That is all true, but in my experience a lap or two on track clears the tires so would that not be the easiest thing? I can understand pulling rubber from the inside of the wheel.

I have NEVER seen any one picking rubber off their tires. Is the rubber build up causing a problem.

I would not balance the tire with all that crap on it. If the tire came already mounted to the wheel I'd just drive it. All that crap should come off pretty quckly and then it should be fine. You could make the balance worse if you rebalance with crap on there and then it comes off at 2-3 laps on the track.
If you have tire service at the track you can always run a session and it the tire vibrates too much have them balance at the track.

Take it to a race shop that deals with tires. Most racing tire shops have the ability to shave tires. Just ask them to clean up the tire before they balance it. A good shop would do it without you even asking in the first place.

I get my tires shaved (RA-1) and my guy won't shave tires that have been run. It is very easy to damage the cutting blades from imbedded rocks and such. I think this is par for course on shaving.

Yep a little on-track warm-up with some side-to-side swerving should take care of the problem. In the future try and stay on the clean parts of the track and paddock on cool-down.
PS unless you're really sure about the tires pedigrees I'd put fresh rubber on and get 'em balanced.

. But it was an honest question, what does it matter? Are you the type of person that details their car inbetween sessions? And yes, I have seen people do that.
