In the old days I thought I was saving money by rotating my tires ever 30,000 miles. Ray, a friend of mine owns a front end, alignment shop. He told me the rear tires tend to bounce around on the road due to the light weight of the rear of the car. This causes tiny cups in time the tire can produce various sounds or a roar. Ray said, when i'm ready, to go buy michelins. He also told me they were the roundest tire of them all. This was in the late 70's. Ray rotated and balanced my tires ever 7500 miles back then.

I now live in southern new mexico. I found its convenient to go to walmart to get the tires rotated and balanced. I got their lifetime rotate & balance. I have them done ever 5000 miles, usually after I change the oil. The waiting is nice, having such a large store to shop in. I have talked to others that don't rotate till 9000 to 12000 miles.

Other than the OEM tires on some GM, Ford and Toyota cars I bought, I have went back with michelins. Popular michelin tires I know of is the hydroedge, pilot and the new Energy S8 tire. They also make a lower priced OEM type replacment tire.

The michelin Energy tire is being replaced with a slightly better in all categories, Energy S8 tire. A few weeks ago we test drove a TCH with those tires and thats the best steering ever. Could be the combo of the electric hybrid steering and those tires.

I always run 35 psi after the tires have cooled and are in the shade. The tires wears normally, no slick edges and it improves my gas mileage.

I did read the high mpg guys in this forum run 40 to 44 psi to get a slight edge for better gas mileage. I may go that route later depending on the mileage I get, once the engine is broke in.

Tirerack.com has some pages where it's easy to compare tires. Some show better than these.
