Sailun Tires ?

I am assuming that yours, like mine, are probably the 235/80 (or 85) -16 G rated tires. If so, the maximum pressure is 110 psi. I am running my new Sailuns at 105 psi. The problem with going way under the maximum pressure is the sidewall deflection when you are backing up sharply. I am also assuming you checked your wheels to make sure they are rated at 110 psi. Good luck.

What amount of weight is on the tires? That will help determine what pressure to run them at. I only have about 2500 lbs. on each tire and run around 90-95 psi. Some folks run lower, but I would feel uncomfortable running under 90 psi. But that's just me.

Air to max pressure 110 PSI. I want maximum capability. I'm not trying to dial in the pressure to the weight. I think that's a problematic approach.

Gotta know weight loading on the tire. Then adjust pressures accordingly.

That sounds good in theory, however does that mean you are weighing each tire individually?

kzspree320 yes they are the same tire as yours. And yes we talked to Grand Design and yes the wheels are rated for 110. We assumed since psi was 110, that we should have them around 95 . We have no idea about tire weight. Thanks to all of you for your info. WE appreciate it! Tara

Per the trailer experts (they build and repair BIG trailers) who installed the tires and going by my most recent weight ticket, I was instructed to run the G-rated Sailuns on my 337 at 105 PSI. That's what we've been doing for 10K miles. The wear is even, the TPMS says they run cool, and the rig handles very well.

Seems like a lot of work to me. I'd talk to the tire manufacturer before I'd take someone elses word.

second chance - Thanks for sharing your results running at 105 psi. Nothing better than hearing what has actually worked long term in the real world (not just inflation tables and charts). I appreciate it.

Can anyone advise where one can purchase Sailum Tires? There does not seem to be any dealers in the US.
