Yes, this is the latest nerdy deep-dive with Jason Fenske, the man behind the delightfully detailed YouTube series Engineering Explained. While you probably already know why an under-inflated tire reduces your fuel economy, we’re betting there’s something in here that you haven’t fully grasped before—whether it’s the physics equation that connects ambient temperature to air pressure, or the fact that there’s a nifty wireless tire-pressure monitoring system you can add to any car that just plugs into your dashboard 12v outlet.
Even if you understand the mechanics of tire inflation and the importance of keeping your tires inflated properly, a refresher course never hurt anybody. Engineering Explained to the rescue.
So, go ahead, learn something today. Not that we’re trying to put you under any undue . . . pressure.
