I WOULD LIKE TO GET SKAT TRAK HAULERS 21X12X8 . BUT THEN I WILL HAVE TO BUY NEW HUBS. ALL I'VE FOUND ARE EITHER RATHS FOR $160.00 A PAIR OR HPD FOR 129.00 A PAIR. THEN I WOULD HAVE TO BUY DIFFERENT REGULAR REAR TIRES AND RIMS. I WOULD PROBABLY GO WITH THE 4-115 YAMAHA BOLT PATTERN. ANY OTHER SUGGESTINGS. ANY ONE RUN 21X12X8 SAND TIRES????
