Looking for 215-75 17.5 H
I bought 235/75R17.5 Roadmasters for $180.00 each. It is a commercial all position tire that has a load capacity of 6,005 pounds per tire.
Be careful they are only 62MPH rated. I would bet they are a rough riding SOB when loaded to 125psi.
Actually they ride no different than the 16's I replaced. I ran them at 80 psi, per their chart, which gave me a capacity of 4500 pounds, all I needed was 3,500. First time out with them, my fuel mileage was down 1.5 mpg, and they ran hot!. I aired them up to the 125 psi for our next trip, temps where in the 90's, tires ran cooler than the truck by 30*, fuel mileage came back up.
I run the speed limit, and yes that is 70 mph. I am running at half the capacity of the tires and it is running cooler than the 16's I had by 30*+. Heat is what kills tires and causes blow outs.
