Here's a design concept that's long overdue: a digital valve cap that gives you an instant readout of your tire pressure with a simple push. Created by designer John Wrightson specifically for mountain bikers, the caps will let riders measure inflation in a hurry, without the inconvenience of a tire pressure gauge cluttering up their pockets.

If a device like this is rugged enough for mountain bikes, surely it can be used on car tires as well. Some high-end luxury cars can give you a tire pressure readout on their instrument panels, and there are aftermarket kits available, too, but this looks like it could be quick solution for the rest of us—a low-cost, easy way to quickly check your car's tire pressure. It's a great idea, because properly inflated tires last longer and give you better gas mileage. — Charlie White
