This is why I don't recommend the chalk test. 40 PSI is WWWAAAAYYYYYYY to high for 35" tires.

What do you recommend? Chalk seems logical to me.

Friends don't let friends chrome out their rig...

Around 26 PSI for 35s, I run 28 PSI for 33s.

Larger tires require less pressure. The chalk test doesn't work because our oversized tires will never run a perfect tread pattern and because most people don't know how to interpret the chalk. It's funny that you interpreted the chalk as no enough pressure most people go way to low. For offroad purposes we run wide tires on narrower wheels, which means at street pressure you'll never get a full tread contact.

Your jeep must ride like a brick. Larger/offroad tires have stiff sidewalls, our jeeps just don't weigh enough to justify 40 PSI. If you drop your pressure down I'm sure you'll find your ride gets WAY better.

I run 20 psi in the back and 24 psi in the front on my 74 Cj5 with 35" MTR's... Jeep is way too light to effect those 3ply side-walls. been running 35's that way since 01... had good luck and a way better ride.

man at 40 psi mine would bounce from lane to lane. 26 psi on 35"s with a 8" wide rim. C rated MTRk. wear is good @ 24k right now. at 40 psi i would have worn the centers off by now.

I was looking at that compressor as well. Si how will you be wiring the pressure switch to trigger a relay on the power? Also where did you get the tank and how much?

I was thinking of mounting it all on my roof rack in a diamond plate box with some sort of isolation system...
