Topic: Will a foot pump seat the bead on my freshly installed tire (tyre)?

[spill]

I can't envision this working, but I figured I'd ask the experts before I roll my wheel down the street to the dollar-per-use air compressor at the corner gas station.

CB750F2, Comstars, 4.00 x 18 Metzeler Lasertec tire, 3.50-4.00 x 18 tube, 100psi foot pump.

It was surprisingly easy to install my first motorcycle tire this morning, but it was a struggle to get the old hard tires off last night.  I probably learned a bit of geometry in my sleep to help with the install though.

I read this on the Dunlop motorcycle web site:
'Follow these mounting precautions:
Wear approved eye protection.
Clean and lubricate beads and rim.
Centralize rim band and tube to prevent pinching if tube-type rim.
*Note directional arrows on sidewall where applicable.
Lock assembly on mounting machine or place in safety cage before inflating to seat beads.
Set air hose relief valve at 40 psi.
Use extension gauge and hose with clip-on air chuck. Stand back with no part of your body within the perimeter of the assembled tire and rim.
Inflate with core in valve stem.
Never inflate above 40 psi to seat beads.*
Spin wheel to check bead seating and alignment.
*If the beads do not seat by 40 psi, deflate and repeat above procedures. Never use a volatile substance or rubber "donut" to aid bead seating. If the tire is a tube-type, deflate and reinflate after seating to prevent tube wrinkles.'

I want to hear this thing seat the first time to scare the isht out of me. I'll post some more pics once they finished uploading.

 I hope it has a tube, if not.. no way..

 If you cleaned the bead, and soaped or tire-lubed it, it may go on. If it does not, it may go by riding it a bit with 20 psi in it.
 If you have a big mallet with some weight, and hit outside of tire while inflating, it may help. Also reposition, bead so it pops on last in different area if not going on (dont rotate tire)

Tire has a tube in it. I'm a little confused by 'Also reposition, bead so it pops on last in different are if not going on (dont rotate tire)'. 

So, don't rotate the tire; that makes sense. When/where should I reposition the bead? Oh wait, that's supposed to be area, not are. Got it.  Thanks for the tip. Anyway, I'm probably just going to carry my wheel down to the not-so-fast-buddy-this-air-ain't-free compressor at the gas station. Maybe I'll try the bike pump first though and report out.

Some more pics.

Foot pump didn't work (shocker). Took it to the my-nozzle-is-all-jacked-but-feed-me-four-quarters-anyway air compressor and it still didn't seat.  The tire looks pretty good on the wheel, but I didn't hear a popping sound. You're always supposed to hear a popping sound when the bead seats, right?  Even if I get this tire on, I'm taking it to a motorcycle mechanic to balance.

You get the popping sound when mounting tubeless tires on tubeless rims, as the bead seals to the rim to hold air, it is quite tight.

Tube type rims do not have the sealing/locking feature machined to the rim.  So, they don't automatically position themselves correctly.
The installer has to wrestle tubeless them into the seated position so the raised line near the bead is equidistant to the rim all the way around rim on both sides of the tire.  You cannot rely on the bead seal when matching tubeless tires onto tube type rims.  That's why you must use a tube with a tube type rim regardless of whether you have a tube type or tubeless tire mounted on it.

Yes, some take the risk and mount tubeless tires on the Comstar rims without a tube.  But, these people are ignorant about the how it was designed to function, or they are just going to sell the bike to some unsuspecting mark.

...The installer has to wrestle tubeless them into the seated position so the raised line near the bead is equidistant to the rim all the way around rim on both sides of the tire...

That's what I needed to read. I noticed that a 20cm section (on the circumference) of the tire was a few millimeters too far in.  'Wrestle' consisted of a rubber mallet, 27.5psi in the tube, and a wee bit of silicone spray (probably not the best idea, but the pressure from what came next most likely forced all of it out because the edge where the tire meets the rim was dry after the...). Thump, THump, THUmp, THUMp, THUMP(!) with the mallet, as 754 describes above, and the bead seats.  Symmetry achieved.

So, the foot pump worked afterall.

 Keep in mind if a mag does not have the bead lip, some machine a slight groove in them to do that.


 I have seen new stamped 2 pce wheels that had that..
