I spoke to an expert tire guy from Discount Tire, told him that my 334 which weighs 10,000 lbs had Tow Max load range D tires on it. First thing he said was gettem off there buddy. He gets calls all day long about TT owners having blow outs on brand new TTs because these manufactures install only the cheapest tires they can roll it off the property with. I asked him about tire quality, said Maxxis is the best so we went with 4 new in load range E. I've been fortunate not to lose a Tow Max tire that was at max load, especially rolling past 65 at times.
