Tire Pressures

[jlouns]

I am a new RV'er with a 91 Class A Winn Warrior 30ft
I am wondering if anyone has some ballpark tire pressures (cold or hot)
for the front and rear tires.
More I look, the more different answers I get!

Thanks

go to the michelin tire web site

and then click on RV Load and Inflation Tables and you should get the answers you are looking for,

Do you have a sticker some where near the drivers wall that shows the data for the motor home ? That will give you a rough guess.

Weigh the front and the rear. Then go to the tire mfg web site as listed above.
They will tell you how much pressure depending on the weight on the tires.
When we bought our last RV they had the tires up to the pressure on the sidewall. That was 110 lbs. It drove as though my fillings would fall out.
We weighed it on the trip back. We bought in Oregon and brought it back to Calif. After weighing we ended up with 85 for the rear wheels and 75 for the front per the web site for the tire mfg.
All the difference in the world in ride. Very nice now and my fillings are safe again.

Good advise from thewiz and browzin.

Weight the rig, both ends, as close to trip ready weight conditions as you can. Refer to the load charts. These inflation figures are the MIN pressure to support the weight. Since the listed pressure is less than the pressure molded on the side of the tire on my rig, I add a couple psi just in case we gain a few pounds while out on the road.

Oh, when you weigh the rig, it's best to weigh all 4 corners. Any inbalance side to side, inflate to the needed pressure of the heavier side. All tires on a given axle need to be inflated the same.
