Probably had'm rotated(my rears were in great shape after 30k the fronts were screwed) make sure to get them balanced as well. I rotated mine(skipped the balance) to the front and it drove bad at points, did'nt mind to much because I knew I was going to get all new tires pretty soon.

With my new tires I got a pretty cool deal, free tire rotation for the life of the tires. I plan on them checking the balance on every rotation, if it costs extra...I don't mind...I learned a good lesson with my past set of tires and I plan to keep my Toyos for a while.
