After reading all the posts on tires,it reminded me of the days when it was all about the longest burnouts.In 100's of feet.A couple ofmy friendsrunning serious stroker motors, ran car tires,YES, car tires.We rode together all the time,they never had a problem keeping up.These guys went through a lot of tires in a season and could buy several car tires for price of one bike tire.I can still smell the smoke!!!.
