Weighing Class A for Tire Pressure

I have a 2003 monaco knight 34ftdp. Weighted it front and back and total, no 4 corners here in Yoakum, Texas lol. front 7900lbs, rear 16,140lbs, total 20,040lbs. Tires are toyo 255/70/22.5 what pressure do i run? Sticker behind drivers seat is unreadable. I found a formula some where on web but cannot find it again. I think it was ft weight div/2 x 1.05 and rear weight div/4 x 1.05 Any help would be appreciated.

Somewhere, probably very well hidden, on the web sight for your tire manufacturer you will find the inflation chart for your tires. There will be two values. One for a single tire and one for the tires in a dual configuration. That's where you use your weights to figure out tire inflation. Good luck.

Try this web page https://toyotires-1524598101.netdna-...on-table_0.pdf
Looks like if 80 front, 85 rear but please check everything yourself and adjust as necessary for your application.

Escapees RV club is a good one to have your rig weight and tire pressure figured out. You are a 200 mile trip from Livingston Texas which has the Smart Weight program. SKP is a pretty good RV club to belong to so maybe look that up.

Just a thought.

At 80 psi your front tires can carry 4190 lbs each and the rears at 85 psi can carry 4110 lbs each...a decent margin over your weights. Assuming your rig is not out of balance side to side I would use 80 front and 85 rear.

It doesn't change your axle weights, but your total weight is 24,040 lbs by your "each" axle weight.

To determine what the right tire pressure is for you, you need to weigh your MH. Load your MH as you would for travel, fill you gas and water tanks and then get your MH weighed.

If you can't do 4 corner weighing, this is the procedure to follow:

1. Weigh the coach axles
2. Add 5% to account for possible uneven weight side to side.
3. Divide by the number of tires on each axle.
4. Look to tire chart for your brand to find tire pressure.
5. Add 5 psi for safety

Note that the front 7900# plus the rear 16140# adds up to 24040. That should have been the reading you get with all wheels on the scale. (or at least close to that).

If you can straddle the scale so you can weigh front & rear on the right and left sides separately you can figure individual tire weights. This may give a more precise weight result than a guess that sides differ by 5%.
