S637 Sailuns under 110# pressure?

A boondocking friend has Sailun tires on stock 80# wheels on an 06 3400rl. He has run them at the max wheel rating and is having significant wear on the shoulders of the tread face, inside and outside edges, front and back axles. His rig is around 13,500 axle weight. He will be upgrading rims. Classic overloaded under inflated scenario.'

Yes our first Montana was a 06 3400.The axle weight was increased on the 2007 Model year. They were 80psi rims on the 2006 ...period.

CaptnJohn, when they looked at the rims on the 2014 HC they could not find any psi stamp. When I contacted Keystone they said they were 110 Psi but with the lug nuts of only 5 I wonder. Also tire shop said already had separation on one of the tires with a bulge. I checked them and never noticed that. Either way I feel good and safe for now!

Sometimes the wheel psi is on the inside, only seen with the tire off.
Although I do not suggest it, my Cougar had 80# wheels. I ran them at 95 cold always without a problem.
There are only a few wheel suppliers out there. I sent the question with a photo of one on my Cougar to a supplier that told me it was not theirs but who actually did supply it. Agree, 5 lugs generally indicates 80# ~~ Keystone should know, but I'd try to find the supplier or keep it under 110 by using the tire manufacturers weight chart.
