Tire rotation: Car maintenance tips are important that many Vietnamese drivers do not notice


Most drivers don’t pay much attention to the tires of a car because it’s a coarse part and doesn’t have any high technology. However, tires are of paramount importance to safety and driving experience because they are the only part of the car in contact with the road surface. Indifference to this part can cause serious traffic accident at any time.

Every part in your car needs regular maintenance and most will need to be replaced at some point. Among the parts most prone to wear are the tires. They will, of course, need to be replaced at some point, but you may not have to change the tires early by rotating the tires so they wear evenly. The following article will provide information on the tire turnaround times and how to do this for vehicles with different powertrains such as: 4WD, AWD, FWD and RWD, among other helpful tips.

Signs of unusually worn tires and their significance

Different problems lead to different types of tread wear. By checking the tire wear, you can get important information about the problem with your car.

Common tire wear patterns

The three most obvious types of tire wear are middle wear, edge wear, and inner / outer edge wear. Wearing between tires is caused by the tire being over-inflated for a long time, resulting in constant contact with the tire center of the tire. Tread wear on both the inner and outer edges means that the tire is deflated frequently, causing these sections to come into contact with the road most. If the tire wears a lot on the inside or outside edge, it means the car has an alignment problem.

Two other common tire problems are irregular wear and side blistering. Uneven tire wear, caused by uneven up or down movement or bounce of the wheel This phenomenon is more common in older vehicles with aging suspension. If left untreated, the tires will wear prematurely and interfere with the tire’s contact with the road, which will significantly affect the vehicle’s steering and braking ability.

Another common tire problem is blistering on the side walls. A lateral bulge is often the result of a physical impact, most likely from a collision with a large pothole. The tire’s inner lining is damaged, creating a small hole or tear in the side wall. At that time, air can enter the structure of the tire and create a bulge.

This affects the strength of the tire wall. If not handled in time, a bulge on the side wall can lead to a flat tire or a tire explosion, both of which can cause serious accidents.

Car tire explosion can lead to serious car accident

Sometimes, a bulging on the side wall can be caused by structural damage to the tire. This can be the result of spontaneously damaged old tires, even if you rarely drive.

Tires are made of natural rubber, neoprene and other chemical compounds. If you stretch the rubber band for a long time continuously, it will appear small cracks all over the place and eventually cracks. The same goes for an unused rubber strap: when you stretch, it cracks and breaks.

The same goes for wear on automotive tires. The more you drive, the faster the tires will degrade. Even if you rarely drive a car, the longer your tires are inactive, the faster they age and damage.

Benefits of reversing car tires

Depending on whether your car is front-wheel-drive, rear-wheel drive or two-wheel drive, each tire will wear at a different rate due to different usage. In front-wheel drive, for example, the front wheel has to work more than the rear wheel because of the steering, braking and weight of the engine and front wheel.

Periodically rotating the tires will help all four wheels wear evenly, thus extending their service life a little longer as well as improving performance and driving safety.

How often should you rotate the tires?

Experts give many recommendations about the tire rotation time. The average time is at least every six months. Some tire companies recommend that users rotate tires every 10,000-12,000 km.

Of course, how often to rotate the tire every time depends on many factors, and if your tire tends to wear out faster than average, turn the tire earlier for safety and performance. operation of the vehicle.

Tire rotation layout for different drive systems

Two-wheel drive, front and rear wheels will have different engine and gearbox arrangements. They are used in certain driving situations to ensure safety and to help the driver control the vehicle more easily. Each system treats the power transmitted to the tires in different ways, so each system has its own tire wear and therefore these cars need their own tire reversing layouts.

Tire reversing layouts are commonly used in cars today

According to the Tire Industry Association, there are three types of tire reversals that apply to most of today’s AWD (2-wheel drive), FWD (front-wheel) and RWD (rear-wheel) vehicles, as they are equipped with the front and rear tires are equal in size. Before you do a particular tire reversal, check your manual to see if your tires are one-way, that is, they only rotate in one direction for normal operation.

Two-wheel drive wheel drive (AWD)

AWD is a two-wheel drive system that is always ‘on’ and it changes the power transmitted to each wheel for the vehicle to balance and operate optimally.

Subaru’s advertising campaign summed up the AWD’s advantage very well: “transmitting power from sliding wheels to traction wheels”. When traction is lost, power from the engine is transferred from the wheel to the other wheels, helping the car quickly regain grip, thereby improving fuel economy.

It’s also important to note that while many think AWDs tend to have more evenly worn tires than other types of drivetrain, this doesn’t mean the car doesn’t wear uneven tires and can be neglected. .

Vehicle owners should regularly monitor the tire condition

This is because the inherent weight difference between the front and rear of any car can affect tire wear. Second, the active two-wheel drive system doesn’t always drive all-wheel drive. Remember that depending on the selected drive mode and driving conditions, the gearbox and electronically controlled differential can switch power between the front and rear wheels, creating uneven wear.

For AWD vehicles, the optimal tire reversing layout is diagonal: move the tire from front right to rear left, front left tire to rear right, rear left to front right, and from rear right to front left. Another way to remember this is that what is in front will be behind, what is on the right will be on the left, and vice versa.

Front wheel drive (FWD)

Although 4WD and AWD vehicles have recently become more popular, most cars on the road usually have front-wheel drive, meaning the power of the engine is only transmitted to the front two wheels.

One advantage of the FWD vehicle is the ability to grip the road better when going uphill, because the force is all located in the front wheel. However, this also means low traction in normal driving situations: if either of the front wheels loses traction and slips, the car has only one wheel left to grip the road.

For FWD, swap the front tire for the rear right-hand position on the same side, i.e. right front tire to rear right tire and left front tire to left rear. Then, reverse the rear tire: move the right rear tire to the front and left and the left rear tire to the front and right.

Rear wheel drive (RWD)

When you press the accelerator in a rear-wheel drive vehicle, force is applied to the rear wheels, maximizing the vehicle’s efficiency when accelerating. That is, the rear wheel provides the force for the vehicle to move, while the front wheel determines its direction.

For RWD vehicles, the tire reversal layout is the same as for FWD vehicles but vice versa. Move the rear tires forward, that is, the left rear tire to the front and left and the right rear tire to the front right. Then, move each front tire to the rear opposite tire, which is front-right to rear-left and front-left to rear-right.

How long are the tires used?

Like other parts of your car, the answer differs depending on the tire quality, the driving conditions and how you use them. However, there are still general estimates for the average life of automobile tires.

Tire

Car tire life depends on many different factors

Experts all agree that a tire can travel 80,000 km in normal driving conditions, equivalent to about 3-4 years of driving. Even so, many car owners report that their new tires or replacement tires can only run 30 to 50 thousand kilometers.

While you don’t have to spend a lot of money to buy premium tires, it’s best to research and choose some quality tires instead of the cheapest on the market.

How do I know the age of my tire?

You can determine the age or year of manufacture of a tire by looking for the Tire Identification Number (TIN) on the side wall of any tire. TIN will be the last group of digits in a longer alphanumeric group after “DOT”.

tire parameters

Important information about a tire is usually printed on the tire side

An example of a DOT code is: DOT Y9RJ FPUU 2620. Each group of digits is separated by space. The last group of digits for this tire consists of 4 digits, meaning that the tire is manufactured after 2000. Specifically, it is produced in the 26th week of 2020, which means that the tire is new. Another example of the DOT code is: DOT JI3P FUM0 137. The last group with 3 digits is “137”, indicating that the tire is manufactured by the 13th week of 1997.
