Understanding the correct tyre pressure for your bicycle is just as vital as inflating the tyre itself. The tyre pressure, measured in pounds per square inch (PSI), varies depending on the type of bike, the rider’s weight, and the riding conditions.

This information is usually found on the sidewall of your bike tyre and should be adhered to every time you inflate your tyres (1)

Key Takeaways

  • Identify the valve type and use the suitable bike pump.
  • Inflate to the correct pressure as stated on the tyre’s sidewall.
  • Regular tyre pressure maintenance ensures better cycling performance.

Properly inflating your bicycle tyres is essential for optimal performance and safety. Follow this straightforward guide to ensure your bike tyre is pumped to the correct pressure.

Find the Right Pump

Ensure you have the correct pump for your bike’s valve type. There are two common valve types: Presta, typically found on road bikes, and Schrader, similar to those on car tyres. Some pumps fit both types, while others need an adaptor.

Prepare the Valve

Remove the dust cap from the valve. If you have a Presta valve, unscrew the small nut at the top of the stem. For Schrader valves, ensure the valve is clear of debris.

Attach the Pump to the Valve

Secure the pump head onto the valve. The head levers must be flipped up for floor pumps to create a seal. For mini pumps, screw the head onto the valve thread.

Pump the Tyre

Inflate the tyre, checking pressure with the pump’s pressure gauge. Each tyre has a recommended PSI range, often marked on the tyre’s sidewall. Stop pumping once you reach the ideal pressure.

Disengage

Carefully remove the pump from the valve. You might hear a little air escape – that’s normal. It’s just the air that was between the pump and the valve.

Close the Valve

For Presta valves, screw the nut back down and then replace the dust cap. For Schrader valves, put the dust cap back on. This keeps the valve free of dirt and ready for your next ride.

What Valve Does My Bicycle Have?

Determining the type of valve your bike tyre has is essential to pump your bicycle tyres correctly. Each type of valve may require a different pump or pump head type.

Presta Valve

The Presta valve, often found on road bikes, is narrow and known as the French valve. Before attaching a pump, you must unscrew the small nut at the top of the valve stem. A pressure gauge will assist in inflating the correct PPI.

Schrader Valve

Schrader valves are wider than Presta valves and similar to those found on car tyres. They can be easily pumped at petrol stations, but ensure you press the pump head firmly onto the valve to prevent air from escaping.

Dunlop/Woods Valve

Less common, the Woods or Dunlop valve is a hybrid of the Presta and Schrader and can often be pumped with either type of pump. Verify that your pump is compatible to avoid damage to the valve.

Tubeless Valve

Tubeless valves are used in tyres without an inner tube and resemble Presta valves. The key to pumping tubeless tyres is ensuring an airtight seal to maintain tyre pressure over time.

What Pressure (Psi) Should My Bike Tyres Be?

A bicycle pump is attached to a tire valve. The gauge reads 50 psi. The pump handle is being pushed down to inflate the tire

Selecting the appropriate tyre pressure for your bicycle impacts performance, comfort, and safety. You’ll typically find the recommended psi range printed on the tyre’s sidewall. Here’s a general guide:(2)

  • Road bikes: 80-130 psi
  • Mountain bikes: 25-35 psi
  • Hybrid bikes: 40-70 psi

The specific pressure within these ranges depends on numerous factors, including rider weight and riding conditions.

Presta versus Schrader Valves
The type of valve on your bike tyre, either Presta or Schrader, requires a compatible bike pump. Presta valves, slimmer and often found on road bikes, require unscrewing the small nut to allow air in, while the wider Schrader—similar to car tyres—has a spring mechanism.

Checking and Adjusting Pressure
To check your bike tyre’s pressure:

  1. Remove the dust cap from the valve.
  2. Attach a pressure gauge or a bike pump with a built-in gauge.
  3. Adjust as necessary, inflating with a pump if below the recommended psi.

Always recheck the tyre pressure after attaching the pump, as air can escape, causing a pressure drop. Tighten the valve caps after inflating.

Remember, tyres will naturally lose pressure over time, so check regularly to ensure your ride remains smooth and efficient. This helps avoid punctures and potentially dangerous tyre blowouts, ensuring you can cycle confidently and safely on every bike ride.

What Type of Pump Do I Need?

Selecting the correct bicycle pump is crucial for efficiently inflating your tyres. The compatibility with your valve type and the intended use are primary factors to consider.

Track Pump

A track pump, also known as a floor pump, is a good investment for home use due to its high volume and pressure capabilities. These pumps often come with a pressure gauge, allowing you to quickly inflate your tyres to the correct psi.

  • Valve Compatibility: Most track pumps fit Presta and Schrader valves, the standard bike valve types.
  • Efficiency: Ideal for achieving high tyre pressures with minimal effort.

Mini Pump

A mini pump is a portable solution designed for bike rides. Although it takes more effort to reach high pressures, its compact size is beneficial during a ride.

  • Compactness: Small enough to fit in a cycling jersey pocket or mounted onto the frame.
  • Emergency Use: Best suited for mid-ride puncture repairs rather than regular maintenance.

CO2 Inflator

CO2 inflators use compressed carbon dioxide and are valued for their rapid inflation speed, which makes them a favourite amongst road cyclists and racers for quick tyre inflation after a puncture.

  • Speed: The quickest way to get your tyre back to full pressure while riding.
  • Single-Use: Each cartridge provides a one-time inflation, so carrying spares is advisable.

How Often Should I Pump Up My tyres?

Proper tyre inflation is crucial for the safety and performance of your bicycle. Bike tyres naturally lose air over time, so regular checks are essential. How often you should pump your tyres depends on the type of bike you ride and how usually you ride it.

For road bikes, it’s recommended to check tyre pressure before every ride due to their high tyre pressure and thin walls. With their thicker tyres, mountain bikes and hybrids might need pumping every two weeks as they hold their pressure longer.

Presta and Schrader valves are the two common types of valves on bike tyres:

  • Presta valves (narrower and often found on road bikes) should be checked more frequently.
  • Schrader valves (wider, like those found on car tyres) keep air longer and require less frequent checks.

Here is a simple guide to how To Pump A Bike Tyrehelp you maintain optimal tyre pressure:

  • Road bikes: 80-130 psi
  • Mountain bikes: 30-50 psi
  • Hybrids: 50-70 psi

These are general guidelines; always refer to the psi recommendations on your tyre sidewall for the accurate pressure range. To inflate your tyre:

  1. Remove the dust cap from the valve.
  2. If you have a Presta valve, unscrew the nut at the top.
  3. Attach the pump to the valve – ensure the pump head is compatible with your valve type.
  4. Inflate the tyre, checking the pressure with a pressure gauge.
  5. Once inflated to the desired pressure, remove the pump carefully to avoid air loss.
  6. Screw the cap back onto the Presta valve or replace the dust cap on a Schrader valve.

Use a good-quality floor pump with a pressure gauge for best results. Remember, optimal tyre pressure ensures a smooth, efficient, puncture-resistant bike ride. Keep your tyres properly inflated and enjoy your cycling experience.(2)
