I always mark the race tires right where the valve stem is so i don't have to look for the stem when i'm in a hurry.
We put a new set of tires on the 911 one week ago at Tunderhill and this weekend i noticed that the markings had moved several inches in relationship to the valve stem. So i marked the stem location again with a small dot and sure enough, after the first run session, the tires had moved again by several inches. This only seems to happen in the rear, i'm guessing under hard acceleration when the tires are cold (first session in the morning). Is this something that needs to be addressed or should i not worry about it? (IMG:style_emoticons/default/confused24.gif) Andy |

(IMG:style_emoticons/default/confused24.gif) Andy Andy, It will change/throw off the balance--the bigger the movement, the greater the change . . . . What did they use for a lubricant when they installed the new tires onto the rims? Some of the shops here had been using armor-all or other sil-based stuff that doesn't evaporate, and we'd see the tires rotate around the rim (usually on the front end--i guess due to FWD and braking forces).
