After finishing the 70 resto this spring have been the tractor as often as we can to break in the new engine. At one of the Fair pulls in the 6500 and 7000lb classes one of the seasoned puller noted my rims are too small for the 15.5 FireStones 12" instead of the 14" required. I assumed airing them down till the lugs were making full contact on concrete would be enough which was 9lbs. I finished in the middle of the pack in both classes. Also the tractor weighed in at 6400lbs.
Anyone have anything to say about rim size?
