Subject: Proper Tire Pressure
IP: Logged

Message:
the door sticker on my 02 QC 4x4 says the proper tire pressure is 35 front and 41 rear.. for the 15x7 tires. I have the 16x8 with 265/75/16 tires which are the optional tire from the factory.

I understand that the proper tire pressure should be what the manufacturer recommends, not what the tire recommends.

I inflated mine to 41 psi rear instead of 35 (which is what the company that sold/installed my tires inflated too and recommended) and noticed a big difference. My rear tires don't squeal as much and the LSD doesn't kick in as often either (such as in rain or accelerating out of turns).

What pressure do you guys with 16x8 tires run?

I have Pro-Comp 265/75-16 (about 32").

45PSI front
30PSI rear, unless I plan to carry some loads, then 45 rear also.

I use igher pressure in front because that's where most of the weight is on a pickup, and because the Dakota handles much better if the fronts aren't all mushy from the factory-recommended (under)inflation pressures.

Something you should know: the factory pressures are for the OEM tires, and are usually a bit on the low side to smooth out the ride, and make it ride more like a car..

yes, the sticker on the door is for the OEM tires.. which is what I have.. I don't have the base 15x7 rims, i have the optional 16x8 rims. The sticker only lists 15x7.

I read you can use more air pressure while on pavement than you should use off pavement. the tires at 41 psi in the rear look ok.. no bulging at the bottom where it contacts the road nor all along the side wall. It doesn't look over or under inflated. at 35 psi rear it did look under inflated.

Dan M, one way to see if your tire pressure is close is water down the tires then drive on dry pavement and check the pattern on the pavement, that way you will be able to make sure the tire is making contact from outside rib to outside rib. If it looks a little lighter on the outside edges then you have too much air. You can also do the same thing by spinning the wheels just try to get an even, full, pattern. Then you will have the correct air pressure. The water works, but isn't as much fun as spinning the tires.
Good Luck

Hey Dan,I have 16x8 rims with 255/70/R16 I have been running all 4 at 35 psi stock tire was 255/65/R16 wanted them but at the time very few tire dealers carried them now plenty of choices I got about 25,000 left on these KELLY SARFARI SUV rated at 55,000 miles I have about 29,000 miles on them now and they look worn down and when you do the top of the penny head they need replacement but holding off till get some more cash for a pair Ive been looking at my tire dealer says I have about 26,000 cant be true and I asked a good tire pressure and suggested 35-40 psi depending on what your hauling more weight morer psi less weight less of course notice no difference little better mileage more psi but maybe a bit ridgid

The simple answer is that you need enough pressure to maintain a flat contact patch. That will vary depending on weight, temperature, tire design, etc.

Setting the right pressure according to conditions will make the tires last a lot longer. Well worth the effort to do it correctly.

The best way is to use a tire pyrometer. Get the tires nice and warm, then check for an even temp across the tread width.

Most people don't have a tire pyrometer in their tool box. After the tires are nice and warm, coat the tire tread with blackboard chalk. Drive straight foreward on flat ground about 10'. Look at the chalk. It should be evenly worn off all across the tread.

If more is worn away in the middle, drop 2 psi and repeat. If more is worn on the outside, add 2psi and repeat.

i was skimming though my new ORA magazine (off road adventures - free from 4 wheel parts) and it has an article on tire pressure.

It has some examples of tire size, weight supported and what tire pressure should be.

Hey Dan, what were they reccomendations? are they specific to a make,model,etc.. Ive heard before what .boB done and true not everyone has a tire pyrometer in there tool box I remember this back in Autoshop class sounding stupid and to complex but now wiser and older understand more ? some things? LOL.. I check my tires with a pencil type and a digital shown 42 psi on all 4 filled with nitrogen which means nothing when already 78% of air is so no hype there and been getting mileage around 17-18 city haven't went on highway run yet this year and tires rated at 35 psi. bit baffled, was consdering droping to 35 psi on all 4 since I read your post got me thinking about to my door sticker says 35 front 35 rear but with P215/75/R15 tires and originally came with P255/65/R16 and always set them at 32 psi. And tire pamplet that was with manual suggest 30 front 35 rear under light load and 35 on all 4 for full load reading this under Dakota 2 wheel drive section. So yea I can see alot variables here to me going to tinker with this one and hey least its free mod LOL.. but be careful not to have blowout with to much or to little air to destroy a rim ? and out buying a new tire(s)

They talked about several ways to check for proper tire pressure, one was to use chalk as dot bob suggested.

the also had a formula on how to calculate correct psi. I'll have to look it up in the magazine and post later. It had to do with the weight tire was to support and tire size. They also had sample charts .. what certain tires would be.

ORA is available online (sorta - they are months behind).

you just read the side of the tires!

every tire is marked for max psi.

i would not inflate to that but stay a pound or few under and you will notice a difference in MPGs

grampa's way of running 32 lbs in every tire is long gone
