How low can the tires go before I run into a possibly dangerous stiuation? I have 33x11.5 on a 15x8 wheel. Im always afraid of dropping my tires below 18PSI... can I go lower than that? and if so, how much?

 

til the bead comes off....


I regularly go down to 10 and below when I go play.

 

just have to worry about the low psi when turning because it will push the tire off the bead. I run 15 -12 in sand and 10-below for snow.

 

Ditto, im usualy at 8-9 when offroad

 

10psi easy. Lower if you want, but 10psi is pretty safe.

I use to drive home at 60mph+ over 50 miles with 18psi all the time.

 

i used to drop my 33x12.5x15 MTR's down to about 12 on some 15x10's. i would only go to about 15 when i had 15x8s.

 

getting a 'flat' is not an option, so about 10 PSI?

 

number 1: what are you doing to require you to run it so low in the first place? on the street ontop of packed snow? I generally am down in the high teens for street snow use. Quite a bit lower when I'm out playing in the real deep stuff and trail riding with snow or even without snow.

 

had my 12.5" wide tires on 10" wide wheels at 8 psi all summer at the dunes.. no issues

 

I ran some 33x10.5 Thornbirds between 8 - 12 psi when the center tread was slick til I could get some new tires.

 

ya what are you airing down for ?

 

for running over little children....... maybe not so much

 

ya i usually run 10-12 in the sand

 

ive run my bfgs down to 2-3 psi, took em on the freeway at 80 mph with that psi too... only bad thing that ive heard about the bfgs and airing down is that they have a weak sideway and that potentially could be bad.. but they have held up pretty well.

 

wow are you serious? you went 80 MPH with 2-3 PSI??

 

yesssir!!! i went out to this mountain at 3 am to pull my buddys yota out cause he got stuck 3 days ago, the place was a total mess so i aired down... and by the time we finally got it out it was almost 7 o clock and the ticket office for the OSU football game was about to open!! so we had to mob back 35 miles!!

 

so who here is going to explain why going 80 MPH on 2-3 PSI is a bad idea?

 

lmao, i run what ever pressure the low pressure indicator turns off at, all the time, no matter what conditions... a lot of it is because i have nitrogen, so when i want to air back up, i don't want to put air in...

 

uhh... maybe you could... mr. mallcrawler with a lift!!!

 

^^Mr. "my axle isn't centered to the truck"...

Mr. "I can't figure out why cops keep pulling me over for the same thing"...



That kind of psi at that kind of speed without locks....is just stupid. Don't matter who you are or where your goin'...just plain stupid. You were lucky the sidewalls didn't seperate from the tread...just stupid. Right there next to lincoln locked DD's.

 

umm.. i have beadlocks!!

 

The PSI range is on the side wall of the tire.

 

yah. thats what im worried about.. time to ditch the bfgs!!!

 

Nope sure can't that's why i was having some else do it.

 

I run about 78% nitrogen. It is free and I can refill with it anywhere on Earth.
Just another reason I think paying for nitrogen is stupid, nobody wants to air down and lose their precious nitrogen that they paid for. lol
