Yeah, I agree. A 5 gallon tank only brings one tire (33x12.50r15) on my truck up 17psi. Basically, a 5 gallon tank at 115psi only brings one tire up from trail pressure to highway pressure.
The reason I have the tank is so I can put a tire back on the rim. If you've ever seen a person try to get a tire back on the rim with only a York and no tank you haven't lived yet. /forums/images/graemlins/rotfl.gif It's a lot of work because even the "big" York that flows 8cfm isn't enough unless you get real lucky.
"I don't know why it isn't going on..."
"Well, first of all, you need to get the weight off the tire."
"Can I borrow your Hi-Lift?"
"Yeap."
I go grab my bottle of Windex after I use my Hi-Lift on his rig.
He clinks around spending five minutes trying to get it to go back on with his buddy revving the engine to get more volume.
Nobody knows why I have the Windex bottle and no one asks.
He gets frustrated and remembers some people use ratchet straps to squish the tire to push out the beads.
"Can I borrow a ratchet strap?"
"Yeap. Just don't get it muddy." I try not to grin after that one.
He sticks it on there and gets mad at it because it doesn't work.
"Do you need some help?"
"Yes, please."
I remove the core from the valve stem, dump some Windex on the beads, stick the chuck on the valve stem, and pop the bead on. I pull the chuck off and let the air out while he says "hurry up and put the core back in" and I'm like "...?" turns out he thinks the tire is going to "fall off" the bead. I yank my ratchet strap off, put the core back in, and let him put air back in the tire while I retrieved my Hi-Lift. Some people's parents just shouldn't let their kids have their Visa and allow them to torment Onboardair.com.
