Tire pressure wheeling
So i have BF goodrich all terrain tires. I think they r 32's....basicly stock. My question is that I wheel at 35psi. I dont do much if any climbing besides large rocks on the trail and mostly water/mud.

A friend said I should deflate the tires a bit for better traction. Did some research and found 20lbs was recomended.

My worry is, at 20psi wont I pop/bust a bead?

What is suggested from people who actully wheel?

I've got 33" BFG MT's on a JK Unlimited. This weekend was the first time I was able to air down since I finally got my compressor. I dropped em right down to about 16psi and had no issues. You can see from the pic the kind of terrain I was running on. Getting tire pressure this low made a HUGE difference in traction, and I had no problems getting through some tough spots.

you will not pop a bead at 20psi.

I usually run at 18 on the trail and have never lost a bead.

I've had my bfg at's down to 10 lbs wheeling

Last time, I wheeled on rocks, I had it down to 15-16psi with no issues. There was someone on the trail with me who had it down to 12psi with no issues.

I have the 285 x 75 x16 Duratracs

i drop to 16-18PSI while out here in Colorado.

My question is what is the max speed or distance to drive on low tires?

to explain more...i forgot my compressor at home and though there would be a gas station at the other end...turned out having to drive down a long (10miles) windy road back to the highway...and having to drive highway speeds for about 2 miles until i finally found a gas station. I was pretty worried about taking turns at any speed over 15mph. How bad is this on my wheels? thanks guys! Yes, im a newbie

i go 15-20 on trails. i got a flat once (which i didn't know until i got home) and it held up at 10psi during a 15 mile freeway trip. The next day, it was reading 0psi and i was still able to drive it a block away to air up (not recommended) but it holds.

I have 35x12.50x17 Cooper Muds that I run at 28 PSI in town - on the trail I air down to 17 PSI. I could proably go down to 15 PSI no issues. My tires are a 4ply side wall, but anoter guy I wheel with has a 3 ply sidewall and his squat ALOT more at 17 PSI than mine but he hasnt lost a bead ever.

Now, bone time before I got my AIVAIR compressor I rode all the way from Florence, Az to Tucson Az @ 17 PSI. 55-65 MPH....

Ok so I took a look today. They are 32" BF Goodrich baja champion all terrain T/A's. LT 265/70R 17's. 121/118R

So at 20psi I should be good?

bushey 07-29-2013 07:30 PM

Total noob question, but- do you loose any ground clearance when airing down to 20 psi or so?

RRTRI 07-29-2013 07:55 PM

I ran my Kelly Safaris (315) at 16 PSI this past weekend. Never even close to an issue at that pressure.
