no its from tire wax and i see peter you have always a good word for everthing

I had a set of these i was going to run and at some point may still run them. They are a drag radial and shoudl be warmed up at the track. I would not run them on the street because they are going to wear pretty quick. I had a freind running these on his mustang and liked them alot.

I fixed your pics....your IMG tags were a disaster!
