Would that not just give you two half-flat tyres? |
|
| |
Yes, I suppose because the pressures would balance out. I guess the valves would have to be one-way, you know the kind with the ball inside that blocks the passage. This would only work once connected to bikes with higher air-pressure. For example connecting a 60psi mountainbike tire with a 120psi racing bike tire. |
|
| |
But the mountain bike tyre will be perhaps three or
four times the volume of the racing tyre. This could
work if you had one flat tyre amongst many, taking a
little air from each, but not so well as a one-to-one. |
|
| |
Folding bikes typically have small tires, like those on kids bikes. This would probably be a practical device for those. |
|
| |
I still think bikes should be air operated, so ideally bike tires would be inflated by the bike itself. |
|
| |
In the urban environment, you could steal it from
truck/van tyres, nice high pressure and lots of
volume relative to the bike tire. However, you can
get some pretty small pumps. <link> |

Abstracting air from high-pressure truck and
bus tyres would work well, given the
disproportionate volumes. A pressure
regulator would be highly advisable. |
|
| |
Buses have the advantage that they make
predictable stops. |
|
| |
Aircraft tyres would be even better, being
filled with dry Nitrogen. They also make
predictable stops. |
