Pro Tip

Adjust pressure by ±2 psi for personal preference, rim width, or specific trail demands.

If you’ve ever wondered what the correct tyre pressure is for your mountain bike, you’re not alone. Running tyres too hard reduces traction, while running them too soft can cause pinch flats or rim strikes. Getting it just right makes your ride smoother, safer, and far more enjoyable.

The MTB Tyre Pressure Calculator is a simple yet powerful online tool designed to give riders personalized tyre pressure recommendations. By entering a few key details—like rider weight, bike type, tyre width, terrain, and whether you’re using tubeless tyres—you’ll instantly get recommended pressures in both bar and psi.

This article will walk you through how to use the tool, provide a practical example, highlight its features and benefits, and answer common questions about mountain bike tyre pressure.

How to Use the MTB Tyre Pressure Calculator

Using the calculator is straightforward. Here’s a step-by-step guide:

  1. Enter Your Rider Weight (kg):
    Input your body weight. The tool uses this to calculate the right tyre pressure, since heavier riders generally need more pressure to prevent squashing the tyres.
  2. Select Your Bike Type:
    Choose between:
    • Hardtail – front suspension only.
    • Full suspension – both front and rear suspension.
    • Fat bike – extra-wide tyres designed for snow or sand.
  3. Pick Tyre Width (inches):
    Select the width of your MTB tyres. Wider tyres can typically run at lower pressures for better traction.
  4. Choose Riding Terrain:
    Options include:
    • XC/Gravel
    • Trail/General
    • Enduro/Downhill
    • Wet/Muddy
    • Snow/Sand
  5. Select Tubeless or Not:
    Tubeless tyres allow for lower pressures without pinch flats, improving grip on technical terrain.
  6. Click “Calculate”:
    The tool shows a progress bar while it calculates.
  7. View Results:
    You’ll see:
    • Front and rear tyre pressure in bar.
    • Front and rear tyre pressure in psi.
    • A helpful pro tip tailored to your setup.
  8. Copy or Share Results:
    With one click, you can copy your results to the clipboard or share them directly.

Practical Example

Let’s say you’re a 75 kg rider using a full-suspension bike with 2.35” tyres on trail terrain and you’re running tubeless.

When you enter these details and click “Calculate,” the tool recommends something like:

  • Front Tyre Pressure: 1.50 bar (22 psi)
  • Rear Tyre Pressure: 1.65 bar (24 psi)
  • Tip: “Adjust pressure by ±2 psi for personal preference, rim width, or specific trail demands.”

This way, you know exactly where to start before heading out. You can fine-tune pressures after testing, but the calculator gives you a science-based baseline.

Features and Benefits

🔧 Key Features

  • Custom calculations based on rider weight, bike type, tyre width, terrain, and tubeless status.
  • Results in bar and psi so riders from any region can use it.
  • Dynamic progress bar for a smooth user experience.
  • Copy and share options for saving or sending your setup.
  • Personalized tips depending on your chosen inputs.

✅ Benefits

  • Improved ride quality: The right pressure makes your ride more comfortable and controlled.
  • Better traction: Properly inflated tyres grip better on trails, especially in corners and rough terrain.
  • Reduced risk of flats: Avoid pinch flats by balancing low pressure with safety.
  • Time-saving: No more trial-and-error guessing—get a solid recommendation instantly.
  • Versatile: Works for different MTB disciplines, from XC to downhill and even fat biking.

Tips for Getting the Most Out of the Calculator

  • Always check your actual tyre sidewalls for manufacturer-recommended ranges before riding.
  • Use a reliable digital pressure gauge for accuracy. Floor pump gauges can be off.
  • Remember that conditions change—what works on a dry summer trail might not be ideal in winter mud.
  • Experiment slightly around the recommended value. Some riders prefer firmer tyres for efficiency, while others drop pressure for more grip.
  • Keep in mind that rim width can also affect optimal tyre pressure. Wider rims support lower pressures better.

Use Cases

  • Everyday riders: Quickly find safe, efficient tyre pressures.
  • Racers: Optimize performance for specific courses.
  • Beginners: Remove guesswork and start with confidence.
  • Fat bikers: Get correct pressures for snow, sand, or soft terrain.
  • Bike shops: Use as a quick customer tool to set up new bikes.

Frequently Asked Questions (FAQ)

Here are 20 FAQs to cover everything you need to know:

  1. Why is tyre pressure important for mountain biking?
    Correct tyre pressure ensures better traction, comfort, and safety while preventing flats.
  2. How does rider weight affect tyre pressure?
    Heavier riders compress tyres more, so they need higher pressures to avoid rim strikes.
  3. What’s the difference between front and rear pressures?
    The rear usually carries more weight, so it requires slightly higher pressure.
  4. Should I run the same pressure for XC and downhill?
    No. XC often uses higher pressure for speed, while downhill uses lower for grip.
  5. How accurate is the MTB Tyre Pressure Calculator?
    It provides an excellent baseline, but riders should fine-tune for personal feel.
  6. Can I use this calculator for road bikes?
    No, it’s specifically designed for mountain bike tyres.
  7. Why do wider tyres need lower pressure?
    They spread the load over more surface area, so they don’t require as much pressure.
  8. What if I use inner tubes instead of tubeless?
    The calculator accounts for this—tubes usually need slightly higher pressures to avoid pinch flats.
  9. What happens if my pressure is too low?
    You risk rim strikes, sidewall damage, or pinch flats.
  10. What happens if my pressure is too high?
    You lose grip, experience a harsher ride, and increase the chance of bouncing off obstacles.
  11. Do terrain types really matter?
    Yes. Wet, muddy, or snowy conditions benefit from lower pressures for grip.
  12. How do I measure my tyre pressure?
    Use a digital gauge for accuracy—pump gauges can be inconsistent.
  13. Why is the rear pressure always higher?
    Because most of your weight is over the rear wheel.
  14. Can I run the lowest possible pressure for maximum grip?
    Not safely—you need enough to protect rims and avoid burping tubeless tyres.
  15. Does suspension type affect tyre pressure?
    Yes. Hardtails often need slightly higher rear pressures compared to full suspension.
  16. Is the calculator useful for e-MTBs?
    Yes, but you may want to increase pressure slightly due to extra bike weight.
  17. What’s the difference between bar and psi?
    Both are pressure units: 1 bar = ~14.5 psi.
  18. How often should I check my tyre pressure?
    Ideally before every ride, since MTB tyres can lose air over time.
  19. Do fat bikes need special pressure recommendations?
    Yes, fat tyres often run extremely low pressures (0.25–0.6 bar) for soft terrain.
  20. Can I share my results with friends?
    Absolutely—the tool includes a “Share” button for easy posting.

Conclusion

The MTB Tyre Pressure Calculator takes the guesswork out of finding the perfect setup for your rides. By tailoring recommendations to your weight, bike type, tyre width, terrain, and tubeless status, it helps you achieve the ideal balance of comfort, grip, and durability.

Whether you’re racing downhill, grinding gravel, or floating over snow on a fat bike, this tool ensures you start with tyre pressures that make sense. Fine-tune from there, and you’ll enjoy smoother rides, more control, and fewer flats.
