Tire Chalk Test

["J"]

First I’ve heard of this. Seems pretty cut and dry. I wonder if it’d work on y’all’s trailer tires as well?

That is how I came up with pressure for my wife's jeep. Run 32psi on 35" tires

Stock tires? And what’s on the pressure on door frame.

This is a must do for any tire if you want it to wear correctly. I have run different load range E' anywhere from 45-65psi unloaded. It took forever to get the pressure just right with rhe 33's on my XJ while in college. So much so that campus police inquired while under the convo lol.

I have always found it hard to believe that tire shops didn't do this. I've never used chalk but kind do the same thing with water.

I used to auto cross and it's a great way to check pressures AND camber.

No one size bigger and door frame says 37, but I never go by that, Chalk ultra r always. Now if on my truck and I am hauling or towing I go with what the tire says.

Awesome. Thanks, J. My F150 is due for a new set of BFG's and I'll definitely be implementing this chalk test technique.

When I was racing, that’s the we did it. Chalk the tires an take a hot lap.

I was surprised to see the video, like I said in the original post, I’d never seen or heard about this before.
