New tire mount?

Use a bike pump.  It will just take longer.

i highly doubt youll be able to get the bead to seat with the little pressure created by a bike pump. as for just refilling the tires, def the way to go.

You might have a hard time getting the bead to seat on a tubless tire with a bike pump.  Probably possible, but it might be easier to use a CO2 cartridge or two to get the first few lbs of air in it.  You could also get an air tank and pressurize it with the bike pump then use it to seat the bead.  The issue isn't achieving enough pressure, but being able to deliver enough volume of air to make the bead seat against the rim enough to seal.  Once the bead is sealing no problem airing it up the rest of the way. You can put a tie-down around the tire's center to squish it and make the tire expand out a bit to help get started.  Truck guys put a bit of accelerant in the tire then light it to make it seat 

I've done a bunch of street tires with just standard little motion pro tire levers in my garage and a bit of old garden hose split lenghtwise for rim protection.  Very doable, but a bit annoying.  For the most part now I find it worth the $25 to have the shop mount and spin-balance the tires for me - especially since the wife is working at the shop, I just toss the wheels in her cage and they come back with fresh meats installed

I admire and whole-heartedly approve your tecnique!

not to be a stickler, but the second half of your sentence defines pressure. P=Normal Force/Area. P= deliver enough volume(normal force)/the bead seat against the rim(area).

i think he was referring to the onset of pressure versus constant pressure.

there has to be enough pressure to push the sides out to get a seal

anyhow, i was just joking with my bike pump comment.  you'd have to be quite daft to try that.

[bikepilot]

By pressure I mean that a bike pump will make plenty of pressure (my road bike tires go to 140 psi), but can't deliver enough volume of air to get sufficient pressure when there's a huge leak (like a bead not seated).  So in a round-about way its a pressure issue, but the reason its a pressure issue is that the bike pump can't deliver enough cubic feet of air quickly enough.

Been a while since I ciphered in phyziks, but I think the parameter needed is called volumetric flux: http://en.wikipedia.org/wiki/Volumetric_flux.

As soon as the forks fall off your bike, we still have a running bet... 


Back on track: I'd like to know how did the tire mounting go and what was the final cost. Because if it's really about $120 I have some beers for bikepilot and a pair of rims too

I'll bring the beer if I can watch and learn. I really don't want to pay to have tires put on the Daytona after my $30 for both on the Monster deal from Mike.

well....that deal is long gone since Mike has moved on to other endeavours...
