Road Bike Tire Pressure: The Complete Guide

Introduction

Tire pressure is one of the most important — and most overlooked — adjustments on a road bike. Incorrect pressure degrades comfort, performance, and increases the risk of punctures. Here's everything you need to know.

Why Tire Pressure Is Crucial

  • Overinflated: hard tire, less grip, vibrations, risk of blow-out
  • Underinflated: increased rolling resistance, risk of pinch flats, premature wear
  • Optimal pressure: maximum comfort, optimal grip, minimal resistance

Factors Influencing Ideal Pressure

  • Your weight: the heavier you are, the higher the pressure should be
  • Tire width: a wide tire (28-32 mm) requires less pressure than a narrow tire (23-25 mm)
  • Road conditions: wet road = slightly reduced pressure for more grip
  • Tire type: tubeless, tubular, or inner tube have different ranges

Recommended Pressure Chart

  • 23 mm tire, 70 kg (154 lbs): 7-8 bar (100-115 psi)
  • 25 mm tire, 70 kg (154 lbs): 6.5-7.5 bar (95-110 psi)
  • 28 mm tire, 70 kg (154 lbs): 5.5-6.5 bar (80-95 psi)
  • 32 mm tire, 70 kg (154 lbs): 4.5-5.5 bar (65-80 psi)

Check Pressure Before Every Ride

Tires naturally lose pressure (0.5-1 bar per week). Check and adjust before each ride with a floor pump with a gauge.

Conclusion

Tire pressure is a simple adjustment that has a major impact on your riding experience. Like choosing your David & Clément wall mount, it's a detail that makes all the difference.
