F load range = 95 psi
G load range = 110 psi.
Most likely your wheels are 110 psi rated and can use the 110 psi if needed. Best to find out though...you sure don't want to over pressure a wheel. I've seen load F tires on my equipment trailers go to 104-106 psi at interstate speeds and carrying a load.
The Endurance has been out for over 3 years now and so far there has been very few complaints ...like in tread separation.
If it matters they have only 8/32nds of tread depth which means 1/4" of usable tread depth. Its a poly carcass tire and good for maybe 18k-22k miles before time for replacement.
Now if your the type of rv trailer owner who expects 40k-60k miles in a 7-8 year period then the commercial grade all steel ply carcass Sailun S637 ST235/80-16 G at 4080 lbs capacity is at the top in this class tire.
