As others have said, the tires are working. Tires these days slough off a
lot of rubber, which creates those off-line marbles. Most of what you have
picked up is what was those marbles. Your hot tires will pick up anything
they roll over -- cigarette butts, gumwrappers, small animals. Try ending
your race sometime with an incident that leaves you in the grass and then
look at all that vegetation growing off the donuts.
If you drive cool-off laps strictly on the racing line, you will have less.
Most of it is off-line.
Next session, waggle the car back and forth for a lap and it will be mostly
gone. We used to do that to warm up the tires (we still do, actually). Now
we do it to clean off the tires too.
And at the risk of sounding like I am trying to sell product -- some may
remember I peddle Formula V Traction Treatment -- I have found the FVTT a
great help when you are home and your tires are cold and you really want to
get the pickup off. Treat the tires and after it has soaked in an hour or
so, most of the pickup comes off relatively easily with a gasket
scraper(emphasis on "relatively" -- on a scale of 1-10 it is a 4 instead of
a 9). Caution, it is a really messy job because you are working with tires
fresh with FVTT and you'll get carbon black from the tires all over you, so
wear something you don't care about and maybe rubber gloves. I've done it a
time or two. Came to the conclusion it was wasted effort.
