For any cyclist, inflating bicycle tires is a common thing. Many people already know what to do, but most people have not conducted in-depth research on inflating tires. Next, we will introduce the seemingly sparse thing about tire inflation from a professional perspective.
Why do I need to refill bicycle tires?
The previous tires were solid, and the riding experience was not good, so the emergence of hollow tires in the back gradually replaced the solid tires, because the air inside it acts as a spring, providing you with a suspension and making the tire conform to the terrain, thus providing Better traction and grip. Inflating tires is to improve the experience when riding a bicycle. Inadequate tire pressure will have some negative effects on the riding style of the bicycle, and may also make the bicycle more prone to flat tires.
How do tires keep air?
Most bicycles have an inner tube. This is a circular airtight tube inside the tire, with a valve for inflation that can be seen on the outside. You may have heard of tubeless tires, which have no inner tubes, but use special rims and tires to seal the air without using inner tubes. These usually require the use of a sealant inside, which is a liquid that will block any place where air escapes. Tubeless tires are more common in mountain bikes, but the technology is migrating to road bikes.
Tubeless sealants can also block punctures, and the absence of a tube means that the risk of flattening is much lower-that is, it can cause punctures when your inner tube is squeezed by the edges. Therefore, tubeless tires can be run at lower pressures to improve comfort, speed and traction.
Running tires under excessively high or low pressure can be dangerous and have a negative impact on the operation of the bicycle.
If the tire pressure is too low, the tire may wear prematurely. Excessive bending of the sidewall can cause the carcass to crack and the tire to become brittle. This may eventually cause a flat tire. Too low pressure will also increase the likelihood of tire puncture, and may even cause the tire to roll off the rim if you are cornering at high speeds (internal pressure keeps the tire on the rim). On the contrary, excessive pressure may cause a flat tire. This pressure can also squeeze the wheels, because if the pressure is too great, the pressure on the wheels will be too great. All in all, low pressure may make it difficult to drive tires under load. Your bike will feel uncontrollable and it will travel very slowly.
On the other hand, excessively high pressure will result in reduced grip and uneven driving, which may cause fatigue and thus affect operation.
Why is my tire flat?
There are two possible causes of tire leaks. Over time, the tire may puncture or deflate. Another reason is that the tire experiences puncture. Since the inner tube is not completely sealed, all tire systems leak air slowly. For example, standard butyl tubes hold air well compared to lighter latex tubes, which leak relatively quickly.
The old tube leaks more air than the new tube, so if you haven’t changed it in a long time, you need to check the tires.
The way to check the tire pressure is to inflate through the tire inflation pump. There are some inflation pumps on the market that are not traditional manual pumps, but electrically driven electric pumps. Some good tire pumps can also detect tires. Pressure, so that you can know the air pressure of the bicycle tire more clearly. At the same time, the current tire inflation pump is already a small portable air pump, which can be easily placed on the bicycle bottle cage. In case of outdoor travel, if you encounter special circumstances, use Coming to the emergency is a very good choice.
