I have a travel trailer with 15 inch rims. Are you guys upgrading the rims to 17 to get the Sailun tires?
To replace 15" tires and wheels You sure don't need a Sailun S637 16" or 17.5" tire/wheel at 4080-6000 lb per tire/110 psi. Not the best idea for a trailer with 3750-5200 lb axles and OEM 15" tires.
To determine best size/load range tire for a trailer add a 10-15 reserve capacity above the trailers OEM axle ratings.
Check out some of the new gen L and M speed rated ST tires such as the Provider....Goodyear's new Endurance.....and Carlisle HD. These aren't the old style ST tires that were so problematic to many folks in the trailering world.
Another option is moving up to a 16" commercial grade LT E 80 psi at 2680 lbs capacity mif they fit the trailer wheel wells.
