While making this MTB tire calculator we took into account the most most common factors: rider weight, tire diameter, rider experience, tire width, tubeless/tubes, terrain roughness, and riding type. We then cross-referenced the data from top tire manufacturers with our own real-life riding experience, aiming to offer the most accurate mountain bike tire pressure calculator we could.

PLEASE NOTE: Our online mountain bike tire pressure calculator can be used to estimate an optium tire pressure. This estimated value provides a good basepoint for you to make your own adjustments to, depending on the conditions, your suspension setup, frame geometry, rim width, brand/model of tire, and other personal preferences.

Values provided here are purely estimates, and we accept no responsibility for any issues that may be encountered. If after using this calculator you are still unsure if your tire pressure is correct for you, please check with a qualified bike mechanic.
