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 |

Is this on your street car or just an autox car? If dedicated autox car, I wouldn't even bother balancing them, much less worry about the slipping.

QUOTE(Brett W @ Apr 27 2009, 01:54 PM)  Is this on your street car or just an autox car? If dedicated autox car, I wouldn't even bother balancing them, much less worry about the slipping. Toyo Spec 911 race car, GTS class with PRC, SP911 class with PCA. No Street, no AX, just *big* track ... 3.0L with aftermarket FI. About ~270 HP at the rear wheels. 245 x 16 Toyo RA1 tires in the rear. (IMG:style_emoticons/default/shades.gif) Andy PS: I have no idea what lube or how much of it they used when they mounted the tires. I didn't stick around to watch them put them on, just picked 'em up later ... Attached thumbnail(s)
