Which manufacturer’s tires will last longer? Tires are made of rubber and have a limited life.

The life of a car tire is determined by the following two factors. The first is when the groove disappears due to rubber wear. The other is when the rubber itself deteriorates and cracks.

This is a problem that is directly related to the maintenance cost of the car because it has to be replaced when the tire reaches the end of its life.

Although each manufacturer displays the durability of each tire, it cannot be said that it is actually durable up to tens of thousands of kilometers for years.
This is because the lifespan changes greatly depending on how you ride and the settings of the car.

In this article, we will introduce how to ride to extend the life of tires, alignment adjustment and tire rotation methods, and which manufacturer’s tires have a long life, which is directly linked to the maintenance cost of the car.

How do you drive a car to shorten the life of the tire?

First of all, how to drive a car. For example, as a run that shortens the life, if you repeat sudden start and sudden braking, run a lot on gravel roads, repeat cornering that speeds up like ringing tires, of course, rubber will be compared to normal running. The amount of reduction may be fast, or a biased reduction may occur.

In addition, if there is no indoor garage and the rubber is exposed to direct sunlight without waxing, the rubber will deteriorate faster.

What is a car setting that shortens the life of tires?

ire alignment is the main setting that affects the life of a tire.

For example, if there is a toe-in or toe-out, the road surface and the tire will rub against each other by the difference between the direction in which the tire rolls naturally and the direction in which the car travels, and the tire will wear out faster. Also, if you have a camber angle, the inside or outside of the tire will be reduced first.

This is called uneven tire wear.

It’s the story of Alfa Romeo 156 that I was driving (I’m sorry it’s an old story more than 20 years ago …) Alfa at that time was toeed out to make the steering response quick!

In addition, because it is a driving wheel (it is Front-engine Front-drive car), the front tires wear out quickly, and when running at high speed, the inside of the tires peeled off and started to make a noise when it hit the body, and the dealer who rushed in hurriedly said, “Oh, the tires have worn out so suddenly!? ”I was surprised.

In this way, if you are seasoning the tire alignment settings for the purpose of changing the ride quality, you need to pay attention to the reduction of tires.

Also, even if you do not make any unusual settings or cause an accident, the alignment will be slightly out of alignment after riding for many years, so regular adjustments will extend the life of the tires. It seems to be important in terms of meaning.

For details on alignment adjustment to prevent uneven wear, see the following page.

There is also such a method! Extend tire life with tire rotation.

Another way to extend the life of a tire is with tire rotation.

This is a method to prevent uneven wear by swapping the front, rear, left and right tires. Roughly it seems to be better to go to the prospect of 5000km.

It seems that even AUTOBACS can handle everything from measurement to adjustment.

Tire manufacturers are developing tires that have a longer lifespan.

While assuming that the service life will change depending on how it is used, each manufacturer is eager to develop tires that will last as long as possible.

For example, a tire with low rolling resistance, called a fuel-efficient tire, loses rubber slowly and has a longer life.

Dunlop eco-tires have a reputation for durability.

Yokohama tires also have the same performance as Dunlop.

Bridgestone is the largest manufacturer in Japan, but if you use special rubber, it may decrease slightly faster.
But don’t worry, it’s not extremely short-lived.

Therefore, if you are a major manufacturer like the one above, you should be able to obtain long-life tires that incorporate the latest research results of each company, regardless of which brand you choose.

Cheap tires are cheap because they have a short lifespan, which is a matter of course.

On the other hand, we often see cheap imported tires these days, but imported products may have a short life.

In particular, studless tires cure quickly and reach the end of their life in about half of Japanese manufacturers.

There is no problem for those who buy a new one in an early cycle, but otherwise it is not recommended.

If you drive one car for nearly 10 years, you will have to buy a new one or two on the way, but since it is a great opportunity, if you choose a high-quality one, the ride comfort and quietness will change significantly, and you will ride a different car. You will be impressed.

Why should you choose a tire made by a Japanese manufacturer?

It is often said that any manufacturer is fine because the performance of recent tires has improved.

But if you’re wondering which manufacturer’s tire to choose, you should choose a Japanese manufacturer’s tire.

Every manufacturer is tested in the country of manufacture.

Japanese manufacturers make tires that fit Japanese roads, and overseas manufacturers test on overseas roads and make tires that match them.

If you run abroad, overseas tires are good. However, if you drive on Japanese roads, you should choose tires from Japanese manufacturers.

The major tire manufacturers in Japan are as follows.

• Bridgestone
• Yokohama tires
• Toyo tires
• Dunlop

Bridgestone, Yokohama tires, Dunlop, etc. are manufacturers that are often seen in commercials.

It is said that there is no big difference in performance and quality between manufacturers, so it is better to decide based on your impression, taste and price regarding your manufacturer.

They are focusing on the development of “eco tires” !

Recently, each company sells fuel-efficient vehicles such as hybrids, PHVs, and PHEVs.
Tire manufacturers are also focusing on developing tires that improve fuel efficiency.

Low fuel consumption and no use of petroleum resources also saves gasoline, so it is a nice development for us in the car!
Of course, it has been developed so that its performance does not deteriorate, so the price will be a little higher. However, if fuel economy improves, the cost can be recovered.

About 10 years later, about 80% of cars may be PHV and PHEV plug-in hybrid cars.

By that time, the performance of eco-tires has improved, and it is possible that most cars are equipped with eco-tires.

When choosing tires, you should also consider eco-tires!

Summary

You don’t have to say that “higher prices are better tires”.
On the contrary, if the price is low, there may be only reasonable performance.

However, not all cheap things are bad, and you can see that the way you drive your car also affects how tires are worn and fuel economy.

For example, if you buy a tire that doubles in price, it doesn’t mean that it will last twice as long.
Performance will improve, but whether it will last longer or not will be another matter.

However, there is one thing that can be said for sure.
“If you buy from a Japanese manufacturer, you won’t miss it!”
