For general mixed-surface riding, 38–40mm tires in 700c are the sweet spot, balancing rolling speed with comfort and grip. If you ride rougher terrain or prioritize comfort, go 42–45mm. For bikepacking with 650b wheels, 47mm tires provide excellent cushion and traction. Run tubeless for puncture protection and the ability to run lower pressures (25–40 PSI depending on rider weight and tire width).
