Gravel Bike Tire Guide
Choosing tires for speed, comfort, and grip on mixed terrain.
Gravel bike tires need to be versatile for mixed surfaces. This guide covers popular 700c (32c-50c) and 650b (e.g., 47c) gravel tire widths, discussing how width impacts comfort and float. It explains different tread patterns (slick centers, side knobs), the advantages of tubeless for gravel, and appropriate tire pressure ranges for optimal grip and comfort on varied terrain. Key for anyone riding beyond smooth pavement.
Gravel tires for 700c wheels typically range from 32c to 50c, with 38c-45c being very popular. Wider tires offer more comfort and float on loose surfaces. 650b wheels are also common, allowing even wider tires (e.g., 650bx47c) for similar overall diameter to a narrower 700c tire, enhancing cushioning and grip.
Tread varies from slick centerlines for speed on pavement to small, tightly packed knobs for all-round grip, or more aggressive knobs for loose/muddy conditions. Compounds balance rolling speed with durability and puncture resistance.
Most gravel riders prefer tubeless setups. Tubeless allows lower pressures for better traction and comfort, and sealant helps prevent flats from thorns and small cuts common on unpaved routes.
Gravel tire pressures are typically lower than road bikes (e.g., 30-60 PSI / 2-4 Bar) but higher than MTB. Optimal pressure depends on tire width, rider weight, terrain, and whether tubeless. Lower pressures increase grip and comfort on rough surfaces.
