I am curious what is a good PSI to run on my Toyo MT 265/75/16 tires for daily Driving??

I went wheeling yesterday and brought my PSI down to 20 for the trails and neglected to notice what they were at before I aired them down (Wasnt thinking).

What is recommend to run on the roads?

Shouldnt the recomendation be written on the sidewall of the tire? Mayne a maximum preasre? So some below for harder tires and slighty better gas milage

Gee oh Dee

32ish

If it helps I run my BF Goodrich All Terrain LT265/75R16's at 60 PSI ... I took the max PSI and dropped 5 off of it.

And I am sure those wore funny as hell...32psi is what is recomended for any tire on an xj.

The Cherokee weighs under 4000 lbs so you don't need anymore than 32 psi, if you need that much.

I run 20 lbs in my 35x12.5 r15s unless I'm going to drive 200 miles or more one way then I go up to 24 lbs.

do you have LT or P tires? Big difference. You never need more then 35psi for an XJ, but if you have LT tires, running them at 35psi is running them half flat, no good. I'm running Toyo Open Country A/T P265/75R16 i run 40psi for daily driving, its a little bumpier, but i get better mpg.

Run 32 PSI in the tires, draw a line with crayon or paint pen across the outer part of the tread lugs of the tire width wise. Drive around for a few miles and check the line.

If it is gone or almost gone but worn evenly then you are at the correct pressure.
If the inner part of the line is worn more than the outer part then you are running too much pressure... deflate a few PSI and try again.
If the outer parts of the line are worn more than the middle you are running too little pressure... inflate the tire a few PSI and try again.

Not understanding what you are saying here. If I'm getting this right you're asking me if my tires are LT which stands for Light Truck or P metric sized tires. You then say that you never need more than 35 psi for a Cherokee, then state that you run 40 psi in your P265/75r16 Toyo ATs.
I run 35x12.5 r15s on my Cherokee, no LT and no P metric. I'm running Toyo ATs size LT265/70r17s on my Ford pickup and I run them at 35 psi. and they do fine and they aren't half flat.

I am confused as well with his comment my 285/75R16 load range D LT were run at 32PSI there entire life including on my ranger. they were not half flat. just because the sidewall says max inflation of XXX PSI doesn't mean thats what you inflate the tires up to.

Most tires tell you XXXX # of pounds at XXPSI max. What that means is... Lets say if the tire is rated at 1500 lbs at 40PSI that means 4 tires can support 6000 lbs at 40PSI. If you run 40PSI on a 3500 lb rig the tires will wear faster in the middle because there isn't enough weight for the rated pressure.

I lean towards Rock Toy's comment:

"I run 20 lbs in my 35x12.5 r15s unless I'm going to drive 200 miles or more one way then I go up to 24 lbs."

With the pot holes and washboard on my gravel road running at 28 I won't overheat the tires, (by over-flexing)(), or damage the rim, but still run a little smoother, around here.
When I work I'm loaded (or overloaded), with tools doing 1000 mi of freeway I'll go to 38. Somehow my tire wear comes out OK without running 32. If I don't get more work I'll need to go with Biohazed to make up for it!

Thanks for the tip Razor

I run 30 lbs in my 32x11.50's

Im just gonna drive it on the roads around where I live for daily driving with 30psi ish in the tires. With doing more research on the web this seems to be the good number to run in the tires.
