The pressure printed on the tire is NOT the maximum. It is the MINIMUM pressure for the MAXIMUM weight that the tire can carry. You have to weigh the rig before you will actually know your correct pressure. Also, you should add 10 psi above the weighed chart pressure. Your 80 psi is probably ok. Your rear duels should show no sign of kissing after a trip. The Beginners forum has a sticky about tires. Order the tapes and they will send you some booklets also. Good luck.....Lynn

I have seen some tire manufacturers state that the max on the sidewalls is in fact the max, and other documentation says you can go 10 above max.

I always thought I had 60 plus pounds in my tires but when I had some service work done a month ago, the tire veteran said the max pressure printed on the tire was 45 pounds and that is all he said I should put in them...drove home from NC and did not notice any problems but I am still wondering what is right...the mechanic was not some young kid...so, who is right??????????

I've read on the forum that duels in back should be 80 each and front 65. Am I correct. Where do you find the PSI number on the tire. Thanks The right way is to weight your MH and inflate your tire according to your tire manufacturer inflation table. NEVER run under that pressure. If not serious injury can happen!
You may also want to look to some previous post Michelin XRV Tires and Max tire pressure versus weight of coach
BTW What is your tire size, brand and brand type?

okay, don't smack me for being a newbie, but I haven't checked mine yet. I have about 1000 miles on the rig (brand new). I looked last night, and I don't have a pressure gauge that will go above 60 psi, so I'll have to get something. Also, something that's odd is that on the outer wheel of the rear duallys, the valve stem is angled IN. I'm not sure how to check this as it's going to be a PAIN to get at. (alcoa wheels if that matters)
Suggestions?
Also, when weighing, should I have my trailer attached, or just calculate for the rear tongue weight?
Thanks. Especially to those who have answered this probably 10x before.

You just need a double headed tire pressure gauge - they are easy to find. Any autoparts store will have one.
I grabbed the wrong gauge once (60 lb max) and checked a motorhome tire. It shot the end out like a dart!

So I just read the thread on the XRV tires.
The thing that tweaks me here is that you'd think this could/would be brought up during the customer walk-through, ESPECIALLY knowing that this was my first RV.
I'm meticulous on my tire pressures of the race bikes because it affects heat/wear/traction, but tend to neglect my vehicles as I've never had a failure. Guess those days are over... Will be checking tonight before we race this weekend...

Motorhome tires have much less margin than normal passenger vehciles. In addition, the wide load variation dictates that the tire inflation be set based on weight. Over and under inflation are both dangerous.

It's funny. After getting the compressor installed in the MH it got real easy to check our cars' tires too. Now I have started playing with them to get the perfect ride. Before getting the MH I would only check a car tire if it looked low.
When I picked mine up and was getting ready to drive 700 miles home I asked the mechanic that was getting it ready to please set the tires. I saw him kneel near the front and was called to do some more paperwork. So, You would assume he did all the tires right? I came home only to fine 60 in the rear after I asked him for 80. When it is a hassle to check your pressures even the mechanic doesn't want to do it. New coach owners should check their tires right away instead of assuming the dealer is on the ball. Yeah right, funny...
