Both of my rear tires have flat spots on the inside of both tires. More than one. They are all around the inside. What causes this. Is my alignment off or my shocks gone? I have over 110000 miles on the original suspension and only about less than 2 years on the tires.

Thanks, Eric

 

How often do you rotate?

I would say on original suspension you need to replace just about everything now or within the next 15k miles. I have replaced everything over the past 15k miles chasing down tire wear and pulling, my last front tires lasted 5k miles before they were bald.

I would replace the trailing arm bushings or add the inserts. replace the rear control arms w/ something aftermarket and get a good alignment. If you don't want to replace anything then at a minimum you need an alignment and don't forget to rotate your tires.

 

Shocks are most likely gone. At that mileage I would consider replacing all 4.
