Calculate the ideal tire pressure for your Gravel, MTB or Road bike tires. Optimize your performance, comfort, and safety on every ride.
Tire pressure changes everything: grip, comfort, speed, control. A few PSI in either direction affects how your bike feels and handles. Here is why it matters.
The right pressure helps your tires maintain consistent contact with the ground, improving traction when cornering, braking, or climbing, especially in wet or rough conditions.
Riding with pressure that’s too low increases the risk of pinch flats and rim strikes (when the tube gets pinched between the rim and an obstacle). The right setup protects both your tires and your rims.
Slightly lower pressure absorbs vibrations and small impacts more effectively, giving you a smoother and less fatiguing ride over long distances.
Higher pressure isn’t always faster. On imperfect surfaces, an optimized setup reduces rolling resistance by letting the tire adapt to the terrain instead of bouncing over it.
Correct pressure promotes even tire wear, helping your tires last longer and perform more consistently over time.
Especially in MTB and gravel riding, pressure that’s too low leads to hard impacts on rocks or obstacles, potentially damaging your rims.
Taking a few seconds to check your tire pressure before each ride makes a real difference in comfort, performance, and safety. Enjoy the ride.
Everything you need to know before you pump
To convert:
1 Bar is approximately equal to 14.5 PSI.
1 PSI is approximately equal to 0.069 Bar.
Our calculator provides results in both units for your convenience.You should adjust your tire pressure:
Conversely, too high tire pressure reduces comfort (you feel every bump), reduces grip (especially on wet or uneven surfaces), and can lead to excessive bouncing and loss of control.
Advantages: reduces pinch punctures, allows riding at lower pressures, improves comfort and grip.
Road:
Type of bike designed for speed and efficiency on asphalt. Generally uses thin tires and high tire pressure.
Gravel:
A versatile type of bike, somewhere between a road bike and a cross-country mountain bike, designed for riding on asphalt, dirt roads and tracks. Uses intermediate-width tires with variable pressure depending on the terrain.
Cross-country MTB (XC):
MTB discipline focused on performance and speed on hilly, technical but not extreme terrain. Light tires with pressure optimized for performance.
Trail MTB:
MTB discipline focused on versatility and fun, on trails more technical than XC but less extreme than Enduro. Tires with good grip/rolling properties.
Enduro MTB:
MTB discipline combining uphill phases and timed downhill stages on highly technical terrain. Requires robust tires with the right pressure for shock absorption and downhill grip.
Downhill MTB (DH):
Pure downhill MTB discipline on fast, highly technical terrain. Wide, resistant tires, with pressure optimized for shock absorption and maximum grip.
E-bike (electrically assisted pedal cycle):
Bicycle equipped with an electric motor to assist pedaling. The extra weight of the bike and the power of the motor often require slightly higher tire pressures and more robust tires.
