What tirepressure do you run? Street vs Trail

[Geargrinder]

Yes, that's a way to do it but a laser temp gun sounds very expensive. I was thinking there was some kind of formula you could use to calculate the amount of air in the tire (pressure and volume) that is neccesary to carry a specific weight. Humh....That sounded very complicated.... .

That's what I thought till I got one. I got mine for about $45, and I use it alot. Good for finding clogs in the cooling sys. good for checking CV joints (if U have a rig with 'em) Good for checking batt. cables (hot spots are bad) And the tire thing too! My tires are wearing PERFECTLY FLAT I figure it's worth it for that alone, my tires ran me about $500 so if this will get me an extra 5-10,000MI on 'em then it paid for it's self. It's good for keeping tabs on the winch too.

Re IR/Lazer thermo. After reading this thread, I ordered one this AM.

That's a lot of air. I would use 32psi for 29" tires. Notice that Geargrinder found 28psi to be correct with 35's on a Burb. A K-5 is lighter and would need even less, although it's about the same thing I use.

I could probly go lower, but I went by BFG's recommended for max load. I do alot of hauling. Old engines trannies axles, chopped up trees, junk to the dump, gravel, rock. Even with the long bed I'll sometimes pile it up to roof of cab. This is why I wont go taller lift or put on bigger tires. Its already a pain loading and unloading the bed with it this high. This is usually the only time I drive it, other than the few miles to Hollister Hills SVRA.

42's on 15x8's: Right around 30 psi (this is max pressure for this tire is rated for) on the street.

8psi rear, 10 psi front on the trail.

I've driven this vehicle to and from every trail ride. In the near future, I'll be towing it. It should be noted that I run the max pressure for less rolling resistance, not optimum tire wear.

4PSI Trail 4PSI street.

Pu$$ys air up on the street
