ummmm we are on the 18th set of rear tires. Some times we get to the point where the tires will not last another comp, so we just have fun and burn them off. 1 set of tires will last us 1 event, but it also depends on track setup and tires. Some tires are better on fast track while some are better on tight closed tracks. oh yea and Evil8s 2 tires..:thepan:JOEYCTS-V said:I'm just curious how many sets of rear tires have you gone through so far?
