Cool uhhh I hate to ask but...

WHat tire pressure are you folks running? I have the stocker size and was wanting to maximize longivity and get the best gas milage, I am not worried about comfort its a D-90. O yeah I searched and can remember some discussion about this topic but yeah. thanks folks.

I run with 6psi but that probably won't meet any of your criteria...little squishy in the turns.

I put more air in them when they get down to about 10, then I stop filling them someplace in the 25 to 30 psi range depending on how much of a rush I am in. But thats S not stock, and Jon's and Jimmy's ain't stock none either so you can't go by them. Fill them until they look good or until they pop, then drop the pressure a little, but for trail use, deflate until they fall off the rim, then inflate them a little.

If that doesn't make sense, then just pretend I said 28-32 psi is what the book says.

OK, isn't the correct tire pressure written on the tire wall?
Wait wait wait, I have BF Goodriches 265 17R and I just looked at them.
It states never exceed 40psi but also states max load at cold to be 65 psi.

So which is it? Now I am confused for my road travel

cool. 30-35 is what I used to run in the old tires. they had 47k miles on them and still had a safe amount of tread... I think i will stick with those numbers, just thought i would inquire

I came out of a "full service" gas station and noticed that my ride was a bit bumpy. I checked the tires and they were about 70 psi. Were they serious? Hell if I know. I run a bit more in back than front, usually about 30-35 rear, 28-32 front. True of all my rovers.

No No No, the pressure on the side wall is the max safe pressure for the TIRE. Not for the vehicle.
With a lightly loaded vehicle the max pressure will result in a very small contact patch to the detrement of handling.
To determine your ideal pressure draw a wide chalk line across the tread and drive a few feet, adjust the pressure until the chalk rubs off evenly across the entire tire. This will likely be in the 28-30 Psi range.

okay, now this is WAY too much. Fill up the tire, drive.

No no, the chalk method is insufficient. You must accurately calculate the precise area of the contact patch on all four tires, establish a coefficient based on your driving style and road surface conditions in your area, and perform complex multivariate anaylysis.

Speaking of analysis, if anal refers to your ass, and lysis is latin for "destroy" (as in electrolysis etc) is "analysis" when you destroy something with your ass?

Here comes another stupid question. Why would you run more air the back? My understanding is you've got more weight up front due to the engine thus more air upfront. I know in my Disco I ran 46psi in the rear and 30 in the front b/c I used to tow my D90 every where other wise I ran the same pressure front to back.

Speaking of 6 psi, how is your krawlers doing at that pressure? I used to run my MTR's at 6 also and they sucked, I found out they behave and grip much better at 10 psi. The reason I'm asking is I'm getting BL Krawlers soon along with new wheels so I'm trying to decide if I want a new double side beadlocks or I shouldn't waste my money and get regular wheels.

Handling. I'm real finicky about how my truck handles on road, and I adjust tire pressure to get good tracking and response. I find higher rear pressure helps quite a bit. I've even been known to adjust by as little as a pound or two to see if handling improves. 40/46 seems to be about best for my 110 with 255/85/16 BFG MTs.

Doesn't the manual say more pressure in the rear? Remember, the rear axle is positioned closer to the weight center of the car, so the rear tires support more weight, including fuel tank which hangs beyond the axle!

I had to run my mtrs at 10 also to keep them on the wheels since I didn't have beadlocks. The krawlers perform unbelievably well at 5-6psi...ask the guys who saw them last week in NM. To take true advantage of that tire you need to run them on beadlocks at low low pressures. I don't think you will need double beadlocks unless you are going to the 39 krawler which I have heard has had inner bead rolling issues.

Ahhh,

So thats why you were so pissy about the BL earlier. I see. Tiz's truck was amazing, for the 3.5 minutes I actually saw it. If you trailer everywhere, why not just get the RL?

You are of course quite correct and for this purpose I installed a glass covered service pit in the driveway so that I can accurately measure the contact patch of each tire. There are hose connections for each wheel within the service pit so that adjustments can be made to exactly match all tires regardless of actual pressure. This allows compensation to be made for individual construction differences of the tires.
My next project is to develop an accurate and reliable meter to gauge the precise level of BS in posts to forums
