Destroyed two expensive tires (front and back Pass. side) last year. One ended up with a huge bubble in the sidewall, the rear one was cut/torn in the sidewall. And they are not cheap tires, top of the line Goodyears. Potthole was hidden in the shade on a sunny day, never saw it until after I hit it, turned around and drove back to see what I hit! Now it is back with a vengence and getting worse. Penn will not pay for repairs but they must know by now this is a continuing problem.
