Ok, this may be a stupid question, but bear with me. I am wondering if you could use one of the paint ball CO2 refillable tanks as an option for airing back up after a trail ride, or as an emergency option to fill a tire. If you put the right adapters on them do they have enough pressure to fill a tire? Would it be safe? I came across a 1 1/4 pound CO2 cylinder and thought that it would be a great, small option that could mount to the roll bar. I know others are using 5, 7, and 10lb tanks on their rigs. Supposedly the 10lb tank has enough CO2 to fill up to 30 tires (depending on tire size). So would the 1 1/4lb tank fill 3-4 tires? In theory it seems to make sense, but I just don't have enough experience to know if it would work. Any thoughts?

 

The only insight I have to offer is try it out!

Let some air out of a tire and give it a shot. Worst case scenario, you have to use a compressor and you're out a few bucks on the fitting?

If you do, let us know... Its a great idea in theory

I dont believe you will be all that happy with the 20oz setup. I highly doubt you will get 4 filled up unless you were sitting at 20psi and wanted to go to 30psi, and if that's the case, might as well just drive to the gas station

 

If you already have a paint ball CO2 tank, mod it up and give it a try.
THEN let us know how it works.

Good idea though.

 

For trail use it is best to have 5lb tank or the 10lb tank (depends on tire sizes). Anything smaller than 5lb tank will require you to do refill after every trip. Plus some refill station have a flat fee refill rate range from $8-15 for 5-15lb tanks for the same price.

I have a Paintball CO2 cylinder tank stored in my car(sedan) as a emergency air source in case I get a flat.

 

I was thinking of doing the same thing but through discussion with a local paintball field (old buddy of mine) there's not enough volume in a small CO2 tank to fill more than a tire or two

I have a really small, fiber high pressure tank that holds 4500psi of compressed air and with that I would be lucky to get 4 tires filled, once. Kind of a PITA to refill every time.

I've been thinking of getting my hands on stubby scuba tank and making up a regulator for it. You would get a few fills out of that. Or go big and buy a powertank.

 

You can put together a DIY 10lb tank setup for less than $130 dls plus shipping.

New 10 LB aluminum co2 tank on ebay $73
Hyperflo Co2 Regulator Wheelersoffroad.com $38
25ft reinforced Pneumatic hose harborfreight.com $9
Brass Quick Coupler kit ebay Set $4
Tire inflator chuck $3

Optional: Fire extinguisher mounting bracket ebay $35. There are several other cheap ways to mount the tank.

I have two of these and they work just fine.

It will be a pain in the butt to fill that smaller tank after each use.

 

Think I will give it a shot and see how it goes. I will post pics (if it works). Either way, I will let you know.

 

id recommend a carbon fiber pb tank, its compressed air as opposed to co2 and the average one is 68ci @ 4500psi, however thats 160 so you cold just buy a normal compresser

After years of using compressor setups my very first use of a CO2 tank to air up 4 35" tires was a moment of clarity.

Don't get anything less than a 5lb tank. I chose the 5lb setup (actually I have dual 5lb tanks, mounted to the rear bars under the hardtop) because it didn't infringe on space, and is brilliantly accessible for use.
And get a tire inflator with gauge, it's just that much more fun.
