IMO run carbide tip studs, with chisels its like ice skateing when you lock them up, unless its only going to be for drag. I love my carbide studs, because i cross alot of streets while riding the river and after about 4 weeks my regular kk studs were junk. I run 65 studs per tire and hook up great of the line. If you going to do more track, use regular screw in studs like someone said above.
