Portable air compressor

I'll second the Terrain Tamer Twin Cylinder.Mine cost $125 at the 4wd show last year - bought it to use in the shed and on the Xtrail, but tested it against my Blue Tongue 3 on my LandCruiser tyres and it was just as quick. Hope it goes as long as the Blue Tongue.

And when it comes to reseating tubeless tyres, how fast a compresser pumps doesn't have much to do with it. We reseat tubeless with any of the modern compressors. The ones that won't go are usually the 265tyres on the wider 8 inch rims, or the 235's on the 7 inch rims. In contrast, a 265 on a 7 inch rim or a 235 on a 6inch rim will always go up with a reasonable pump. And the difficult ones need a good whoosh from an air reservoir - thats why we have a few other tyres on the car - I doctored up a device from an ARB Deflater that allows you to inflate a tyre to max pressure, then take the valve out to give a big whoosh to seat the bead on the flat tyre.

Or unless you have badly damaged rims lube the rim/tyre "joint" and use almost any compressor. Hell I have done it on a Jackaroo's tyre with an cheapish ($60) compressor. If your having that much trouble seating the bead then try running a rope (ideally a ratchet style tie down) aropund the middle of the tread with a couple of truckies hitch to force the tyre walls outwards and help the process.

Take your spare off, let it down and break the beads (remove then refit to rim if you really have to) then try it, you'll be surprised how easy it is as long as the rims aren't badly damaged and you "lube" the tyre (water will do at a pinch)

Resetting beads has become a bit of an "urban myth" used to promote "upgrading" to larger compressors and and the latest NASA approved bloody bead breaker. (Don't get me wrong a good bead breaker makes it a lot easier but it isn't impossible to do on the side of the road with basic tools.

Too bloody right whyallacookie. Have used the rope trick myself - just twisted with a big srewdriver to force the bead against the rim the little crappy compressor I had in those days managed to do the rest. Didn't know how to do the truckies hitch back in those days!

Whyallacookie,
I don't think theres any "urban myth" there. I teach people on trips and club training days to fix tyres, often after rolling tyres off rims, or punctures, or simply as a training exercise. A lot of people have trouble, but with a few tricks and a bit of practice, they do better.

Yep you can use any compressor, and if everything's in your favour, it works. Before getting my first electric pump, I repaired tubeless and reinflated them with a hand pump (I was a bit fitter back then!) But that was in the 1970's.

In my experience, the rope around the tread trick doesn't do a lot on the modern radials - the tread buckles in before beads get pushed out. Used to work a treat in years gone by with the old crossplies though.

And to simply break the beads and reinflate is the easiest possible scenario - the bead naturally goes back against the rim. Try reinflating a spare casing thats been stored on a roofrack (squashed down), or one that with a distorted bead from heavy-handed levering.

Are you sure it wasn't an Ozito CO2 cylinder?

Which compressor will seal a bead? Obviously the higher capacity models would be the best but what have other user found to work well.

Most compressors can be used to reseat a bead...you just attach a ratchet strap around the circumference in the middle of the tread and put some reasonable pressure on the strap.


This bows the beads out and with a little careful handling you can just get the bead to grip and start to seat. You then remove the strap and continue inflating.

All the best.

Dick,

There are a few that will re seat a tubeless tyre on to the rim.

I have used the Big Red air compressure because it will and I have used it to reset a tubeless tyre.

Ed I've had a Typhoon for 12mths now and an excellent compressor. Very fast and excellent compression rating. Only drawback I've found is the hose connection to the tyre valve a bit cheep and nasty (on mine any way) so I swapped it with my older compressor's hose.

What's on your tyre valve Derek?

Andrew

It is the deflator. Our own PSV or 'Pressure Safety Valve'
