Tire pressure for mudding?

Just curious what pressure you guys leave in your tires when you are mudding. I normally keep my 285/75/16's at about 30 - 32 normally, and had them at 20 today when I was mudding. I had the seal on one of them break today, when I slid into a large mud hole. Is 20 too low, high, or just right? I will be getting 35 x 12.5's soon, so curious on those as well.

It may have been just bad luck that it came off the rim. I slid into the side of a large mud hole, and then had to be towed out, which took many tries. Could have just been the towing and spinning of the tire that caused it to break.

Re: Tire pressure for mudding?

In my experience you don't air down for mud. Just keep them at whatever you run for the road. You don't want the tire to break a bead or slide on the rim like you had happen.

Now, I do know guys in New Zealand who actually air down, but their mudding is a bit slower and more technical. Climbing ruts and all that, where the larger contact patch would be good. For speed though, like your sig pic[img]images/graemlins/cool.gif[/img], keep them at the highway pressure.

Ever see those Camel Trophy Land Rovers? They usually had highway or HIGHER air pressures in them.

Re: Tire pressure for mudding?

i run 32-35 psi on my 35's and that seems to work fine. except for climbing out of ruts, i dont think the lower pressure would help, because you want to force the lugs to grab the bottom, not deflect away from it, as you spin them quickly. plus, an aired down 35 might as well be a 33 in the mud as far as clearance... i'd keep them at 28+ on a fullsize, but obviously for a Zuk or CJ3 you could get away with 20 or lower depending on the tire.

Re: Tire pressure for mudding?

Yeah i'm thinking that I will always keep my tires at about 32 psi, mudding and on road.

Re: Tire pressure for mudding?

I was running 20 psi in my 33" boggers on my 89 yj jeep and I had the tire come off the rim twice so screw that, its up to 30!

Well here it is...

My truck deep in mud, about 1.6MB Picture

This picture is probably about 1.6MB, so it may take a few to show, if you have a slow connection. You need to click on the link, the one below is my signature. This is also on my friends website, so if he moves it, it may disappear. If so, i'll throw it on geocities.

Re: Tire pressure for mudding?

Oh, messy.[img]images/graemlins/cool.gif[/img] Things like that and my low cash flow are why I tend to be a wuss when it comes to large bodies of muck and water. Never know how deep they are or what's in them.[img]images/graemlins/tongue.gif[/img]

With tires of different sizes than my vehicles came with, I just do the chalk/water test till I have the whole tread on the ground. Never had a problem with it.[img]images/graemlins/cool.gif[/img]

Re: Tire pressure for mudding?

That is a deep puddle but it definately doesn't look like it is, thanks for proving it! Any chances of trying that hole again? Does the other jeepers/trucks make it thru it? cool pic...
