The new high-speed asphalt here proved troublesome in June, but this time Goodyear’s new tires are working well so far, Goodyear’s Rick Heinrich says. New asphalt is typically a low-wear situation, which can create heat issues, which is what Goodyear is trying to mitigate this time. #56-Martin Truex Jr., though, says there was little grip on the track for most of the afternoon practice session. And Goodyear, at NASCAR’s request, has released all the race day 400 tires early, so teams can scuff them in Saturday morning if they wish. Scuffing generally hardens a tire, making it more resistant to blistering.(MikeMulhern.net)(8-18-2012)
