Free Tire Pressure Calculator
Calculate your ideal tyre pressure for road, gravel or MTB. Enter your weight and tyre size for an instant recommendation.
Why this calculator works
Strong enough for a first test ride, honest about what matters after that
Tyre pressure reacts strongly to a small set of inputs. That is why a simple public intake works well here as a starting point.
Fast starting point
Set weight, tyre width, surface, and tyre type to generate a practical first pressure baseline.
Built for refinement
Start here, then test small changes based on feel, terrain, and real ride feedback.
Build your pressure baseline
Start with the essentials first. Advanced options are there when you want to refine the recommendation further.
Inputs
What changes the result most
Surface
Move from smoother to looser surfaces as the terrain asks for more grip and compliance.
Explanation

Primary drivers
- Rider weight
- Tyre width
- Surface
- Tyre type
Secondary modifiers
- Open advanced options to include riding goal and bike weight.
Not covered here
- Internal rim width, casing construction, and wet conditions.
- Personal preference after a few validation rides.
Validate next
- Check front-tyre grip and comfort first on the next ride.
- Keep rear pressure slightly higher when the load or terrain feels harsher.
Validation notes
- Always follow the manufacturer's maximum pressure limits.
What changes the result most
- Weight and tyre width shift the baseline fastest.
- Surface and tyre type change how low you can safely go.
- Use the output as a starting point, then validate with ride feel.
Frequently asked questions
Short answers to the main questions about public pressure guidance.
How accurate is this calculator?
It gives a strong starting point based on weight, tyre width, surface, and tyre type. Always verify tyre and rim pressure limits afterward.
Why is front pressure lower than rear?
Most bikes carry more system weight on the rear wheel, so the recommended rear pressure is usually higher.
Can I save this recommendation?
Yes. Inside the dashboard you can save pressure recommendations per bike, wheelset, tyre setup, and riding goal.
