    OK, admittedly not as ghetto, therefore not as cool as the pop-bottle version, but as I had one of these Ronseal creosote-sprayer hobbies in the garage, and a very stubborn Conti X-King that just refused to play, it got cracked out…

    Bit of 6mm internal diameter tubing and a pair of mole grips, job’s a good un…

    The beauty of the Ronseal (other varnishes are probably available) thing is that it has a built in pump and a pressure release valve set at 45psi. At 5L capacity that’s enough stocked energy to pop the beads on most tyres, I reckon.

    Less fun than pumping a Coke bottle up to 100psi, granted.

    Cool! And the valve and logo are aligned!

    Stick a presta valve on in place of the pressure valve and it will go higher than 40 psi. Then add a proper track pump tube and chuck and you have my set up.

    Have something very similar myself. Works very well and was cheap and simple to make.

    Min had a trigger on it for the spray so I added the tubing after that so no need for the mole grips. I roughly checked the safety on mine using a track pump and it was about 60psi. A 3L sprayer got a 2.2″ 29er seated comfortably. I’m sure someone could figure out the sizes and pressures that would work (Ideal gas/Boyles law) but got for about 5L and it is probably going to work unless it is a fat bike.

    ^oldnpastit^ ‘course the valve lines up with the tyre label! Whaddya take me for?

    ^jonba^ now why didn’t I think of that? Doh!

    Shirley if the tyre wont inflate with a basic floor pump then the fits too loose and needs more tape? Fooling the tyre into inflating with a high pressure pump will leave the tyre prone to burping?

    Cool set up though.

    Go high pressure

    120psi will seat & inflate 2 tyres easily. 🙂

    For me I use standard tyres. I find a short sharp blast of air is needed to seat some tyres – particularly if they’ve been on and off a couple of times. I’ve never had a problem with burping. Some tyres I managed with the track pump but this is 100% effective with no soapy liquid etc. so minimal faff which is great.

    ^enfht^ as the trye beads actually seat on the ‘shoulders’ of the rim and not in the well, not convinced that more rim tape would help a lot. Annyhoo, these are Mavic Crossmaxes with the snazzy Mavic UST sealed box-section rims, so no tape involved.

    I think the issue is how well the rim/tyre combo match up – for example I have never had the least problem with any tyre from Hutchinson or from Maxxis with these rims – they all seal with the least puff from a track pump, regardless of whether they are tubeless ready or not. Schwalbe – massive PITA, really hard to get ’em to pop. These Contis were a real struggle too until I broke out the Ghetto inflator 🙂

    Remains to see if they are more burp-prone in action….will report back.
