Tire pressure too low or too high? W/ pic

I have about 150 miles or so on my Duratracs and have been running them around 30 psi. I'm trying to determine if this is too high or too low. I did the chalk test and the chalk runs all the way across the tire to the dark lines on the outside of the tire. Do I need to run lower? My dad was arguing that my pressure is too low, I said too high. All 4 tires look like this. Thanks

I like running my tires at 26psi. I think you might be a bit high at 30. How does it ride?

It seems to ride fine. Maybe it's a bit rough but it's a new suspension which was done at the same time so hard to gauge which is the result of which. I'll drop the psi some and do some more tests.

I'm not familiar with those tires, what load rating are they? I feel 26-28 would be normal for our YJ's. If they are E rated the tire will run harsher because of stiffer sidewalls, if D rated at the pressure I mentioned you should have a much better ride.

They are Goodyear Duratrac Load C. I'm for sure going to air down to high 20s and will redo the chalk test. But first, camping trip! Unfortunately sans Jeep...
