how do you folks personally set your tire pressures?

I know this question is very subjective but i am curious to hear what you folks set your tires at? I know some do the chalk test, some do more PSI up front and less in the rear vice verse and some do same PSI all 4 corners. Once again this question is very subjective so no need to attack each other for their methods. Thanks and looking forward to hearing back!

 

Usually I go a few psi more than what the door jamb says. If im hauling some decent weight I’ll go 10 psi more in the rears.

 

I try to keep it at 34psi in all four. Other than my shell, I'm not carrying any additional weight.

 

I have stock size tires so I go by the door reading when the tires are cold and it has been sitting for a while. I know I'll be above that when driving

 

33-35 most of the time in summer

30-31 in winter

28-30 when I'm going skiing or know I'll run into snow on the highway

25-27 if I'm going to be on washboard roads for the day

If the snow gets deep offroad I'll go down to 18-20

255/80/17 e-load

 

I follow this pretty much to the letter.

 

Question, do you carry a compressor with you? That seems like a lot of work.

 

I run 32psi all year round on 265 70 17 sl load tires. Falken wildpeak. I don’t want to run them higher because it will be a stiffer ride.

for off roading I go down to 15 psi. Doesn’t matter if it’s snow, sand, rocks, or gravel roads.

35k miles so far and they are wearing down evenly.

I carry a vair 88p compressor with me and it takes about 2.5-3 min per tire to pump back up.

 

I think most people who off road and or mess with their tires carry or have some form of a compressor, air down kits and good gauges in their truck. I do.

Even if one doesn’t off-road, compressor and a good gauge surely isn’t a bad thing to have with you in general I’d imagine

 

Chalk test for a baseline.

Adjust for loads.

Adjust for terrain conditions.

Have tire deflators and on board air. Quick and easy changes.

 

Door jamb +2 psi

Add some add’l pressure in rear if towing the boat a significant distance.

 

I have a crappy one behind the seat but I barely use it. I usually just hit a pay machine at a gas station after I come down out of the woods.

 

I'm too lazy to do the chalk test so I do the "pull into the garage and the tires get covered in dust" test. Looked even enough so I left them where they were at, which is about 33 all around.

 

I just did a chalk test for the first time and I'm glad I did as my pressures were too high. Previously, I'd just been running (for a short time) what the tire shop recommended. Now that I fairly significantly dropped the pressures it rides a little softer and and my tires should wear more evenly and last longer. When I go offroad I'll still air down. And when I haul anything significant I'll up the pressures guided based on another chalk test (I think one test should give me an idea of a good place to be for future loads, I don't plan to test every single time).

 

What tires are you running and at what pressure? I recently put 235/85/16 Cooper STMaxx's on my truck and I am still trying to find the right psi. After reading this forum I think 44psi is way to high. I am going to try 35psi and chalk them and see how they feel.

 

I go by wear, and recommended pressure

 

i aim for 32 psi, but i jsut use the regulator that comes on the gas station air machines so not sure if that's super accurate

 

If specific air pressure numbers are important to you, over actual chalk/wear check, then I would suggest ordering yourself a high quality pressure gauge.

Like owning a torque wrench, every man should own a high quality air pressure gauge (or three).

 

I use this

 

We’re in similar situations actually. 255/85R16 Yokohama Geolandar MTs for me. I was originally somewhere around 44 like you. I had a hunch this was too high so dropped to 40psi. Then after the chalk test I ended up with 39F/33R. This was with only me in the cab and my “recovery” box in the bed which weighs probably 50lbs. And I think I was near a full tank. When we go camping next time I’ll do it again and suspect I’ll want to up my rear pressures to accommodate for all the supplies as for 2 people and a dog we travel fairly heavy.

I did the test real quick as I was short on time so I’d actually like to go back and try to dial it in a little more / confirm my findings.
