An RV owner should weigh their fully loaded RV to
measure each tire’s load per axle. We can do that at the GMCWS meetings.
As a backup, we can measure this at a Pilot Flying J refueling station
for $10, but Flying J normally measures all the tires on an axle.
When you know your maximum weight per tire, you can look up your
tire’s size on this chart and find what pressure you need for your highest-
loaded tire on that axle. You may also find out if you need to buy
larger or higher pressure-rated tires to carry your fully loaded over
specification coach.
Tire 1=LT225/75 R16 LRD (65 psi max) or LRE (80 psi max) fits
the Alcoa Classic 16” wheel, Tire 2 =245/75R16 LRD (65 psi max) or
LRE (80 psi max), Tire 3 =8.75R16.5 is the original bias light truck
wheel and tire combination that was used for the first three years of
production. Fabricated steel wheels also have larger out-of-round tolerances.
You can find the tire’s information and its maximum pressure
molded into its sidewall.
Tire 35 psi 40 psi 45 psi 50 psi 55 psi 60 psi 65 psi 70 psi 75 psi 80 psi
1 1500 1650 1790 1940 2060 2190 2335 2440 2560 2680
2 1700 1865 2030 2205 2335 2480 2623 2675 2900 3042
3 1800 1840 2005 2165 2350 2515 2680

Several other weighing options
1. Stop by your state highway weight station. Most leave the scales on when they are closed. 2. Stop by a local grain elevator. Most will let you drive over for free.
3. Stop by a truck stop that advertises CAT scales. Cost will be around $10.00.
4. Come to a GMCMI rally or the Bean Station work rally. We will weigh it for you.
5. Stop by my hangar in Valparaiso, IN and I'll weigh it for you.
