Had a quick go last night at trying to fit a Maxxis High Roller wire bead to a stans flow rim with a track pump and failed miserably, was wondering if I could do similar to the Hope brakes bleed kit where you use the pressure from a car tyre to force the fluid through the system, if I inflated a car tyre to approx 45psi then used an old foot pump hose with a connector at each end, would this supply enough air quickly enough to seat the bead on the rim? Has anyone else used this method to seat a tyre? Don't want to buy a compressor to do the job but now I have my new wheels and change tyres quite frequently due to local conditions, am hoping this may be an easy solution. Local garages all use the pre set pressure type of inflators that do not supply volume quickly enough.

Any other suggestions also welcome.

I use C02 canisters. Got loads cheaply online. Also means if you burp on the trail you can always pop the tire back on easily.

I also found using a teflon based spray (GT85etc) helped the tires seat easier than soapy water. No idea why though.

You tried pressing the flat tyre button the local garages compressors?

A friend used to use a fire extinguisher which he rigged to a track pump hose so he could pump it up, basically using it as a reservoir exactly the same way as a car tyre. It worked for him, I'd do it.

I thought about that but not tried it - seemed to me that most adaptors don't allow much flow of air. Compressor works fine - I considered it a decent investment.

FWIW I have fitted door insulation strip/tape to the well of the rim, makes the tyre tight to get on and does need replacing now and again, but makes inflation much easier.

I assume your using the Flow rim strip? If your struggling to get them to seal take the rim strip off and lay a run of velox cloth tape on the rim first, helps build up the height of the rim to take up any slack between the tyre and rim strip.

For what its worth, my Flows (with rim strip) and UST tyres go up with a hand pump, normal tyres requird a bit of a pull/stretch to get them to catch with a track pump.

and a smear of neat washing up liquid around the bead 😉

i had a nightmare trying to get a wire bead crossmark onto a normal rim with a stans strip. no matter what i tried it wouldnt go on (mechanics air line almost did it. When i used a tubeless tyre from my other bike it just inflated straight away. Have you tried inflating the tyre first with an inner tube in and leaving overnight?

The tyres have been run with tubes for a couple of weeks. The flow rim strip was already fitted (Hope hoops from Wheelpro)

Can't pump any faster and tyres have neat washing up liquid around the bead

Not seen a flat tyre button on the garage compressors

What compressor can you recommend?

Following something I read on here, I tried just a dab of contact glue around the problem area (near the valve), after failing miserably for about an hour with a track pump. Worked instantly and it peels off easy enough so shouldn't cause any damage to anything.

Roof rack strap around circumference of the tyre squishes it down and reduces the volume to get it started more better. Big difference twixt my new track pump and my old one aswell.

I found resting the wheel on a bucket so there was no pressure on the tyre, this prevented it opening up a gap and leaking air.

Or try the explosive method. Some lighter gas, butane/propane (?) spray inside tyre, light it (probably at arms length). Think there were threads on here with this method ( [url= http://www.singletrackworld.com/forum/read.php?f=2&i=3623163&t=3623163 ]must have been on Mk I forum[/url] ).

I had linked to it from [url= http://www.mtbrider.com/mtbr/showthread.php?t=16917&highlight=explosive ]here previously[/url]

If you're over my neck of the woods drop in and I'll get it seated with my compressor.

I know roger does the yellow tape on those wheels (ive got some :0) but the flow rim strips are the black rubber strip and not included with the wheels (unless you asked for this extra?) so is that deffinatley what you have?

Another guy with Flow/Maxxis is having a similar problem.

http://messageboard.notubes.com/viewtopic.php?f=1&t=2208

The Notubes guy does not mention the use of an additional rim strip just yellow tape although his respose is a little vague. Might be worth a post to get some more info out of them or see if the guy has solved the problem.

edit: In the above topic you remove the valve core to get better air flow to help seat the tyre. The valve corte simply unscrews.

That was my post on the notubes forum.

I ended up installing the black rubber rim strip, but still had to use a mate's compressor to get them to mount. Just couldn't get enough volume of air in any other way.

Folding Maxxis Advantage's on Flow's, been running faultlessly since.

What about that thing that the 4*4 and enduro explorers geezers do........

You know where they squirt some WD40 into the tyre then introduce a naked flame around the bead? Pops the tyre up to full pressure in a flash. 🙂

I'm sure I remember someone on here recommending it.

Rim strip is just the yellow one, valve core removed for better airflow.

Wheel was hung up as per the video instructions on the stans web site so no pressure anywhere on the tyre

Stu, thanks for the offer but don't know when I'll be over that way (certainly not this week as the car is in for repairs)

Will be having another crack tonight as I have more time

The advice I got from Jon at JRA was to use the Flow specific rubber strip if using conventional tyres for a conversion and to use just the yellow tape if using a UST tyre.

Like STATO said above, it's about getting a snug fit between the tyre and the rim. Sounds like it needs building out a bit and the Flow strip would do this. Having said that, quick hit with a Co2 cart would do the trick as well but only works if you've got the injector to add fluid through the valve once it's up (you did take the valve core out right?) as the solution doesn't like Co2 all that much.

Try resting the wheel on an open bucket. That's what I used to do although I haven't tried many tyres.

I was advised to hold wheel horizontal which sorted it for me

After all the advice above I ordered a pair of the rim strips, neat washing up liquid on the beads and hey ho, inflated them with a track pump.

Thanks for the help guys (and gals if applicable)
