We have raced forever without issue with a tractor tire, the last 2 out of 3 outings we've had tractor tire issues. The first was a guy hit the tire in front of Pete, pushed it out and Pete smoked it, fortunately it was coming out of turn 4 for the checkers, it required a drag link replacement and 1 spot in the heat race
Last weekend the start of the feature with cars bunched up he gets drilled from the back and straight into the tire, he kept going but had about 1" toe out, which resulted in an ill handling car and a prematurely wore out front tire.
!st tire was too small and moved onto racing surface, 2nd tire was too large and didn't move.
In my biased opinion tractor tires belong on tractors
