Sailun S637 on 3200lb Capacity Wheels
I'm really wanting to do the Sailun S637 tire upgrade on our fiver when we take delivery, but I'm worried about the wheel capacity. I've been told that I would be ok to run 95-100psi in these wheel...

IF wheel is stamped for load rating of 3200#, it CAN equate to what tire one can use. Example.: An E rated Michelin XPS RIB has a weight rating of 3020 pounds at 80 psi...OP's wheel is rated 180# more than that, all is good....If you go to a G rated GY G614, rated at 3750# @ 110 psi, which is over wheels rating by 550#...wheel won't take 110 psi..so wheel rating can be looked at both ways..
in know you can run lower psi in tire's, but one has to also take into wear on tires and when turning unit around and "skewing" tires in tight turn.
Nah, we'll have to just disagree.
That LR-G will carry 3020# @ 80psi just as well as the LR-E will carry 3020# @ 80psi. (better safety margin actually) It won't sag any more, won't heat up any more. Load charts, if you can find them, prove it. There might be 5psi difference due to the stiffer construction. Personally I would go on up to 100psi, but would NEVER exceed the 3200# wheel rating, or the original trailer GVWR.
