Get the perfect balance

Getting tyre pressure right is vital at the top level and greatly increases enjoyment for all cyclists. On rough surfaces, a tyre at lower pressure can absorb more of the bumps than a tyre at higher pressure, with less deflection of the bike and its rider. Rolling on a perfectly smooth surface, a tyre at high pressure has less rolling resistance and therefore rolls faster than the same tyre would when run at lower pressure, for a given power input.

However, on rough, irregular surface tyres at lower pressure roll faster because they can deform to the surface, absorbing bumps without transferring forces to the rider or sapping the momentum of the bike and rider. At lower pressure, the contact patch between the tyre and the ground is larger. This increases grip and improves cornering traction.

Performance under pressure

What is the perfect tyre pressure? It’s all about finding that balance between grip and stability. Too high: Higher tyre pressures help support the sidewall of the tyre offering increased stability and increased protection for the rim, but go too far and the ride will feel harsh.Too low: Low pressures increase grip from the larger contact patch, however, run the tyres too low and you drastically increase the risk of rim damage from square edged hits and can create an unstable ride at speed.
