Tried doing a chalk test, seemed simple. I am running Falken MT01 mud terrains in 35x12.5x17 on factory rims at 30psi on a hot day. Ran the test in adjacent lot after work.

At 30psi I am still over inflated, as the chalk left of the pavement is about an inch or two narrower than the measured width of my tire. I couldn’t tell with the first car length so I drove down a couple dozen parking spaces and had the result at the bottom picture. First ones are after one truck length

That’s because factory wheels are a bit skinny. Who cares. They will help keep the bead better when they’re skinny. I run 30 psi in my 37s on factory wheels. I didn’t do a chalk test. That’s too much work. :devil:

They actually look pretty good.

I like even tire wear. Tires be expensive
I got ya. Lol

I don’t think you’ll do much better than that with a mud tire. They won’t really sit level for a chalk test. They are built that way for noise, treadwear etc.
