Tires are where your bike meets the road. They influence grip, comfort, rolling resistance, and puncture protection more than any other single component. Upgrading tires is often the best performance investment you can make.
Width and pressure
Wider tires at lower pressures are faster and more comfortable than narrow tires at high pressures for most real-world riding. Modern road bikes fit 28 to 32 mm tires, and gravel bikes accept 38 to 50 mm. Run the lowest pressure that avoids rim strikes.
Tire types
- Clincher: traditional tire with a separate inner tube. Easy to repair, widely available.
- Tubeless: sealed to the rim with liquid sealant. Self-seals small punctures, allows lower pressure.
- Tubular: glued to the rim. Lightest option, primarily for racing.
- For most riders, tubeless clinchers offer the best balance of performance and convenience.
Tread patterns
Slick or near-slick tires are fastest on paved surfaces. The thin grooves in road tires are for water displacement, not grip on dry roads. For gravel, a file tread center with knobby shoulders handles mixed conditions. Full knobs are for mud and loose surfaces.
