You’re kitted up, the sun’s out and the road is calling.
But wait, haven’t you forgotten something? A lot of riders skip it — and most can’t tell just by looking. Yes, we’re talking about checking whether your motorcycle’s tyre pressure is correctly inflated.
Don’t fret, though. In this guide, we’ll walk you through why tyre pressure matters more on a motorcycle than a car, how to find the right PSI for your bike and exactly how to check and adjust it yourself in just a few minutes.
Why Motorcycle Tyre Pressure Is So Important
While a car has its weight distributed between its four tyres, a motorcycle only has two.
That means every PSI matters. Motorcycles are uniquely sensitive to pressure changes because so much of your safety, from your braking to cornering, comes down to two relatively small contact patches between rubber and tarmac.
Get the pressure wrong in either direction and the consequences compound quickly:
Under-inflated tyres:
- Sluggish, vague steering: the tyre deforms too much under load, making the bike feel heavy and unresponsive
- Excessive heat build-up: the sidewall flexes more than it should, generating heat that can lead to tyre failure at speed
- Accelerated, uneven wear: the edges of the tread take the brunt, wearing faster than the centre
- Longer braking distances: reduced contact patch efficiency means the tyre can’t do its job under hard braking
Over-inflated tyres:
- A harsh, nervous ride: the tyre is too rigid to absorb road imperfections, transmitting every bump directly to the chassis
- Reduced grip: a rock-hard tyre has a smaller effective contact patch, meaning less rubber touches the road
- Centre-heavy wear: the crown of the tread takes all the punishment, dramatically shortening tyre life
