White Elephant 01 8.1 burb.

0.5MPH @60 is about as close as they indicate from the factory. Sometimes the gauge isn't exactly the same as the VSS and VSS is more important since that's your odometer. You get a slight change with a different brand tire anyway, or even just new tires of the same kind.
 
Tire review, here Goodyear Wrangler Adventure w/ kevlar, all season, snow rated.
Well it totally sucks in the sand.
bought some desert Trac paddle type tires for dune buggy. Out blasting around the Oceania Dunes, having tons of fun. Got a flat. Drove out of the dunes, found some Manx club members camped on the beach. Tired to air it up, no good. Got ride to get my burb drove out to ohv area little sketchy in a couple spots, but made, thought I picked a firm enough spot to stop.
Changed tires loaded up. Drop air pressure in rear from 50psi to 36psi, try to pull out nope. Digs in. Had to get tugged out by this.

G20 conversation. Early Blazer driveline, part time kit np203 and 10bolts.
Got my burb to wetter firmer stuff dropped air down to 26psi wife drove burb out as I followed in dune buggy. She blasted across the river, maybe 8" deep and 30' wide.
Made it out. Not buying this tire again. Has been fine till today have has it on desert dirt and snow, no ice though, fairly quite,performed OK. Next set will be bigger and more aggressive.

It doesn't matter what you have the burb is heavy.
Sand needs floatation so you need wide or aired down.
I spent my time on the beach with my g20 2wd with highway tires.
Always had to go to 25psi and never had a problem.
235/75/15
4wd would help a little but if the tires are narrow it will dig in
 
Tread doesn't matter as much as tire pressure in soft sand. Air down as low as it'll reliably stay on the bead. There's a big difference between 15psi and 20 believe it or not.
 
I can't imagine hitting the sand at 50psi! Probably a load range E / 80psi tire, so that's probably street pressure. 26 is probably where you should have started. I get it, the tow rig wasn't planned to hit the sand. At Silver Lake they used to say you could be kicked out if they found you with 20psi. I used to just pull the valve cores until the sidewalls bulged, then put them back in and evened the 4 out. 8-10psi in the 38x15.5s floated great and with double beadlocks no worries.

I got a burb stuck on a beach the same way. The 6.2L wouldn't even turn the tires. Some guy walked over and started pushing!
 
I agree with @Blue85 , 36 psi is worthless in the sand.

They say 15 psi with stock size truck tires.

I run 10/8 psi front/rear with 35 - 37" tires. If you run more it just wants to dig down and not go forward. Of course you have to air up before you go back on the asphalt so you don't ruin the tire edges relatively quickly.

When I had my load range E tires, even then it wasn't very god compared to a lighter tire with more flex. But it was still a night and day difference to even 12 psi.

Now, if you are going fast, don't be running 8 psi and think you can make sharp turns, but for what you were doing you need to air way down.

If you can't see the tires bulging, the pressure is too high for low speed sand stuff.

These trucks came with 245/75/16 80psi tires stock, which is pretty much worst-case-scenario in a rig over 6000lbs. I don't know what size @Wes Harden is running, but I'm sure it's far from giant.

Yes that is the size I am running. Had 265 75r16 when I purchased, they old and noisy Michelin s
 
idk I have $200= in some Fragola fittings and braided hose for the 77, and i still have to make those. The El cheapo Evil Energy I fixed 2x and it still leaks
 
Fittings and hose add up! I'm looking at -10an fittings for my oil cooler and the (4) are gonna be over $120.
 
Are you saying you'll have some -10 fittings for sale soon?
 
I was looking at that...let me know if it works...seems a little too easy to be true.

I bought a new truck, an 8.1 LT Suburban 2wd. Going to be the new tow rig, and will allow me to do the bigger updates the 77. She has 137k on the clock. Exterior is fair clean, the "chrome" door accent has peeling clear cover, paint is all good. Windshield has nice long winding crack, and tires are old an cracked. Inspecting at sale, was easy to see that it is mostly original, under the hood. I also saw that the hydro boost had been cleaned, and sure enough it is leaking from the front seal.
immediate plan is tires, need to decide 245 75r16 original size or 265 75r16 current size. New coolant hoses, inspect rear heater and lines, replace hydra boost, Taylor 10.4 mm spark plug wires and new plugs, trans service, oil change. Am considering replacing the crank sensor just be cause.

Wes, does the trans slip? (Going with taller tires on a tow rig...) That 8.1 outta do great
