How to Deflate a Bike Tire?

Now that you know in what situations you need to deflate your bike tires, the next question is how do you deflate a bike tire? But before I get to that, let’s talk a bit about the different valves in a tire.

Yes, bike tires can have different types of valves, and each valve has its own technique for letting air out. Check your tire to see what kind of valve you’ve. The most common types of valves are the Schrader valve, the Presta valve, and the Woods valve.

Each of the above valves releases air differently. So you need to know which valve your bike has. Once you figure that out, the rest is easy. Here’s how to deflate these valves.

Schrader Valve

Schrader valves, also known as American valves, are found mostly in cars and motorcycles. In bicycles, they’re primarily found in mountain bikes. Their main feature is that they’re shorter and thicker compared to other types of valves, with rubber caps for safety.

To release air from a Schrader valve, you must first remove the cap that seals it. The stem of the Schrader valve is threaded like a screw, so you simply twist off the cap and push it in with a pointed end. Screwdrivers, toothpicks, needle nose pliers, valve removers – they all work well.

Because the cap is designed to prevent dust and dirt from entering the valve, it’s securely sealed, and the air will only come out very slowly if you don’t push on the valve. If you want to release only a tiny amount of air, press the valve until the desired amount is left. If you’re going to release all the air, press until the hissing sound stops.

Presta Valve

Presta valves or French/Sclaverand valves are commonly used in road bikes. They’re long and narrow, unlike Schrader valves, and are secured by caps.

Bleeding a tire with a Presta valve is also reasonably straightforward. You must first remove the outer cap that secures the valve to do this. Then you unscrew the brass cap and press on the center of the valve with a metal object. If you don’t have a tool to help you with this, you can also use your fingernails and push out the desired amount of air. Then screw everything back on, and you’re ready to go!

Woods Valve

Woods valves, also known as English or Dunlop valves, are a mix of Schrader and Presta valves. They’re the same size as Schrader valves, but their mechanism is more like Presta valves. They have an outer valve stem with two caps, one on the inside and the other outside.

A Woods valve works much like a Presta valve. You’ve to remove the top cap to let the air out of the tire. Before you do that, you’ve to remember that the tire will deflate very quickly when you take the cap off. So keep an eye on it if you only want to deflate a little.

Tools to Help You Deflate a Bike Tire

Deflating a bicycle tire is pretty simple in itself, but some tools will make your life even easier. It’s best to get metal objects with a pointed end, such as screwdrivers, pin caps, valve removers, and needle-nose pliers.

But if you don’t have these on hand, don’t worry. You can also use your fingernails or a toothpick.

How Long Does It Take for Bike Tires to Deflate?

How long your bike tire takes to deflate depends on the amount of air and the type of valve. Road bikes usually ride best at 90-120 PSI, while mountain bikes need a value of 35-60 PSI. So it shouldn’t take too long to completely deflate.

And if you have a Schrader or Presta valve and push the valve down properly, the air should come out quickly. And if you have a Woods valve, the air will be out in no time!

How to Store Your Deflated Bike Tire?

The best way to store your tire after deflating it’s to fold it. Keep folding it back and forth on itself until the size of the tire is compact. Make sure the tire’s valve is on top and facing up, so it doesn’t touch the rest of the tube.

To store it, secure it with a soft string; don’t use a rubber band as it may stick over time. Wrap it in a piece of cloth or a sock and store it with your other bike gear.
