How to see the bicycle tire pressure How to measure the bicycle tire pressure by hand
Before inflating a bicycle tire, you must first consider the tire pressure. Choosing the right tire pressure can make riding more comfortable, and insufficient or too high tire pressure may cause discomfort or even a blowout.
The tire pressure range is marked on the outside of the tire, and the common tire pressure units are psi, kpa, bar. mountain bike tires are generally in the range of 30 to 90 psi, road bike tire pressure is generally in the range of 80 to 130 psi or higher, due to different tire specifications, the specific tire pressure also varies. Advanced pumps are generally equipped with a pressure gauge, so you can observe the tire pressure value according to the gauge.
- Bicycle tire pressure how to measure by hand
Bicycle tire pressure, you can use your hands to test, with two hands pinch both sides of the tire, press hard, sense its hardness, if you can not press, indicating that the tire pressure is large, if you can easily press concave, you can rely on the degree of concave, roughly estimate how much tire pressure. Generally feel more hard, the big finger can slightly pinch on the appropriate.
Bicycle tires should be a little soft, not hard, high air pressure, adhesion is small, although the pedal light, but upside down, poor riding stability, easy to slip. The air pressure is small, although the adhesion is large, but the ride is laborious, but also may slip circle, pinch when the hard side, there will be about 3 atmospheric pressure, the front wheel air pressure should be slightly smaller than the rear wheel.
High TPI tires tend to be softer and can still maintain the maximum contact area with the ground when pressing through uneven surfaces, and will not allow vibrations to spread out. It should be noted that higher TPI woven mesh cover shells are thinner and require higher tire pressure to support.
- Bicycle tire pressure setting tips
The actual air pressure of bicycle tires should be set according to the specific riding environment, mainly depending on the relationship between tire pressure and grip, resistance, and riding comfort.
An increase in tire pressure within the allowable range of tire pressure means that the ground contact area of the bicycle tire becomes smaller, the grip and riding resistance becomes smaller, and the riding comfort decreases; a decrease in tire pressure increases the ground contact area of the tire, the grip and riding resistance becomes larger, and the riding comfort increases.
If it is a sunny day and flat road, you can make the tire pressure bias to the highest value, and pedal more easily; if it is a rainy day, bumpy road or easy to skid road, you should make the pressure bias to the lowest value, in order to increase the tire grip and riding comfort.
For heavier riders, to achieve greater traction need to properly increase tire pressure, pumping pressure, can effectively protect the rim, to prevent the occurrence of snake bite flat tire, especially in the rocky path, large drop and other rugged roads.
