Anyone used one of these CO2 tanks? Im looking for a cost effective option and hoping for some input. Well its not that cost effective but its cheaper than a compressor.

i dont know if you have a harbor freight where your at but they are having a sale right now. I recently bought a 12v 150 psi portable compressor that connects to your battery. It gets a little hot but it works and you cant beat the price; less than 50 bucks.
works for me.

 

After having used nitrogen for years, about 10 now,(used it in our racecar tires becaus it doesn't expand as fast) then in my off road vehicles. I switched to
C02 about a year ago. It works very well, It's cheaper than nitrogen ($7.00 for a 10lb tank) and it has more volume in the same size tank. It's portable so you can take it with you as needed, I.E help out your buddy with a blown bead bloking the trail ahead of you You can also use it to run air tools. You can also easily swap it from vehicle to vehicle, unlike mounted compressors. It will inflate a 35 inch tire from 5 psi to 32 psi in about 1/4 the time of compressed air. One disadvantage, in freezing weather with a high flow rate, it does tend to freeze up sometimes ( not solid, just ices up). Also, instead of paying the high price of the modified regulators if you are handy you can drill them out yourself (which needs to be done to allow sufficient flow for large tires and air tools. BTW go with the aluminum tank, initial cost is a little more, but MUCH lighter than the steel. I also use it to power my air horns in my big Dodge.Good luck with whatever you choose.

 

You can make your own co2 tank for under $150. Any beverage supply or ebay will have a 5, 10 or 20 lb tank. Get a regulator at a welding supply shop.

 

I picked up one from there last week then went home and dropped down to about 20psi then back up to 35psi, I only played with 2 tires but they went pretty quick less then 5min a tire, I was happy with that. It did get a little hot. Are you going to hard mount yours?

 

How long does one tank last I mean like how many tire's and if you don't use it how long will it hold air.

 

a 20lb tank will do about 30-40 35" tires, maybe more.

 

I just bought a 12v compressor from Costco for $47. I have not used it yet

 

I used a power tank on my last rig and LOVE it. I have an idea for a mount where the stock muffler goes, but need to figure out a skid/safety solution first. I highly recommend Co2 over compressors.

 

The Superflow MV50 / Masterflow MF1050 are the best bang for the buck 12v compressors, imo. They're around $50 at some Pep Boys, and I heard they were selling them at Costco, but don't know that for sure. If you have to you can pick one up from Summit Racing for $70.

The Harbor Freight compressor is at least 30 seconds slower (measured) on a 32" rubi tire from 20-37PSI. . . though it's good for $50.

I've got the Superflow, a homemade "4air" setup, and I'll be building my own CO2 setup. . . mainly 'cause I like having as many options as possible.
