Adjust air pressure by using the chalk test

[@GunNut37086]

I have the same Toyos on mine, but with 15x10 wheels and I have to drop mine to 28 psi to get a flat wear pattern.

[@MyTrucker619]

After continuing adjusting them mine are at 28 too makes a full contact to the ground... My problem is my Jeep says the air is too low and throws the low tire light

@@MyTrucker619 I had to buy a flash tool to fix the ECM when I changed tire size anyway. It let me adjust the threshold on the tire pressure warning.

How much does the air pressure increase with the heat build up if driving? Should it be set a bit low to allow for that?

[@MyTrucker619]

Generally only a few PSI

I've heard that why you should do the chalk test when tires are warm.

[@bajamedic]

You need to turn it down like 5 levels with the red.

[@MyTrucker619]

I’ll be switching it up again shortly... I’m getting bored of the red too... I’m thinking Bronze for the wheels

[@gregwilson5393]

you should do this with warm tires.

What load range are they? 8 or 10 ply side walls?

[@MyTrucker619]
