Default Re: Tires - suggestions please.

Whatever tires you get, make sure the shop that installs and balances them has a HUNTER Balancing machine with ROAD FORCE analysis capabilities. This machine determines the roundness of each tire as well as the roundness of the wheel. Should there be a low spot or a high spot in either ( or both) the machine will recommend how to turn the tire onto the wheel so that the high spot of the tire will math the low spot of the wheel or whatever the situation is. That way, it will make the tire/wheel combination as smooth as possible.

Should the tire on the wheel have a 25lbs or higher road force number, you should get another tire as it is out of round and will always shimmy and shake as you drive.

Shops that dont use that machine will be reluctant to replace a tire even if you complain about them being unbalanced.

I, personally, bought 2 sets of tires last year ( on different cars ) and in each case it took 6 tires to get 4 round ones.

Lucky for me, the installer was very sharp and is reputable. I bought the tires from TIRERACK and they paid for the new tires and the shipping back of the bad tires and the new ones to replace them.

Good luck

Incidentally, one of our distinguished TS member here on this forum is an engineer who happens to have worked for the HUNTER company. He has a wonderful and detailed explanation of the "road force" situation with tires. I recommend you do a search on that subject and gather relevant information.
