Tires Cupping Need Opinions
Hello everyone, TB '06. I'm having an ongoing issue with the front tires cupping on the insides. History: Purchased Destination A/t tires from Firestone, had alignment done upon installation. They do a front end check prior to alignment. Months later I notice the fronts cupping. Changed the struts. Still cupping. Bring it back and they check everything out again along with alignment. All in spec. Tech adjusted camber slightly out of spec to compensate for cupping. Still cupping. Bring it to a different, very reputable, mechanic. Called me back tonight and said there is nothing wrong with the front end at all.
I'll be getting an inspection done soon and know these tires will not pass due to cupping on the insides only. At least 1/2 tread on the rest of the tire if not more. I have no issues with getting new tires but don't want to put new tires on only to find out they are going to cup also. Could the problem be the tires themselves? Ideas?
