We bought the Mopar extended warranties on the last 4 vehicles we owned. I've had wheel bearings, intake manifold, radiator, rear hatch motor, starter, and a few other things replaced under the warranties. $100 deductible. Can't buy the parts for that price. As far as the tires, they are not covered. However, I have bought several tires at Discount Tire over the years and they patched a hole the wife had in her tire once. It was the original tire and not bought from them. They did it at no cost.
