How to inflate a wheel without a pump? The old driver's secret
What to do if your tire flatted overnight and for some reason did not have a pump or compressor in your car. It's raining and I don't want to change it to a spare tire. You can stop a passing car and ask for a compressor (so that you can then get to the tire changer). As a rule, a tubeless tube lowers slowly during a puncture and if the damage is not large, then there will be enough time to get to the tire fitting.
But there are some tricky ways to inflate a wheel without a pump. The first way is to pump air from the other wheel to the deflated one. To do this, you need a silicone hose and two special fittings.
You can purchase a silicone hose at a hardware store. And the fitting is on aliexpress. Link here
We connect the fitting with a tube and fix it with wire or plastic ties.
We screw one fitting onto a tire with normal pressure, after bending the hose and screwing it onto a flat tire - the bend will be released and the pressure in the tires will begin to equalize. If the pressure in the inflated wheel was 2.2-2.4 bar, then it, of course, will drop and will be 1.5 bar. The same will be approximately the same in the deflated one. But this is enough to get to the tire service, located 1-2 km from you. Longer distances should not be traveled with this tire pressure.
Of course, this adaptation must be made in advance. It does not take up much space in the trunk and can help out. After all, the compressor powered by the cigarette lighter can also fail. I always drive a mechanical pump for the reserve.
There is another way how to pump a flat tire in 10 seconds without a pump. With carbon dioxide fire extinguisher and adapter.
You can also pump an empty cylinder of carbon dioxide fire extinguisher from the compressor to 4-6 bar and carry it with you. And, if necessary, pump up not only the wheels, but also the boat, the children's pool, inflatable mattresses for sleeping and swimming. You just need to press the handle of the fire extinguisher as smoothly as possible, otherwise it gives out too much air flow.
The third way is to inflate a flat tire from the exhaust gases of a car. For this, in addition to the adapter for the wheel fitting, an adapter for the exhaust pipe is needed. Who tried this method - write in the comments.
We will not consider dangerous methods of inflation of tires using the explosion of vapors of combustible substances. They are overwhelmed by YouTube.
