My mom and I both have 06 mazda5s. I was getting the rotational noise associated with uneven wear at around 20,000 miles. I had just moved and was going to a new Mazda dealership for my scheduled service and the guy said it looked as though the tires had never been rotated. He rotated them for me, fronts to rears, and said that if the noise came back or got worse, he could sell me new tires, but he couldn't do it in good conscience, then, because the amount of tread left (on the good sides) was decent. two oil changes later, the noise was getting worse, and he sold me a whole new set of tires. They're much less noisy, and I haven't had uneven wear troubles yet (been on about 6k miles).
My mom's 5 is up to about 28k miles and she is now getting the rotational noise... she's dealing with the same dealership I was, before I moved.
If you go for regular service at a mazda dealership, how often should they be rotated? Is it in the schedule of regular maintenance?
Has anyone gotten uneven wear on tires besides the stock Toyos?
