Tire Pressure

[Eah]

Does anyone follow the owner's manual recommendation for tire pressure for an all street D2? Recommendation is 28psi front, and 38psi rear.

I did with my stocks wheels and tires, i run higher with my 265-75's, 32 and 40.

kevinNy- Thanks. I did a search and just ending up laughing my ass off because other people have asked the same question and the discussion turned in to a debate over under-inflate and over-inflate and correlation to over-steer and under-steer, but the question really never got answered.

Stock pressures on BFG 255/70 All Terrains. Little to no visible wear after ~20k.

bshinn- are those 255/70's on a stock D2? Any rubbing? Are they outlined white letter sidewalls?

i don't like that low of a pressure, but i do keep the variable in place. 30/40 for current stock michelins on DII and 40/50 for 235/85 Dunlop RTs for the DI.

I haven't had the truck really torqued up yet, but no rubbing so far. I have the white letters inboard.

I go with the factory recommendations. I don't go higher because I like the ride. And I stick with the front/rear differential because - funny though it may be - on a vehicle with such a short wheelbase, I want understeer if I'm in a pickle.

Dang, I've been running 50psi on 265/75/16 MT's (Remmington Mud Rovers). Says to go up to 65psi if needed for heavy load. On the trail, I lower to 20-25 psi.

This raises another interesting question in my mind though - tire pressure as it relates to mpg. Now, of course, racks, winch/bumpers, driving style, etc also effect this, but what the heck, we aren't scientists - mostly. It would be interesting to see the correlation between the tire size, pressure run, and mpg, if anyone is willing to post. Might help some of us at the pump.

With my 265/75R16s on the DII, running 40/45 I get about 10mpg (rack/lights/winch/atlanta) and I'd gladly change pressure to get better mpg, if it helped.

i do not air dowm any more because i did that once and air down to 20 and broke the beads on both front tires in the middle of a trail.When you have only one spare you have a problem.Also when you have a set up for offroading with bigger tires lift ect you spend money to clear the diffs and then air down to loose an inch cleareace does not make any sense.My brother did the Rubicon with a D1 never aired down.i run 40-50 offroding with a load with BFG 245-75-16 and in the city I ron 35-45 and seem to have a good ride.
