About This Guide
This guide covers how gravel bike tire sizes are marked, Michelin's Tubeless Ready definition, and Michelin's published gravel and cyclocross pressures by tire width and rider weight. We have no official source for typical gravel widths or tread choices.
Gravel Bike Tire Guide
Choosing the right tires for gravel riding: balancing speed, comfort, grip, and durability across varied terrains.
Tire Widths (e.g., 700x35c - 700x50c)
Michelin says a bike tire size is given as ETRTO (for example 23-622), imperial (29 x 2.10) or metric (700 x 23C). We have no official source for typical gravel widths. Check your frame and fork clearance and the tire and rim makers' compatibility information.
Tread Patterns & Compounds
We have no official source for choosing a tread by surface, so check the tire maker's own description of each tire. Michelin describes its Gum-X compound as designed to optimize grip and rolling speed and its Magi-X compound as designed for maximum grip.
Tubeless Ready (TLR)
Michelin: a Tubeless Ready (TLR) tire can be fitted without a tube provided a tubeless wheel is used, the maximum pressure is not exceeded, sealant is added and the tire pressure is checked before each ride.
Tire Pressure (PSI/Bar)
Michelin's published gravel and cyclocross pressures, by tire width and rider weight: 33 and 35 mm, 40.6 PSI (2.8 bar) under 50 kg to 58 PSI (4 bar) over 100 kg; 40 mm, 34.8 to 52.2 PSI; 47 mm, 26.1 to 43.5 PSI. Michelin says the pressure recommended by the bicycle or tire manufacturer must be followed.
