2002 Grand Am Choppy Tires

Is it possible to get choppy tires if you don't rotate your tires every 6,000 miles or is the choppiness caused by something else? I have Goodyear Eagle RS-A performance tires.

Thanks

RSA's are crappy overall.

Yes , if you drive with off camber or toe , unbalanced or balljoints/tierods busted can affect tire wear and create a choppy crappy pattern.

bad shocks can cause a wave appearance on the tread of the tires as well
