If you do decide to go the Samson route, make sure your wheels are rated for 110 PSI. Also the best price I got for my Ribs were at a Discount Tire in Henderson, NV. And availability was no factor, of course this was due to the area. This summer I have been pricing Mich MS tires for the truck in Montana so I could skip sales tax in other states. Well my wife went on Discount Tire's web site, picked the Henderson store and their price blew the prices I got in Montana including NV. state sales tax out of the water. So on our way down to Yuma, AZ. for the winter I'll be back at the same shop. And prices are locked in for 30 days.
