(upbeat music) – So on the sidewall of your tire, which is this portion,
every tire has a PSI, which is pounds per square inch. I always say pump to your max, because the lower your tires are, the harder it is to ride it. We grab our pump. If your pump does not have a gage, and you’re trying to figure out by hand, if you can squeeze your tire at all, it’s about half pressure. So it’s supposed to be pretty rock hard. So this valve is a Schrader valve, which most cars have. It’s our most standard form of valve. So we clip our pump head on, and we pump to our full PSI. Once we’re at full inflation, put your cap back on,
and you’re ready to go. The other form of valve is called Presta. They hold higher pressure air better, which is why we’re seeing
them on more and more bikes, and to allow in to pump your tires, you need to unscrew this little cap piece. When you’re done, make
sure to screw it shut.
