I have never had anything like this happen to me. I had a doctors apt. and took the bike after getting off 1 25 it felt almost like i had a flat tire this stuff had my tread covered about a half inch thick in areas. I got off at the next red light to see giant chunks of tar stuck to the back tire. I went to the apointment and came out with paper towel and tried to rip it off and it wasn't working very well. So I got sick of it and decided to do a little burnout which worked, but I had the same thing happen before getting on the freeway. It finally came off on the concrete, but it was very annoying anyone else have anything like this happen. It made the entire bike shake and almost caused me to lose it while leaning before I noticed something was wrong. If i get caught doing a tar removal burnout I do not think the bacon patrol will be very understanding either.
