I'm looking to trade my loaded turf tires for a set of R4 tires. Preferably loaded also but not a deal breaker. The turfs are in very good condition and good tread. They are for a 3520 and size 41x14x20 for the rear. The front is 27x8.5x15. Will meet half way if distance is reasonable. I'm in Muncie Indiana 47304. Pics upon request.
