If Coda's claims are true, their Self Inflating Tires in development now seem like an inevitable future for car owners. The simple mechanism works with classic principles of a peristaltic pump: a tube is placed in each tire's sidewall. As it's run over, the tube's compression forces air in (filling the tire). A cut-off makes sure the tire doesn't explode. That's it. Sound too good to be true? Maybe. But having all tires on the road at optimal inflation could lead to a huge gas/energy savings every year (and as our friends at Jalopnik point out, it's pretty good for safety as well). So our ears are perked waiting for more information. (Note: the choice for no hyphen was that of the manufacturer, not our editors.) [product via jalopnik]
