Riding using a turbo trainer removes many of the benefits lower tyre pressure provides. Tubeless tyre: 38PSI (2.6Bar) Front / 40PSI (2.75Bar) Rear.Inner tube tyre: 50PSI (3.4Bar) Front / 55PSI (3.8Bar) Rear.Suggested tyre pressure for city bike tyres (35mm) - for a ≤70Kg rider: Tubeless tyre: 36PSI (2.5Bar) Front / 38PSI (2.6Bar) RearĪ hybrid bike tyre is similar in volume to a cyclocross tyre, so the pressures are also similar:.Inner tube tyre: 48PSI (3.3Bar) Front / 50PSI (3.5Bar) Rear.Suggested tyre pressure for cyclocross tyres (35mm) - for a ≤70Kg rider: Here's James with a thorough guide to figuring out the right tyre pressure for you. Tubeless tyre: 80PSI (5.5Bar) Front / 83PSI (5.7Bar) RearĬyclocross tyres are run at a higher pressure than mountain bike tyres, but a lower pressure than narrower road bike tyres providing the best compromise between grip and rolling resistance.Inner tube tyre: 90PSI (6.2Bar) Front / 93PSI (6.4Bar) Rear.Suggested tyre pressure for road bike tyres (25mm) - for a ≤70Kg rider: Road bike tyres are run at a higher pressure than mountain bike tyres, to reduce rolling resistance and the chance of 'pinch flat' punctures. Tubeless tyre: 26PSI (1.8Bar) Front / 28PSI (1.9Bar) Rear.Inner tube tyre: 36PSI (2.5Bar) Front / 38PSI (2.6Bar) Rear.Suggested tyre pressure for mountain bike tyres - for a ≤70Kg rider: The added volume in a mountain bike tyre means despite these lower pressures, it is less likely to pinch flat. Mountain bike tyres are run at a lower pressure than road tyres so that the tyre can conform to the terrain, and provide added grip. The best tyre pressure for your bike will depend on the kind of bike you have, the kind of tyres you have fitted and also factors like rider weight, road conditions and weather conditions. 'Pinch Flats' are not possible on tubeless tyres, because there is no tube to pinch.īecause of the risk of inner tube pinch flats, sometimes you need to run a slightly higher pressure than would be optimal in an inner tube set-up, to reduce the risk of puncturing. Tyres with inner tubes can be more subject to 'pinch flat' punctures if you run a low pressure this occurs when a large impact on the tyre causes the tyre's bead to pinch the inner tube and puncture it. When considering tyre pressure, you have to take into account whether you have clincher tyres fitted with inner tubes on your bike, or whether you have tubeless tyres. To achieve the best grip level and rolling resistance level, it is vital to get the correct tyre pressure in your bike tyres. Perhaps surprisingly, an over-inflated tyre also increases rolling resistance because it constantly bounces on the surface, rather than rolling smoothly along it. An underinflated tyre will provide too much contact with the surface, and therefore too much rolling resistance. Rolling resistance is how much friction occurs between tyre and surface the greater the friction, the greater the resistance. This means that an over-inflated tyre that bounces over a surface and rolls only on the central strip will not have good grip.
The more that a tyre can conform to and make contact with the surface that it is rolling over, the greater the grip level that it achieves. Tyre pressure has two primary impacts on how your tyres perform: first, it affects grip second, it affects rolling resistance.
