Wheel able to handle G rated tire
Purchased a new Jayco 5th wheel yesterday. The tires on it are Rainier 235/80/16 load range E. I intend to replace them immediately. I cannot find the maximum tire pressure on the wheel, but I did ...

Op take my advise when your rig is fully loaded take it to the scales and weigh each axle, better yet each tire if possible. I went from "E" to GY "G" tires and the "G" tires did NOT need to be pressurized to 110#.
Call GY Tech Support to confirm for your self that what I am saying is true.
Per GY when up sizing as in "E" to "G" for example use the weight inflation chart for the new tire. Get the actual weight for your tires and compare to the chart. Add 5psi to the heaviest tire/weight pressure rating on each axle. I did this and ram 85psi (the lowest "G" tire pressure) for many thousands of miles with cool tread, smooth ride and good stopping power.
Most likely 85-90 psi will be all you need.
Remember the sidewall number is MAX pressure. Almost all RV's that run "E" tires do require that much pressure.
Great call on the GY "G" tires!!!
