alot of weird stuff.
At the cost of replacement tires, with excessive wear and issues, one cannot afford to run long without correction. Even if you are out of pocket a few dollars. Some shops may even help you out for minimal dollars if they believe you and your friends will consider them when making your next tire purchase.
