Goodyear endurance vs sailun s637

[Gainestr]

I’m curious about the Endurance tires you installed. I’m looking to replace my RV tires as well but the lower load rating of the endurance tires compared to the stock westlakes has me stopping from making the switch. Endurance has load index of 123 or 3417lbs per tire which is actually more than 400 lbs less than the RVs gross weight when fully loaded. This doesn’t make sense to switch to. I want a tire that is rated over the rvs gross weight. The Westlakes have a load index of 124 or 3527 lbs per tire. A much more appropriately sized tire for the 337. Westlakes are not a great tire so I’m just curious if you took this into consideration when you put your endurance tires on your rig?

I ran GY Endurance ST235/85R16 LR-E on my Reflection for 3+ years. It is a solid tire, seems to wear well and never had any issues. The speed rating was a plus (although never tried to push it). Ours was a lighter trailer though, so I ruled out the stiff sidewalls of a LR-G tire. If a heavier 5er... then I would be looking at the LR-G.
