tire pressure

Don't even think to don't inflate to 110 PSI for that weight.You will have problem to find a place to put so much PSI.Tire shop can't inflate to that pressure only 90 PSI.If you don't have a compressor to pump that much truck stop have them.

I'd keep them at the 110 psi that is indicated on the sidewall. Under inflating will cause more sidewall flexing which = more heat. Of course you can run them at any psi you'd like, but I kinda trust the engineers that designed the tire and say run 'em at 110 psi. That's what I run my S637 ST235/80R16 LRG Sailuns at on my 15,500 rig.

Thanks Buc and Bob. 110psi it is

I second.. or third ( ? ) 110psi with that weight

^^^^^^^^^^^^^^ What FTG Said ^^^^^^^^^^^^^^^^^

Are you talking double axle or triple axle? A triple axle 5th wheel will have about 16,000 lbs. on three axles or around 3,000 lbs. per wheel. I run about 2500 lbs./wheel on my triple axle and inflate to around 90 psi. A double axle 5th wheel should probably be run at the max sidewall pressure.

Max pressure is required for max carrying capacity. Not max carrying capacity, you can run less pressure if you so desire. Over 5 years and 20,000 miles running my Sailun at 95 psi and they still look wonderful.

Don't blindly air tires to MAX unless the actual load dictates it! Use the weight/inflation chart for your tire then add 5psi.

OMG, you are NOT running MAX pressure?????

Same for me 95 psi, I never dared run the G614's anything but 110, for fear of a blowout. Sailuns ,no problem running according to a weight chart.
