![]() ![]() ![]() 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. The importance of tyre pressure on bicycles In this guide, we look at how to get the best tyre pressure for your riding style and conditions. The pressure that you choose for your bicycle tyres, whether it is a road bike, mountain bike, or hybrid, plays a huge part in comfort and safety. ![]()
