Cool 4 Corner weights

When you weigh your MH one corner at a time to calculate tire pressure do you air up each tire with a different pressure or the same air side to side, or front to back. I probably should know this but I am new to this and still learning. Thanks, Cork

Use same pressure (highest) side to side on same axel. Different axles may have different pressures according to chart. Usually the charts will give instructions about this.

Determine the proper inflation pressure for the heaviest tire (or pair) on each axel, then apply that same pressure to all tires on that axel.

The best way to get a true reading on coach weights is to have a 4 corner weigh. This is where they place your coach on 4 scales at one time to get a true reading, cost $60.00 Mine was done by (Weigh to Go) at an FMCA Rally.
My tires are 295/80R22.5 and comes in at 94%(under)730lbs in the front and 106%(over)1150lbs rear Total wt 12470lbs Front--21150lbs Rear and was told to run 105PSI Front and 100PSI Rear.
RF-6405lbs=LF-6065lbs RR-10195lbs=LR-10955lbs

There are two schools of though, Some folks say to air both sides the same, I say air all tires per their load..

Reasoning: Epically on the drive axle.. The pressure in the tire will affect the tire size (Circumference, the largest night at the round table, Sir Cumference)

And you want the tires on the two sides to be the same size, so air them up per the chart.

Alas, in my case, don't matter, all tires air to max for this rig.

Follow the tire manufacturer's recommendation. Ours are aired the same (highest).

Michelin have full instructions for tyres on RVs and they say air tyres on the same axle to the pressure dictated by the load on the heaviest side.

I would be concerned if tyres were of a load rating that needed the maximum allowable pressure to support the load. Doesn't leave much margin for extra load.

Its hard to find a public scale to do a four corner weighing because often there is no room and/or so many are raised. That will tilt the coach towards the low side (off scales) and skew the weighing. Google scales near you. Check with DOT or State Police in your area to see if they can perform one, or look on this site for a rally near you: RV Safety & Education Foundation
Every manufacturer I have read about wants the same psi in all tires on the same axle. Without a four corner weighing, we are assuming the coach is balanced side to side. If it isn't, and many are not according to the folks at Josams in Orlando, it can lead to under inflation on the heavy side.

We're lucky - if you're in the San Jose, Ca area you can go to Leale's RV for service and they'll give you a 4-corner weigh for FREE!
