Airing down your tires

[teebes]

On a slight tangent... I just stumbled across these Monster valves (probably cause I haven't looked into powertanks that much before). Kinda pricey but sure would save some time for those with the other goodies.

Monster Valves are oversized, light weight yet strong valve stems that you install as a second stem to your wheel. Made from 7018 alumnum, they are the FASTEST tire deflation product on the market. Imagine airing down a 39.5x13.50 tire down 30 PSI in 30 seconds. This kit also includes a Monster Chuck which, when used with a Power Tank, will inflate that same tire in 50-60 seconds. And they are EASY to install into steel or aluminum wheels. Just drill a 7/16" hole, tap 1/4" NPT threads, and screw them in. Done.
With an aluminum body and collar and brass cap the total weight of each valve is a mere 1.1 oz. Due to its construction it is 5 times stiffer than a standard metal valve.

Any one of you engineering fabricator guys thought of doing a mock up like on some military vehicles where you can air up or down with out getting out of the truck?

You pretty much have to have portal axles for that...

Or no drive axle (such as truck trailers).

IF your looking at getting a power tank.. You should check out the Source Kits. We sell both, and the Powertanks definitely look cooler, but the brackets on the Source kits are allot better, and the kit itself functions the same for about half the price.

This is true... or the front end of a 2WD truck... I should have probably stated that, but figured it was a moot point because of the off-roadyness of the conversation...

There are vhehicles that have it and are four by fours like H1's.

H1s have portal axles...

Well, I thought I had remembered seeing an outside-the-tire system... after a little googling: yep:



Seen here on both front and rear:



So it's possible... but I do wonder about it's possibility of getting snagged on a passing rock or tree...

... it's possibility of getting snagged on a passing rock or tree...

Agreed. That concept could ONLY work on an open trail or sandy rally course. My rims have enough rock rash to convince me I can't even leave the Stauns on after they do their job. I added some captive units (No-Loss Valve Caps) so it's easier to get going again after airing down.

the trail we were on this weekend, we only had a matter of inches between the trucks and the trees.

[The Roadie]

...inches between the trucks and the trees.

One benefit of having a group of identical vehicles is that if the first one gets through, the rest "should" be able to follow. If you have a wiener dog in the group, send them first, though.

[foosh]

Roadie... If I have learned anything offroading and driving ingeneral, its not always so simple as if he gets through i will, or visa versa as I'm sure you know. I've seen people go through mud and get stuck then a different driver do the same and get through (Irishboy02). And in the sand I've driven right through some areas that others get stuck 3 times... (Irishboy02). So a good amount of what you can do is in the tires and torque, while the rest, the last 25% and sometimes the most important is in the skill. I'm sure you see the same thing... someone trying to go to fast over rocks and gets hung up because they don't spend enough time to get a line, while you just slowly coast through.

[The Roadie]

Agreed. I was mostly thinking of width. Where we can go due to narrow width and tight turning radius, an H1 would often be denied.

[foosh]

Very true, my one buddy who is always vehicle swapping tends to get a bunch of fullsize chevys and his stuff wouldn't have made it through a bunch of the trails i've done recently, a k5 on 35's = no turning radius and way wide, 1500 blazer= better turning radius, still not skinny enough... the only thing that would make it through the trails we do are jeepers and short bed s10's.
