I don't have beadlocks, so wouldn't 8 be to low anyways? I was thinking of just going to 20 or maybe 158 if you drive slow, 5 if you drive very slow, 4 if you are feeling lucky.
So if I just aired down to 15 psi, 4 miles going maybe 35 would be safe?Limit your speed to 20-25 mph and you can make it to the gas station with aired-down tires. You just want to avoid going fast enough that they would overheat and blow. I ran 8 psi quite a bit with 35's on my previous 8" wide non-beadlock wheels and I never lost a bead. I wouldn't try 8 psi with 10" wide wheels though.
Possibly though few experienced offroaders consider anything 15 psi or higher to be aired down. It's when you get down to slightly lower air pressures like 12 psi where you start really seeing the benefits of an aired down tire.So if I just aired down to 15 psi, 4 miles going maybe 35 would be safe?
Not that anyone should, but I have successfully driven both my non-beadlocked 33s and 35s aired down to 8psi at highway speeds multiple times over longer distances between trailheads. I don't really give it a second thought.
I am by no means an "experienced off-roader" but have driven several miles at 15 PSI on several occasions. What I found was the the ride was quite pleasant.
The best person to ask is the tire manufacturer or retail tire shop.
Ya, first person I'd ask about tire pressures for sure. Those guys that just put my new tires at 52 psi because it says so on the sidewall.The best person to ask is the tire manufacturer or retail tire shop.
I plan on getting the ARB single very soonSpeed is the big factor aired down. Speed on a flat tire builds heat leading to sidewall damage and a shredded tire. The best person to ask is the tire manufacturer or retail tire shop.
Aired down is meant for crawling around. If you don't see a sidewall bulge, which is what causes a heat build up, you are likely OK. TJs are pretty light weight and 35s are massive on them. The lighter the vehicle, bigger the tire, the lower you can go.
Why not buy an air compressor and be safe?
Your tires are living on borrowed time by doing that. It's not losing a bead that is the issue, that's nothing and easily fixed if it happens. It's that the tires run significantly hotter when aired down that far and they can fail from the heat when run at such speeds when aired down to a lower air pressure like 8 psi.I drive around town on 8 psi when im too lazy to air back up. Not that I can say this is the smartest or the safest but i've gone probably 50 or 55 on 8 PSI for short distances and never had an issue. A lot of people are so concerned about debeading their tires but if you ask around its actually pretty rare. That usually happens on the rocks or in the woods where it can get pinched/caught. You will not debead your tire just driving on the road unless maybe your air pressure is non-existent.
