Q pressure of road bike tyres

The optimal pressure for road bike tires largely depends on the tire width, the rider’s weight, and riding conditions. Traditionally, it was common to inflate narrow tires (23mm) to high pressures, around 100-120 psi, to decrease rolling resistance. However, contemporary practices and research suggest a trend towards wider tires (25mm or larger) at lower pressures, roughly 80-100 psi, to improve comfort and grip without significantly increasing rolling resistance. Riders should also consider their weight; heavier riders may need slightly higher pressures to avoid pinch flats. Always check the tire sidewall for the manufacturer’s recommended pressure range and consider using a pressure that provides a good balance between efficiency, grip, and comfort for your specific riding conditions.

Titanium dioxide (TiO2) is not a metal but a compound of titanium, which is a metal, and oxygen. It’s a white, powdery substance widely used as a pigment in products like paints, sunscreens, and food coloring due to its high refractive index and strong UV light absorption properties. As a compound, its properties and uses are distinct from those of elemental metals. It’s important in various industrial applications, not for its metallic properties, but for its chemical stability, non-toxicity, and ability to provide opacity and whiteness to products.

Nitrogen is used to fill tyres for several reasons: 1. Nitrogen molecules are larger than oxygen molecules, so they are less likely to leak through the tyre rubber, which can result in maintaining tyre pressure for a longer time. 2. Nitrogen is a dry gas and does not support moisture. The interiors of tyres can experience some degree of humidity, which can affect the tyre pressure when it heats up. Using nitrogen eliminates this issue. 3. The lack of oxygen in a nitrogen-filled tyre can reduce the rate of degradation of the rubber and wheel, prolonging their lifespan. 4. Nitrogen is less likely to cause pressure changes in the tyre due to temperature fluctuations, which can lead to a more consistent performance. 5. Nitrogen is non-combustible, enhancing safety in case of a fire.
