Run Sailuns at 80 psi

[twindman]

I only have 80 psi rims and only need about 3000 lb per tire, so I think the sailuns are rated around 3400 at 80 psi. So my question is will these ride really rough. Also is there any other problems?

Maybe you should ask yourself why you purchased tires without purchasing the proper rims for maximum performance of the tires.

The trailer in my signature is about 2000# lighter then yours and I carry 90psi in my Sailuns and it doesn't seem to ride rough. I'm sure my rims are rated for only 80psi too but will be changed after I get home in December.

If there are any questions as per how much your rims are rated for psi all you have to do is crawl under your unit or pull a tire and rim off and check the back of your rim. The rating is stamped on the rim and will tell you which tire pressure your rim is rated for. In some of the seminars that are put at the National Fall Rally by Tredit (the supplier of tires and rims for Keystone) it has been recommended to use the proper tire inflation per your rim. Under inflation can cause just as much damage to a tire as over inflation and I think the Sailun tires (if you are putting on the G rated ones) are rated at a110-120 psi rating. Yes, you can run them at 80 psi but they will heat up faster and wear faster because of this. We have a 2013 unit and our rims are aluminum and they are rated at the 110-120 rating. The Mountaineer may have a steel rim and rated at the 80 psi, I don't know for sure but contact the manufacturer of the tires or look up the pressure ratings suggested by the manufacturer to be on the safe side. Good luck and happy glamping!

I know my rims are 80 psi, as I moved them from my 2006 Montana. I had just put new tires on it and wanted to keep them, so I had dealer swap out the tires/rims. I didn't realize that the 2013 model had 120 psi rims (I think). Just thinking of the future as I have probably 2 more years or maybe 3 left on my tires.

I doubt you'll notice the difference of 400lbs at 80psi.

I have a 2012 Mountaineer, and my rims are rated 110. Check the back of the rims as suggested. At about 95 pounds, my sailuns shake the crap out of the camper, but it’s better than a blowout.

I would suggest you find out the reason your "Sailuns shake the crap out of the camper" before they do more damage or blow out. They either need balancing or replaced. There is no good reason tires should shake that much.

I suggest you haven’t done a lot of driving in Oklahoma or Missouri.

If you think they're bad you better stay out o Iowa. Couple years ago I was in MO. & OK thought the roads were decent.

Have driven many a mile in Missouri, east and west on I70 & US36, north & south on I55 & I49 and many a mile on state roads that I actually thought were pretty good roads. Granted, I haven't driven as many miles in Oklahoma although what I remember seems to be they were pretty good roads but I've driven across Indiana and believe me when I say there are no worse roads then I70 east bound. In any case I have not found my Sailuns to shake very badly although Indiana did cause me to slow down due to such bad roads.
