tire pressure without beadlocks

First time I had mine offroad I was like wtf. I paid this much for this POS. I was at 38 plus a couple from the highway and hot day. Had to get speed up to smooth it out. I wasn't impressed at all.

So ya, knocking some air out makes a huge difference.

exactly, the OP will have the same experience I’m sure, airing down is necessary and not just a few lbs or the truck feels almost unsafe until you get used to rear having a temporary mind of it’s own
where do you drive off road on the island?

Up in behind Chehalis and south of Cowichan toward Port Renfrew. Planning on some trips to the north west end of the island and some other places north and west of Campbell Rvr. too.

next time i make a trip from vancouver i’ll see if you’re up for off roading

Years ago I was a member of the Campo Border Riders 4X4 Club in San Diego. With no bead locks, we would go down to around 15-20 pounds on hard terrain. In the sand dunes, we would go down to about 6 pounds. After running a while on the hot desert sands the pressure would build back up to 20 pounds or more. Either a visual inspection or notice that you were losing traction would dictate lowering pressure again. We would occasionally lose a bead and all pressure but that was very rare.

I had an auto air conditioning compressor that ran off a pulley (belt). I'm interested to know what kind of air compressor you guys are using and how long it takes to air your tires up with it. My auto compressor was as good as a compressor at a service station.

Have you noted any accelerated tire wear running these pressures full time? I’m think of running 32 cold psi on rough dirt/caliche roads and interstate highways at High speed. I don’t do much deep mud or heavy rock or soft sand. I’m looking for a “catch all” psi.

take a grease pencil and draw a line across your tire from side to side.

set your tires to your desired pressure.

Drive around the block. If the center of the tire still shows the line, your pressure is too low. If it still shows on the outer sections of the tread but is gone in the middle, your pressure is set too high.

Play with the pressure until the line wears evenly. That will be your "perfect pressure" for tire longevity.

Great. Same, I was up east Harrison last summer in my SUV. Couldn't make it all the way through to Boston bar. Will redo the trip in the rap. Looking at a trip up West Harrison to Pemberton too.

you can geta a really small compressor that plugs into your lighter socket

I use the ARB twin, it works great.

Viair 400P here. Also works great!

Normal speed stuff 18-20. Crawling around on rocks, or rough trails, I air down until my knee will put a pretty good dent in the tire, somewhat for traction, but mostly comfort. Probably 10-12.

Go to pep boys, or whatever, and grab a cheapo compressor for $30 anyway. They are handy to have around. Tire plug kit is good to keep around also.
