Tyres

Tyre size is determined by your wheel diameter and the width your frame and fork can accommodate. Most tyres are labelled with two numbers, such as 700x25c or 29x2.4, indicating diameter and width. Check your current tyre sidewall or your bike's manual for the correct sizing before purchasing a replacement.

Each tyre type is designed for a specific riding surface and style. Road tyres are narrow and smooth for low rolling resistance on sealed surfaces, while mountain bike tyres are wider with aggressive tread for grip on dirt and loose terrain. Gravel tyres sit in between, offering moderate tread for mixed surfaces, and hybrid tyres are a versatile option suited to commuting on a mix of paths and roads.

Narrower tyres roll faster and are better suited to hard, smooth surfaces where speed is the priority. Wider tyres provide more air volume, which improves comfort, grip, and stability on rough or loose terrain. The right width depends on your riding style, the surfaces you cover, and the clearance available in your frame and fork.

Slick or semi-slick tyres work best on sealed roads and smooth paths where rolling efficiency matters most. Tyres with open, knobby tread patterns are designed for dirt, gravel, and trail riding where grip and mud clearance are important. If you ride across a variety of surfaces, a mixed or file-tread pattern offers a practical balance between speed and traction.

Worn tyres are one of the most common causes of reduced grip and increased puncture risk. Signs that replacement is due include visible wear on the tread centre, cracking in the sidewall, frequent punctures, or a noticeably flat profile where the tyre has squared off. Replacing tyres before they fail completely is a straightforward way to maintain safety and ride quality.
