    wait, so you run 45 psi??? You are crazy! Running that much pressure is going to be great for gas mileage, but your traction has got to be hurting from that. I run 29 psi.

    getting there....
    it really all depends on what kind of tires they are and if you care about mileage/wear.

    i run around 31/32 in my front tires and 29/30 in my rears.......wearing pretty good too. if you have inflation set too low......they will wear weird and mileage will decrease........set too high, mileage will be decent, but they will wear weird there too. whats in the book is based on the truck being loaded(trailer or bed), run what you are comfortable with.......but dont go above recommended pressures for the tire or manufacturer recommendations. just my .02:)!

    Wait..... In a good take-off (and I mean, really good take-off), isn't that the whole point (and fun) to burn off a little rubber? :p

    Lower tire pressure gives you a bit more traction and grip on the asfault.

    I run about 32psi in my tires. Anything harder than that can lead to premature kidney failure. It's just too damn hard on the body & the vehicle.

    You're running 45psi? Holy crap....doesn't the truck get a little *hoppy*?

    I've been running 35 psi in mine. Seems to be a middle ground between comfort and mileage. I've got the stock Rugged Trails, so I'm not too worried about them wearing early.

    If you're talking about putting MORE PSI in then you're going to have less traction, not more. I'd stick right around 30-34 PSI. I'm at 34 but I have aftermarket tires, though.

    My door sticker calls for 29 front and 31 rear. I've been running 1 or 2 PSI over that and the ride is pretty good. Last summer my bumper was tapped and when I got the truck back from the body shop the ride was teeth rattling harsh. One of the little perks the shop does is detail your car and as part of it they did me the favor of setting the tire pressure to 40 PSI all around. :eek:

    Run your pressure too high and you'll burn down the center tread. Also, you'll lose some of the contact patch, your only connection to the road.

    Case in point after 4 winters, my snow tires are 8.5/32nd in the center and 11/32 on the outside cause I ran them 4-5 psi too high for the first 3 winters. The rubber compound is much softer (they only last 18-20K), but you get the idea.

    I tried to come up with an answer for you but couldn't. Try as I may, it just wasn't coming to me. I then noticed the problem.

    No captial letters, no periods, commas, no question marks, etc.

    I wasn't sure if you were telling me something, asking me a question or your cat walked across your keyboard. :confused:

    Come on brother. :wink:

    Now, back to the question. Run what is recommended in the door jam. Those engineers are a hell of a lot smarter than you and I. [​IMG]

    Agree.

    Yes, I agree ... it does sound crazy. Higher pressure equals less surface contact which equals less control.

    Agree.

    Recommended psi is best ... hands down.

    On a similar note. Dealerships by design keep low tire pressure on the cars/trucks in the lot. When taken for a "test ride" the lower tire pressure assures them that you'll get "a nice ride."

    Whenever I've gone in for a vehicle. I have taken a tire pressure gauge, checked the psi and had them bring the tires up to recommendation before leaving the lot. I know they have thought that I have been a pain in the ass but on more than one occassion the salesman was impressed.

    Okay .. time to step down off the soapbox.

    When I had my tires set at 35psi, it gave me a harsh bone jarring ride.

    Now with the Donahoe setup and still with 35psi, it rides like a Cadillac.

    29 PSI Cold? How cold California cold or Minn. cold? How could they ever be the same. At zero the tires do not heat up as much as when it is 90-100 here. I keep mine at 32-33 and check them at the coldest , non-moving tires early in the morning, no sun on them either. If I needed more traction it would be lower. I check them after they are hot see the difference....Rich

    When they say "cold" they don't mean the weather. It just means to adjust the tire pressure at least 20 mins after driving. It explains in your manual

    Further to that...In yesterdays paper there were tips to improve fuel mileage and naturally one was to maintain proper tire pressure.The article stipulated that "cold" is when you haven't driven at all or less than 2 kms.
