Recommended 16 Inch Load Rang G Tires For A 2020 Jayco Pinnacle 5th Wheel

Question:

I currently have Goodyear Endurance 255/85r16 load Range E tires. Can I go to the Westlake ST235/85R16 load Range G with the new rims rated at 110 psi. I know the tire is a little smaller. This is on a 2020 jayco pinnacle 5th wheel.

Going with the slightly smaller, yet higher capacity Westlake ST235/80R16 Radial Trailer Tire # WE76FR will be absolutely no problem at all. The Westlake # WE76FR will have an outer diameter of 31.7 inches and a section width of 9.3 inches, whereas a Goodyear Endurance ST255/85R16 has an outer diameter of 33.07 inches and a section width of 10.04 inches. So between the 2, there really isn't too much difference in size.

The # WE76FR will up the capacity of the tire to 4,400 pounds at 110 psi and is 14 ply, but will lower your speed rating to an L, or 75 miles per hour. This is where the big differences will be. With that said, if you are ok with using a tire that is slightly smaller and has a lower speed rating, but also has a higher weight capacity, I can highly recommend the # WE76FR.
