Cold weather, daily tire pressures

I'm curious about tire sizes and pressures. I have 285/75/16 KO2's.

My average temps are in the 40's.

What PSI are you guys adjusting to?

My truck says 35psi leaving the garage and 11 miles later 38psi. They seem to be wearing great.

Most of my miles are highway, 16 MPG average.

 

Variety of answers you will get here, lots of factors at play, weather, temps, load, type of tyre, etc.

Personally I run 34x10.5 R17, and am fully armoured up with a drifter on the back and ride at 40 in the rear and 37 in the front. Checked the tyres with chalk to see the wear pattern and adjusted accordingly. Seems to be where i need to site. So i set them cold at 35 in the front and 37 in the rear. They warm up to where i want them.

 

Every 11 degrees temp change adds or takes away one psi. So if it were 20 degrees at daylight and 50 degrees at 2pm, your tires will gain three psi. If you are currently on the 40's check and air up your tires to proper pressure at 40 degrees. If it goes up or down a few psi either way that's ok and will not mess with tire wear.

 

pfft, its the proper way,

 

That’s a lot of air in those tires...

 

You think so? 95% of my driving is highway.

 

I'm not too concerned about how ya'll determine what psi to run.

Im just interested in the psi, average temps and tire sizes you all are running in a daily driving situation.

 

I just want to learn stuff from you man. You always come with the knowledge. I had never heard this before.

 

When colder temps hit I dropped to 30-31 psi. Mileage dropped from 15-16 mpg to 11-12. Filled up t 38 psi and mileage is back up. Granted on 33x12.5x20s.

 

Now that the temperature is finally starting to drop in the northeast. What tire pressure is everyone running? I am currently running General AT2s (265/75/16).

 

Average temperature?
What PSI do I adjust to?

I fill my LT265/75/16s to 1,978 lbs inflated load capacity @ 37 PSI cold.
It's common around here to have 40° degree temperature shifts between morning and afternoon; or a 4 PSI variation. My tires heat up 3 PSI when driven.
So, I could leave in the morning with 37 PSI and come home with 44 PSI.
With LTs, better to be 'overinflated' than 'underinflated'.

Just a FYI...
P and euro metric are inflated to 2,149 lbs.
LTs are inflated to 1,954 lbs.
An LT285/75/16 has an inflated load of 1,978 lbs @ 31 PSI.

 

its been in the low 40s. but, within the next couple of weeks it will be in the 20s-30s. when I checked this morning, I had 32/33 PSI.

 

I keep my 265/75/16 Duratracs at about 30 psi., same as the door jam. I also have the (4) psi readings on my little screen behind the steering wheel. Always like to keep an eye on them!

In the winter, I'll bump them up to about 32 psi, just because
