How to Pump Bike Tyre: Easy Guide For Beginners

Inflating bike tyres is a basic skill essential for any rider. However, with different pressure levels, valve types, and pumps, the process may feel a bit daunting for someone who is new to cycling. If you are also confused, don’t worry. In this guide, we’ll show you how to pump a bike tyre properly and explain the basics of common valve types, PSI, and pump options.

Find the Right Pump

Whenever you are wondering "how do I pump a bike tyre?", you should first understand which devices will come in handy for you. There are many types of bicycle pumps, each with its advantages and features. Let’s puzzle out their differences so that you can find the right pump for your needs.

• Hand pumps: small and lightweight pumps that are easy to carry in your backpack or on the bike frame. They typically have a flexible hose and a lever or piston to compress air into your tyre. Hand pumps are perfect for emergency inflation while on a ride, although they require more time and effort to fill the wheels with air. However, you may also use an electric pump, which makes the process much easier.

• Floor pumps: high-volume pumps with a wide, stable base that allow you to inflate tyres more quickly, conveniently, and effortlessly. They are ideal for regular bicycle maintenance at home, but will not suit for on-the-go inflation. Many floor pumps also come with a pressure gauge, making it easy to inflate your tyres to the correct PSI.

• CO2 pumps: lightweight and portable pumps, ideal for carrying in a pocket or a riding bag. To use it, you need to attach a small CO2 cartridge to the inflator, screw the inflator onto the tyre valve, and then release the gas. Since the process is super quick, such pumps are typically used for emergencies (e.g., before a race). However, the cartridges are non-refillable, so you need to purchase another one after every use.

Prepare Your Bike

The process of preparing your bike for tyre inflation is pretty simple. First, unscrew a small plastic or metal dust cap to expose the valve stem. If there’s no one, don’t worry – it’s needed just for cosmetic purposes. Once done, make sure that the valve is clean and ready to attach the pump. If you notice any dirt, mud, or debris, wipe it with a damp cloth.

Check the Valve Type

Before learning how to pump a bicycle tyre, it’s important to determine which type of valve you are going to deal with. Hence, you will know which pump head to use for efficient type inflation. Presta and Schrader valves are the most common today:

• Presta valves: can be found on the majority of modern bikes. They are much thinner than Schrader valves, have a syringe-like shape, and come with a lock ring at the top that holds the air closed.

• Schrader valves: are common on older or cheaper bicycle models. Schrader valves are wide and cylindrical in shape, resembling car tyre valves. They also have a spring-loaded inner pin to let the airflow in and out.

How to Pump a Bike Tyre with a Hand Pump

Hand pumps are easy to use, so you will hardly encounter any problems during the process. Check out step-by-step instructions on how to pump up a bike tyre with a hand pump:

1. Attach the pump. First, make sure that the pump’s nozzle hole fits the type of your tyre valve (Pesta requires a narrower opening). If you have a Schrader valve, just screw the pump head onto the valve stem to secure it. If your bike tyre comes with a Presta valve, unscrew its lock ring before starting the inflation process and then firmly connect the pump head to the valve. You may also hear some air escaping from the tyre when attaching the pump – this is completely normal. Please note that some pumps have a locking mechanism, requiring you to flick a lever when attached to the valve.

2. Pump the tyre to the desired pressure. Hold the nozzle on the valve with one hand and start pumping with the other. Meanwhile, use full strokes for the maximum air flow. If the type refuses to inflate, check it for punctures.

3. Remove the pump and close the valve. Carefully remove the head of the pump so as not to damage the valve. If there’s a locking mechanism, flick the lever back before releasing the valve. Finally, screw the dust cap to keep the finest components clean. If you have the Presta valve, don’t forget to close its lock ring before placing the cap.

How to Pump Up a Tubeless Bike Tyre

Tubeless tyres are similar to the standard when it comes to inflation. But you should still follow some guidelines so that the sealant does not become stuck inside the pump head, preventing proper air passage. So, here’s how to pump up a bike tyre without an inner tube:

1. Make sure that the tyre bead is properly seated on the rim. Add sealant if needed.

2. Rotate the wheel so that the valve stem is 90° vertical to the ground level. This allows you to keep the sealant at the bottom of the wheel, away from the valve.

3. Most tubeless setups have Presta valves – unscrew the lock ring and press the valve core for a few seconds so that any remaining sealant can exit the stem completely.

4. Attach the pump head to the valve and inflate the tyre.

5. As soon as the tyre is inflated to the right pressure, remove the pump and screw the dust cap.

Why Proper Inflation Is Important

Tyre pressure is measured in PSI (pounds per square inch) and shows the amount of air inside the wheels. By knowing how to pump bicycle tyres to the right pressure, you will not only enhance your cycling experience but also make rides safer. Consider the risks of under- and over-inflation:

• Handling: too high tyre pressure makes a 2 wheeled bike feel bouncy on uneven terrains, which affects the overall comfort and control negatively. Low pressure, in turn, causes sluggish handling on rough trails, steep inclines, and sharp turns since the tyres tend to deform more.

• Safety: over-inflated tyres are easier to damage, especially on rocky terrain, while under-inflated tyres are more prone to blowouts and flats.

• Comfort: if tyres are inflated to the right PSI, they absorb shocks from bumps and road vibrations, making your trips more enjoyable. Pedaling feels easier as well.

How Do I Know When I’ve Pumped Enough?

"How do I pump up a bike tyre to the right pressure?" is probably the most popular question among beginner cyclists. Well, it depends on your tyre type. For example, bicycles with wider wheels, like MTBs, require 5-20 PSI, whereas road bikes with narrower tyres typically have between 80 and 130 PSI.

Basically, every manufacturer specifies the recommended PSI on the tyre’s sidewall, and you can achieve it easily if your pump comes with a pressure gauge. In case you don’t have it, just press on the sidewall with your thumb. On the road bicycle, you shouldn’t be able to push the tyre in at all, while on the MTB, it should get inward by about a centimeter.

Maintaining Your Bike Tyres

Proper bike tyre maintenance is one of the easiest ways to make your rides safer, smoother, and more enjoyable. Plus, this helps save your time and money for complex repairs. Keep in mind the following tips:

• Check tyre pressure before every trip, especially if you have a cargo bike

• Learn how to use bicycle tyre pump correctly 

• Clean the tyres after muddy rides to prevent premature cracking

• Inspect the tyres regularly for signs of damage or wear and replace them in time

• Store your bicycle in a cool, dry place to slow rubber deterioration

Conclusion

Keeping bike wheels properly inflated is essential for your cycle to perform at its best. And after familiarizing yourself with our guidelines on how to pump the bike tyre, you know that the process isn’t complicated at all. Just remember to check the recommended PSI on the tyre sidewall and maintain your bicycle properly so that you can hit the road with confidence and maximum pleasure.
