    Crown Rubber shares your knowledge of bicycle tires

    Generally speaking, when describing the characteristics of a tire, it is roughly divided into several directions: rolling resistance, grip, road feeling, wear resistance, explosion protection, weight, and price.

    Tire characteristics

    Generally speaking, when describing the characteristics of a tire, it is roughly divided into several directions: rolling resistance, grip, road feeling, wear resistance, explosion protection, weight, and price. In addition, there are two other features that are often overlooked but important: power transmission and manufacturing quality. If you want to use "noun explanation" to explain these words, you may have fallen asleep before you finish reading, so I still use the "feeling" way to describe these characteristics, which is easier to read.

    Rolling resistance

    When the wheel starts to roll, you will want it to roll down and not slow down. Of course, this is impossible because it will face wind resistance and other resistance. In terms of the resistance of the bicycle itself, a small part of the reason is the resistance of the hub, and the other major part is the "rolling resistance" of the tire. The smaller the rolling resistance, the easier it is to maintain speed. In other words, you will speed up with the same effort. Needless to say, the smaller the rolling resistance, the better.


    When you are cornering or braking, the last thing you want to happen is slipping. At this time, the "grip" of the tire is a key. Even if it is linear acceleration, it will require grip when the force is strong. The bigger the grip, the better. The road feels uneven road surface, some tires will make you feel very upside down, and the whole body will be uncomfortable. Some tires are stuffy and have no feeling. Other tires make you feel the change of road conditions but not bumpy. . These feelings are collectively referred to as "road feelings", and you will want to have a comfortable road feel, rather than a road that is up to you.

    Wear resistance

    Bicycle tires are generally considered expensive. If you calculate the amount of rubber used in a unit of rubber, it is not more expensive than car tires. So of course you will hope that such expensive things can last longer, this is the responsibility of the tire "wear resistance". The better the wear resistance, the longer the mileage that can be used. Anti-blasting tires can be said to be the most common faults encountered in bicycle leisure sports, and in order to lighten the tire skin, there is often only a thin layer, which is not easy to withstand the puncture of stones, glass and branches. Most outdoor tires have an "explosion-proof" design to prevent foreign objects from piercing the mesh cover.


    Maybe you are chasing a lightweight one, and any spare parts on the bicycle must count the ten or twenty grams. Undoubtedly, the inner and outer tires are also a lightweight target. If you add up one car, you can get as much as one or two hundred grams. Regardless of the effect of reducing the weight of the tire, if you see the weight reduction on the whole vehicle, you may be able to pick up the money and buy lightweight tires.

    People who don't know the tires are just like those who don't understand the frame. If you don't know how to choose, buy the lightest one! Lightweight tires are incredible, and a weight difference can reach 50-100 grams. In fact, lightweight tires also bring a number of performance advantages, first accounting for some of the cheaper when climbing, and because of the lower inertia, it is easier to accelerate. The reason for the weight loss is mostly due to the thinner tire skin and mesh cover, and even the explosion-proof layer is omitted. The result is a more sensitive road surface response, a more comfortable road feel, and lower rolling resistance.

    However, what is the cost of lightweight tires? First of all, the tire skin must be very thin, so the wear resistance can not be too good, perhaps with a one or two thousand kilometers to see the bottom. Secondly, the explosion-proof layer can be saved at least 20 grams, and the road feel is better, but the tire skin is thinner and there is no explosion-proof layer, which means that the chance of you riding the half to stop at the roadside to change tires is greatly increased. Before you spend money on a lightweight tire, find out what kind of explosion protection measures it provides and whether it fits your riding environment. Don't let the broken tires detract from the fun of cycling, and also cause financial losses.
