We have utilized 19.5" wheels and tires from Rickson Truck in Hunt Valley, MD, for 11 years and 90,000 miles. With a heavy SRW rig we have been safely and comfortably all over North America with no problems at all. We have a set of 16" Nitto Dune Grapplers for over sand use on Assateague Island. We are on our second set of 19.5" tires, age not wear was the reason. I would not travel as we do with out "H" rated 19.5" tires. Duallys are not permitted on the beach at Assateague Island so that we had to adapt a system that was capable of handling the weight of our Lance 1121 and the F-350 CC Diesel. There is no doubt, in my mind, that these tires are as safe as can be for carrying the loads we have with our large TC's.
