yeah theres 2 types or 10.5 racing..u got the true 10.5 and then outlaw 10.5..

the true guys run on a 29.5x10.5x15 slick

the outlaw guys run on whats called a 10.5w tire witch the foot print on the tire is really like 11.25 inches wide..they make 29.5,31.5 and 33.5w tires.

most of the time if i put 10.5 on one of my threads it means the outlaw ones..if i'm talking about true 10.5 i list it ass tt5
