Looking after your motorcycle tyres isn’t just about checking the tread level once in a while. You should also check that they’re properly inflated, ideally once a week, to keep the bike safe and handling well. Just like cleaning your motorcycle, checking tyre pressure doesn’t take long. It’s a quick job that can make a big difference every time you ride.

Read on to see how to check the pressure of your motorcycle’s tyres, or head to our guide to motorcycle tyres for more tips on keeping them in top condition.

Why Correct Motorcycle Tyre Pressure Matters

There are many good reasons to ensure your motorcycle tyres are at the correct level of pressure.

Safety and handling

Under-inflated motorcycle tyres spread out on the road under the weight of the bike and rider. This reduces grip, something you’ll notice most when braking or cornering, and it makes the bike less safe to ride, even if the tyres look fine. Acceleration and stability also suffer when the pressure is too low.

Over-inflated motorcycle tyres bring the opposite problem. They bow out at the sides, with less rubber in contact with the road. That means reduced traction. Over-inflated tyres are also more likely to blow out, which can have serious consequences, especially at high speeds.

Tyre longevity

Keeping your motorcycle tyres at the right pressure will help them last longer. Under-inflated tyres create extra rolling resistance, which builds up heat and speeds up wear. Over-inflated tyres wear faster in the centre of the tread, since only a small strip of rubber is in contact with the road. Regular checks mean your tyres will stay in good condition for longer and won’t need replacing as often.

Fuel economy

When your motorcycle tyres are under-inflated, they create extra rolling resistance. The engine then has to work harder to keep the bike moving, which uses more fuel than necessary. Over-inflated tyres are not much better, since they reduce efficiency by limiting how much of the tread is in contact with the road. Keeping tyre pressure within the recommended range is a simple way to save fuel and stretch out every tank.

Legal issues

Tyre pressure is not just about performance. It is also a legal requirement. Riding with seriously under-inflated motorcycle tyres can lead to an MOT failure if the bike is judged unsafe. In some cases, an insurer might reject a claim if it looks like the tyres have not been properly maintained. Staying on top of your tyre pressure takes only a few minutes but protects you from fines, failed tests and insurance problems.

How to Measure Motorcycle Tyre Pressure Step by Step

If you want to check the pressure in your motorcycle tyres accurately, follow these steps:

• Always measure tyre pressure when the motorcycle tyres are cold. Warm tyres can give a false reading, so let them cool down first.

• Your bike will have specific pressure values for the front and rear tyres. They are often different, so check the swingarm sticker or owner’s manual for the correct figures.

• Remove the valve cap from one tyre and keep it safe. These are easy to misplace but important because they protect the valve from damage while riding.

• Press your tyre gauge nozzle firmly onto the valve stem to make a tight seal. A little air might escape at first, which is normal. Just ensure the gauge is sealed before taking the reading.

• Check the reading on the tyre gauge and compare it with the manufacturer’s recommendation. If the pressure is too high, use the gauge’s bleed function to release air. If it is too low, pump the motorcycle tyre up until it reaches the correct level.

• If you need to inflate your motorcycle tyres, which is more common, use a pump or compressor and re-check the pressure with your gauge.

• Once the pressure is correct, replace the valve cap and repeat the process on the other tyre.

Common Mistakes When Checking Motorcycle Tyre Pressure

Some riders skip regular checks because their tyres don’t look flat. That’s risky if you’re heading out on a long ride or carrying a passenger and luggage. Extra weight and miles make your tyres lose pressure faster than usual. If you are planning a longer ride, see our comprehensive guide to motorcycle road trips.

Another mistake is ignoring how temperature affects motorcycle tyres. A sudden cold snap can lower pressure noticeably, while hot weather can raise it. If the weather has shifted recently, assume your pressures have changed too. Many riders also make the error of checking tyre pressure during a ride at a petrol station. Warm tyres give inaccurate readings. It’s better to check at home before setting out, or wait until the bike has cooled before using a gauge.

Finally, don’t assume the problem lies with just one tyre. If handling feels off, check both motorcycle tyres. One may look fine but still be under-inflated, so always measure each one.

Best Motorcycle Tyre Pressure Gauges

When looking for a top-quality tyre pressure gauge, accuracy is key. Ideally, purchase one that can measure the pressure to within one PSI so you can calibrate your tyres precisely.

• Other useful features to look for include a backlit display, which makes tyre checks easier at night.

• Compact gauges are a good choice for tourers, since they take up little space in your motorcycle luggage.

• Additionally, a flexible hose can come in handy, as it makes it easier to reach the valve stems without having to kneel on the ground.
