To be exact you have to do the math. No way around it. If you want someone to tell you what pressure to run go to a tire shop and ask them...you will get 5 different answers from 5 different techs... here is a link to good information http://www.tirerack.com/tires/tirete...e.jsp?techid=1

There is also a link on that page explaining load ranges

Happy weekend homework

I don't mind doing math at all, I'd rather do the math than have some tech make a ballpark estimate, which could end up being way off.

I just can't find the data or the formulas for the math...that's the problem.

You need to check the load of your vehicle. You can be precise and weigh it or you can be close and use the sticker. From there you need to find the load capacity of a load range "d" tire. Calculate the headroom (add the capacity of the two front tires and subtract the load - whichever way you determined it). Do the same for the back. Now compare the load capacity of your load range "e" tires (its on the sidewall of the tire) with that of the "d" tires. This will give you the percentage of load your "e" tires can carry over the "d" tires. Now you have all the data. From there it is a matter of determining what percentage the max pressure of the "d" tire is compared to the "e". Next forget all that data and look at the sidewall of the tire it will tell you the max load at max pressure. If your load is less than that go close to max. Don't mean to mess with you but this tire thing started out with you saying you'd like to understand it but basically didn't have the time. Since I'm almost the only person piping up on this apparently Jeep people don't argue over petty things like tire pressures the way POP up camper people do. The tire manufacturer has given you the number you need on the sidewall of the tire...trust them they engineered it.

Re: Can't get my wj outta 4lo?

I should really just call this thread the "Wanna help Fin Thread". Having a lack of car knowledge at 16 is normal I guess, but anyways...

So I had all the tires at 33 psi on Wednesday afternoon. Went on a trip to Central WI to ski for the week, until this afternoon, came back and checked the pressures in all of my tires. 32 in both rear tires, OK, good. Went to the front right tire, 29 PSI, alright, not bad. Seems normal. Went to the front left tire...23.5 PSI...wtf? By my(often flawed)logic, this can mean either 2 things. 1) My tires are seriously f'ed up. or 2)The weight distribution in my Jeep is causing this.

Or a potential third: A combination of the two.

I would first check if no air is escaping from the valve stem.

Checked today again, and that one tire still reads 23.5 psi. This is with a digital gauge, mind you. I think that this could have something to do with it-upon arrival from my trip, that tire was covered in a huge pile of snow, and none of the other tires were.

Steam was coming out of the radiator Friday morning after a ~9 mile drive. Looked at the engine temp after a ~10 mile drive today and it was more than halfway up the gauge...
