Our 5ver is running 2700 lbs on the pin and 10800 lbs on the axles. With the Goodyears, I could pull off the interstate to check the tires, and you could feel the heat radiating off the Wrangler HT's from 3-4 feet away! We went on a round trip from Houston to Nashville, TN this summer. I ran 70-75 MPH through Tennessee on I-40, and when I pulled into a rest stop, I could literally put the palm of my hand on the treads of the XPS Ribs and leave it there as long as I want. What a difference!
I guess the load range F & G Goodyear G159's are worth a try if you need the load rating. Often, however, to take advantage of the 110 PSIG tires, wheels may have to be changed as well (they have a maximum load and air pressure rating as well).
