Checking tyre pressures takes two minutes, yet it is one of the most overlooked jobs on a motorcycle. The right pressure affects grip, braking, handling, comfort and how long your tyres last.
Grip and braking
A motorcycle tyre is designed to work at a specific pressure. Under-inflated tyres flex too much, overheat and feel vague. Over-inflated tyres shrink the contact patch, which reduces grip, especially on wet London roads.
Handling
Low pressure makes steering heavy and slow to turn in, and the bike can feel unstable in corners. Riders are often surprised how much sharper the bike feels once pressures are corrected.
Tyre life and fuel economy
Wrong pressures cause uneven wear: under-inflation wears the edges, over-inflation wears the centre. Both shorten tyre life. Low pressure also increases rolling resistance, so you use more fuel.
How to check
Check pressures when the tyres are cold, before you ride. Use a reliable gauge rather than a garage forecourt gauge, which can be inaccurate. Use the figures in your owner's manual or on the sticker on the swingarm or chain guard, and adjust for a passenger or luggage if the manual says so.
How often
At least every couple of weeks, and before any long ride. Delivery riders and daily commuters should check weekly. If one tyre keeps losing pressure, it may have a slow puncture or a leaking valve.
