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 wheels with metal stems. Fiver is a '16 Jayco 326 BHQS with a gvwr of 14k.

Thoughts?

I confirmed with local tire dealer today. He says that it is no problem running 110psi in that wheel with those tires. He states that overloading the wheel weight rating is what will cause wheel failure. I've dealt with him for years and he knows his stuff. I'm not saying he's right or wrong, but i do value his opinion and feel it trustworthy.

I also know between this forum and the Jayco forum that several are running the same setup on the same wheels.


Then the wheels must be rated for 110 psi..The 2016 Jayco Seismic 4112 had 3 axles and a GVW of 21K..Those wheels will take 110 psi.

The wheels are a direct match in the stock wheel appearance and the tires are 235-85R16 "G" Sailun tires.


Would you care to share a link as to where you purchased?

I run my Sailun tires at 95-100 psi., but that's 15-20 psi over your wheel rating. Personally I wouldn't run mine at less than 95 psi. And I don't know that I'd feel comfortable running my wheels at 25 percent more pressure than rated capacity. Who told you you could run 95-100 psi. with those wheels? If it was the dealer, make sure you get that in writing.

The sidewalls are really stiff and running at 85 psi. might not be an issue, but I'm not a tire engineer and can't really say.

Then, I would think, wheels are only rated to 80 psi.. but could be wrong
