Run-flat tires: chicken ribs or chicken?

As a car owner, no one will propose replacement advice to your car's tires than the repairman of a car 4S shop, and it will make you more responsive.

As long as the car moves, the strength of the tires and the safety of the owners are the heaviest.

For a car, the choice of tires is often the least likely to attract consumers' attention, and it is precisely one of the most cost-effective components of a factory. The selection of low-standard tires is often used by Korean-made and domestic-made cars that rely on price advantage to attract consumers. Of course, this has also led to the national eye-catching "Kumho Tire Incident."

I remember that in September 1996, the first day of the opening of the Shanghai-Nanjing Expressway, the author opened a joint venture production of the Audi 100, for the first time on the highway without a car, the first time to open the speed to More than one hundred kilometers per hour, for the first time, I felt the vibration of the car from excitement and tension.

Later, as seen in the newspapers, the vehicles running on the expressway required specialized high-speed tires, so all four tires were replaced by high-speed tires. After high speed, the jitters immediately disappeared and the car opened smoothly. The author also ventured to mention speed at 150 kilometers per hour and experienced a speed test at the time.

Shortly after the opening of Shanghai-Nanjing Expressway, many traffic accidents occurred. One of the main reasons is the puncture, and the sudden loss of control of the car leads to casualties. It was only then that people began to realize that the tires were so important for high-speed vehicles.

A tire is often equated with a lifebuoy, except that the former is on land and the latter is in water.

Nowadays, most cars are equipped with high-speed tires. Therefore, the news that a sudden tire burst caused a vehicle accident is much less than in the past. However, the topic of tire safety has never stopped.

Today's high-end cars have already begun to adopt a kind of car tire commonly known as “explosion-proof tires”. The real name of such tires should be “run-flat tires”. During the design and processing of tires, the sidewalls on both sides are thickened. After the tire leaks, the thick tire wall is used as the vehicle support, and the vehicle can be maintained at a certain speed and within a certain distance. Driving.

From the point of view of vehicle safety, gas-free tires are naturally safer than ordinary thin-walled tires. There are exactly two cars in the author's home, one with ordinary tires and one with run-flat tyres.

There was a sudden leak in the tires of both vehicles. The car with the ordinary tires accidentally passed through a tiled step once. The inconvenient interface of the tile resembled a cutter. The side wall of the tire was marked with a hole, and the car could not move and the tire was scrapped.

Cars equipped with run-flat tires, tires were punctured by tires, and were tire pressure alarms, which caused the author's attention and got off the bus to check. The four wheels did not feel strange at all. After entering the tire repair shop and using a special tool to remove the tire, it was found that the inner wall nails had penetrated the tread.

Two tire accidents, two experience, feeling that lack of gas to protect the child will be safer. Of course, such safety comes at a price: When you need a tire, you need to go to a store with special tools. The unloading of a tire must depend on a dedicated machine. It is impossible to remove from the hub by manual work. If it is a novice job, it may scratch the hub. The unloading of ordinary tires is a very easy and simple thing.

For tires of the same specification, the run-flat tires are about 40% more expensive than regular tires. For tires of consumables, this may give the owner more money, just to ensure more safety in case of rapid leaks at low probability.

The most important thing is that when using a flat tire, you have to endure some of the uncomfortable feelings caused by the car's hard suspension. This is like feeling like sleeping in a wooden plank bed.

As far as the author's personal feelings are concerned, the comfort of riding is naturally stronger with ordinary tires. The handling of vehicles is naturally a strong car with a lack of gas and tires, especially the conductivity of road feeling is quite sensitive.

Therefore, whether or not you choose to have a flat tire is not necessarily as simple as considering safety alone. If you want chicken or chicken, it depends on your needs and tastes.
