I have been running MT ET Street Radials for years. But last year I raced them a lot and heated them a lot. Now they are so sticky driving on the street that they pick up stones and everything else. In the past after just a little street driving they would like glaze over and not be to bad. Now after driving them at least 20 miles they are almost as sticky as just leaving the burnout box.
Is there any trick to getting them to glaze over quicker or harden the top layer up? I don't want to destroy my car with stones.
