I'd feel so bad for the guy, I'd probably volunteer one of my cylindars!

 

I've done it a few times with my Specialized bicycle pump. I guess you guys haven't tried it yet. Airing up from 15-17 lbs - 35 lbs is easier than you guys might think. It also probably makes a difference with the quality pump you have though.

I picked up a $10 Target brand pump that you hook-up to a cigarette lighter. This was around Christmas time, so it even came in a Christmas packaging box. I used it a month ago at the desert to air up 4, 32" tires and 4, 31" tires with no problem. Aired all 8 up to 36 psi. I made sure I gave it 5 minutes to cool down before airing up the 2nd vehicle though. Quite surprisingly, it worked great!

 

I actually pumped up a tire for a lady at work. She came out and her tire was flat. I had the old model of that pump in my truck because I was bike commuting and left it there. I just got the tire pumped up enough for her to drive to the gas station when the hose nipple at the bottom of the pump broke off and shot across the parking lot. To Serfas' credit they liked the story enough that they sent me a new pump!! The new pump has a metal cylinder with a beefier connection. If you ever use a bike pump take it slow. I think my agro approach created too much heat which caused the failure.


I was thinking though ( :pat: ) what if you had a hand operated pump with a much larger cylinder. Heck, we're only going to put about 35 psi in these tires right? The problem with the bike pump is that the pump cylinder is so small. Why wouldn't that work? It'd be a whole lot simpler than compressors and tanks!

 

Ummmm driving a short distance slowly while aired down is not THAT bad...Yeesh!

Good article on various methods - I think this is descrobed in there...

After several google search attempts I couldn't find pump like I'm picturing. There are some high volume pumps for inflatable boats but for very low psi applications. There are some "high volume" foot pumps for cars. But, they're not really very high volume. Looks like I'll need to build a prototype!

Nice links tc!

 

The "huffer" I think it's called obviously wasn't in that article ... maybe I read it in "The Four Wheeler's Bible" ... If so, maybe I can scan the page it's on and post it...

I found those little cigarette lighter 300psi air pumps on sale at a ranch store for $6 each. I bought three of 'em, cause I got 3 cig lighter outlets in the Tacoma! One of 'em runs slower than the others...but they'll air up all four tires from 15 to 35 in 15 minutes or so. Everyone makes fun of me, but hey, I can take it!

 

We had a guy who came out on WATTORA events for a while, who aired up that way. He had little, tiny tires, like 31x9.5, but he could air all four of his up with the hand pump faster than my old QuickAirII would do my 35x12.5's, with both going 15 to 35 PSI.

It was a riot to watch...

 

I guess one other problem might be getting grunge in your cylinder. I like to make sure my heads are clean around the plug ports before I change plugs, especially when the plugs are hard to reach/see. Interesting idea, though.
