I've heard of the propane trick used to set the bead of a flat tubeless tire. In that case the propane is "floated" into the deflated tire, and when ignited the (hopefully) small explosion fills the tire quickly enough that it sets the bead.

A good cinch strap around the circumference of the tire and cranked tight will also work to force the bead onto the rim so that the tire can be inflated conventionally.

After the bead is set the tire is inflated with air, not more propane.

It seems like a bad idea to use propane to fill a sealed, but low on pressure tire!

I have no idea what propane gas might do to the rubber in a tire. Other than that it would probably work OK to inflate you tires. I would just use straight propane and no air. Pure propane will not ignite, it needs oxygen and adding air will provide that. I also have no idea where an ignition source might come from inside of wheel and tire but if there was one it would be exciting.

I shared my good experience with a ViAir 12VDC pump. If you want fast, cheap and light, watch the following video. I have not tried it yet, but will start carrying the necessary components as a backup, "just in case".

If you want to know how to use propane or gasoline to seat a tire, ask DK. I had no idea he could move that fast. :O

The tire belonged to a fellow Nomad and none of us had used that trick. It took a few tries but worked when all else failed. Kudos to the Fast Mover.

That was fun... I had read about Mexicans doing it in the old days (from Mike McMahan maybe?)... a little gasoline and a spark... woosh, tire reset on the bead! I was very pleased to get it to work. It would have been fun to have that recorded for Your Tube. I did film when 'hbmurphy' tried doing it first. If I can find that, I will post it here... success:

More questions regarding charger vs trickle charger


Thanks again to all who contributed their ideas/experiences/recommendations.

Just picked up this model at CostCo, $75. Reviewed here:
http://www.amazon.com/PowerStation-PSX-3-Jumpstarter-Compres...

and here:

http://costcocouple.com/powerstation-psx3-portable-jumpstart...

Decided it was one of those "better to have/not need, than need/not have" items to carry in the truck. Or maybe it's a good excuse to go drive off-road to see how it performs...

Next question: trickle chargers.

I had previously purchased a DieHard battery charger/starter that runs off current, for use at home. Now I'm thinking I'll keep it, to use on the garaged car battery (set on trickle) while away for a period of time.

Has anyone done this while spending time between two locations? If you leave a car on trickle charge, is that better for the battery vs. not being driven/charged for long periods of time?

Great to have the air pump... but, it will be slow because it connects to the cigarette lighter... Everyone going to Baja should have an air pump, because deflating tires is the single best way to get unstuck or improve traction. A tire plug kit should go with you too, and you will need the pump to add air back after you plug the hole!

The 18 Amp Hour battery remains charged as long as it's plugged in to 110 but if you drive around with it in your car for more then a week it will not jump start a car with a dead battery or inflate a flat tire. I took mine back to Costco for this reason and they would not give refund because unit was not faulty. I just wasn't using it properly (ie: keeping itr plugged into 110)

Nope, this one does not have provision for operating from cigarette lighter. Just uses integral 18 amp battery (if it's charged; otherwise nada)

PSX3 compressor runs off internal 18Ah battery, not 12V


Dave K- I remembered your warning about this, and checked the manual at CostCo before buying this model.

The compressor runs off the internal 18 Ah battery, not via 12V. It is limited to 10 minutes run time, then a 10 minute cooling break. Not sure how long it will take to fill tires.

The 12V plug is to operate items that can run off 12V. You can also recharge the battery via the 12 volt connection from the car lighter outlet --> battery outlet, though that's not to exceed 2 hours. The preferred charging method is via AC.

Mainly I took a gamble on this because CostCo stands behind their products, and if anything doesn't work as promised, they will take it back and refund the cost.

Hmmm...well, most of my trips are a week or less. I'll charge it at home, let it sit for a week or three, and see how the charge holds up.

I'd be surprised if CostCo would not accept a return. They say "satisfaction guaranteed," but I can see why they might question the reason in a case like this, suspecting you were basically renting it for a trip.

(They changed their policy on big screen TVs several years ago when, during playoff/SuperBowl weeks, they realized people were purchasing big screens for game days, then returning them afterwards.)

When I have to change the air in one of my tires, I let all the old air out, move the tire at least 100 feet away, so no old air gets back in, and put new air in.....

I attach this to a panel, for use when camping/parking for several days.

But it won't work inside a garage. So I have a DieHard 110 plugin trickle charger for extended absences.

Anyone else have experience with these scenarios?
