Why the need for such a high ply rating on that small 8500 GVWR TT ?? just curious
Rating D and above to G and ply 10 to 14 --- any info is appreciated.
The benefit of a E tire (80 psi) comes at those higher pressures.
First and foremost for safety.... are your present 15" wheels rated for 80 psi .
Forget about a 14 ply load G tire at 110 psi for that size trailer. Not a good idea. Trailers unlike a truck can be over tired.
I assume your trailer Jayco Jayflight RLS has 15" D load range tires. Most 15" D tires are a ST225/75R-15 D load range radial at 2540 lbs capacity. Four tires = 10160 lb capacity.
Jayco web shows your 26rls has a 8500 GVWR. The ST225/75-15 tire has more than enough reserve capacity for that small TT.
Tire replacement is pretty simple out here in the real world. The only legal (roadside) issue for the trailer owner is the tires capacity has to meet or exceed the vehicles GAWRs regardless of what capacity the trailer mfg installed.
Industry tire engineer/experts like Tireman9 RV Tire Safety: Reserve Load
and experienced trailer owners (rv and non rv) know a 10-15 percent reserve capacity is a good idea for long term reliability.
I would stick with the a ST D tire and keep them at 65 psi 24/7. Starlite and PJ trailers are high on Provider ST radials for their heavy trailers. They should work great on a RV trailer.
If you do a lot of interstate miles per year as many of us do and the ST tires don't stand up then the best upgrade is a LT225/75-16 E at 2680 lbs per tire for that size trailer. And of course check for proper top and side clearance issues for your particular trailer.
One size don't fit all.
