How to Inflate Bike Tires Without a Pump Turn the cap of the compressed air inflator counterclockwise by hand and remove the cap. Remove the valve cap from the valve stem on the bike tire.

Subsequently, question is, what kind of valve is on my bike tire? There are two basic types of valves that you’ll find on bikes: Presta and Schrader. For the most part, inner tubes and tubulars on road bikes will use Presta valves, and mountain bikes will use Schrader valves. In this way, why won’t my bike tires inflate? There’s a little pin that has to be pressed down in order for air to get into the tire, and if it isn’t pressed down enough, it won’t allow any air in no matter how much you pump. If that doesn’t help, your tire valve could be stuck closed, or the pump fitting (the thing you press over the tire valve) might be broken.How do you inflate a bike tire with a Presta valve?
