What tire pressure should I run on a cyclocross bike?

Tire pressure for CX varies dramatically by conditions, rider weight, and tire setup. Typical ranges are 25–35 psi for tubeless setups and 30–45 psi for tubular or clincher setups. Lower pressures provide more grip and comfort on loose terrain but increase rolling resistance on hard surfaces and risk rim strikes. In muddy conditions, slightly higher pressure helps the tire cut through to find traction. On sand or dry hardpack, lower pressure maximizes the contact patch. The ideal pressure often changes during a race as conditions evolve — many elite riders choose a compromise pressure that works across all course sections.
