Co2 On Board Air systems from Instant Air Supply!

Have used my buddies Co2 for tires before and it's worked great. Multiple tire fills(on 2 rigs) off of one tank fill. Depending on your setupyou may have to watch out for developing frost on the connections.

 

I would make your own. I did a nice 20lb setup for about $250. Before you buy or build a CO2 setup, look for places to fill around you. A lot of places do tank exchange and no fill. 2 cents

 

Thats true found one place close to me cost me like $25. I prefer aluminum over steel and trying to find a tank for a decent price can be a challenge.

 

You can always check grow stores, some will carry and fill Co2 tanks. Kinda depends on which state you're in for the grow stores though
