Tire PSI for hauling firewood

[South VA]

Suburbans are different than p/u's

Correct. However, a 3/4 ton truck and a 3/4 ton Suburban both specifiy different pressures front/rear.

Gotcha. Never had 2500# in the back of a burban so I'll defer.

Not sure I have either, but towing plus stuff in the back will certainly get it there.

Towing/tongue weight is a different animal, imo

50 front, 80 rear is what an 8-lug Express van calls for loaded or towing. Find it works well for me. 50 psi front/rear unloaded.

You're only going to be hauling this load for a short time and I'm guessing in cool temperatures. 2500lbs is a pretty good load so air the rears up to max and add ten to the fronts. Airing up the rears will help to reduce rolling resistance and you will be adding a little more load to the fronts. Once you get the truck unloaded let the air out to what you were running before.

Pickup trucks are almost always light in the rear so normal rule of thumb is to run the rears with less air than the fronts. Only way to know how much air to run is by tire wear. If they wear the middle more than the outer edges then you have too much air in the tire,if outer edges wear first then not enough. A tread depth gauge is a handy tool to have for determining what air pressure you need to run. Measure outside and center of your tread depth when the tires are new,write it down then measure in 500 mile increments and adjust air accordingly.

Your vans are heavier in the rear than PU's. 42-46 would be closer for rear pressure for a truck in the unloaded state with those tires. My tires are rated for 50lbs max pressure at 2250 max load. I run 44 in the fronts and 36 in the rears and so far the wear looks pretty even and I have good grip in the rear.

Suburbans are different than p/u's

Well, just for fun, I searched a bit and found this:

1992 Chevrolet K2500 Tire Pressure

1992 Chevrolet K2500 tire inflation pressures with the recommended tire pressure, trims, original equipment tire size sets, winter tire pressure, tire load index, tire speed rating and other information.

tirepressure.org

It would seem that the P/U and Suburban are, as Keeper said, different! I blithely assumed that the f/r tire pressures would be comparable for both vehicle types because they were both K2500 vehicles; but no, they’re not.

According to the chart on that site, the P/U runs the same PSI front and rear. Quite different from the Suburban.

I was wrong on this, and need to correct it so as not to spread misinformation.

Sorry about that, @Komet and @Keeper. Sometimes I’m a bonehead. This is one of those times.

Actually they do. It’s on the Certification sticker. Load range E.

Sorry but, no they don't, load range E is also a suggestion (CYA), someone is going to use something different and need to adjust accordingly
