Self inflating tyres sound like one of the most phenomenal inventions, but they’re not exactly priced ridiculously high. In 2012 Goodyear developed these tyres, and they essentially pump air in when the pressure drops.
The mechanics are actually quite simple, which is why it’s surprising that they took so long to come around. An internal regulator opens to allow air flow into the a pumping tube, then as the well moves the part of the tyre touching the surface helps squeeze the air in the tube to an inlet valve in the tyre.
There’s no doubt that there are many people in society who can benefit form these tyres, especially those who have a long commute. Inventions are brought about each and every day, and not every invention become successful, so it will be interesting to see if the popularity for these tyres grows down the line.
