Hybrid wheels come in various sizes. Some bikes use 700c road wheels while others use 26” and 27.5” wheels commonly found on mountain bikes.

Perfecting the tyre pressure on your mountain bike is no easy feat. So many factors affect the pressure you should put in your tyres before you ride. From trail conditions to rider weight, the subject of tyre pressure is where science and dark art combine. This is an ANSI-rated B40.1 gauge that falls under the Grade B category of international standards. It has a pressure range of 0-160 psi, which is well within the usual road bike inflation range. Its high accuracy is complemented by its bronze Bourdon tube, which allows for precise needle movement that’s unaffected by external factors. It also has an integrated bleed button for finer adjustments to overinflated tires. 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. You can find more guidance in our bike tyre buyer’s guide. FAQs Why do some riders choose to run lower pressures in their mountain bike tyres?Before we delve deeper into all the factors at play, here is a rough starting point of suggested tyre pressures for a typical 80kg rider (including kit), riding a trail bike in typical UK conditions. Rolling resistance– when tyres roll along a surface, they create friction. The wider the tyre, the more friction that’s created which slows you down. Of course, this friction also helps a tyre...

A good mini pump belongs in your luggage on every bike ride. In the event of a flat, it often decides your next move for the day. Modern hand pumps are very handy and you'll barely notice they're there. Pay attention to the specified pump volume when buying. If you see "HP" in the product name, it stands for “High Pressure”. It is suitable for narrow tyres that are ridden with high pressure, for example on road bikes. "High Volume" pumps can be used for all wide tyres with a lot of volume. You'll have air in your tube again in no time.

Tyre pressure guide for mountain bikes

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.
