Having great trouble getting a Maxxis Advantage to inflate on Mavic XM719 rim using a new Stans tubeless rim strip.
This rim strip is different to the old one which it replaces; it has a recessed ridge in the centre that the tyre when deflated just drops back down into. (I can only get it inflated with a CO2 cartridge without the valve core in).
I have tried to fit another rim tape underneath to get a better seal, but this doesn’t seem to have worked either.
Does anyone have any ideas?
Thanks!
Is it a used Advantage? The first time I set mine up tubeless they were fine but then changed them for something else. When I came to refit them it was as though the bead had stretched and they were really loose. Had to use C02 to inflate them.
Try the pikey inflator. I had problems with a mavic rim and a scwhalbe tyre. Worked with the pikey inflator
Pikey inflators rock!
Cheers for the replies!
The advantage is "used", although this is the first time I have had to take it off the rim and only then because the valve came off the old Stans rim strip.
Have done things in a different order, ie, put in sealant, inflate with CO2 put figure over valve then screw in core. Seems to have worked, we shall see!
Have tried the pikey inflator, i think i need some tubing with a larger internal diameter (I’m just using tube off the track pump?) because even with 100psi it won’t inflate a tyre like the CO2 does.
Hopefully I won’t be walking home today...
100psi in a cola bottle 😯
I've never needed more than about 40. You taken the core out of the valve you attach the tube to at the bottle end?

Sticky insulation tape - couple of layers, gives a tighter fit.
pikey inflator?

Get on it asap - I was really astounded by it.
i use a less pikey, but equally handy inflator - another wheel.
1. find an inner tube with a removable valve core (or just break the core out of a tube) and put it on a spare wheel with a spare tyre;
2. pump up the spare tyre with a track pump;
3. use molegrips to pinch the track pump tube;
4. unscrew the track pump hose from the pump end (mine is a joe blow, and this is easy);
5. plug the now bare end of hose onto the valve (with core removed) of the tyre you're trying to inflate;
6. remove the molegrips;
7. admire your inflated tyre!

Thats ^ exactly what I have been doing, just dosnt deliver the air quick enough no matter what the pressure!
Perhaps its because im using a blackburn pump...
if you are using an inner tube as your reservoir, have you definitely removed/destroyed the valve core, and made sure there is none of it left to obstruct the air flow?
for a stubborn tyre, the two things i do in addition to the above are:
- seat the tyre using an inner tube and leave it, then only unseat one bead when I swap back to using a stans valve (not sure if this is applicable to you since you're using rim strips - i've got yellow tape and a separate valve).
- almost neat fairy liquid brushed around the bead *immediately* before releasing the air from the compressor reservoir.

Ah missed the bit about you using a inner tube in a tyre, im just using the valve from an old tube, without the core, attached to a coke bottle.
The almost neat fairy liquid sounds like a plan next time, iv always used fairly watered down stuff...
