Tire replacing is as inevitable as generational change. Tires eventually wear out, and to ensure a safe drive, new ones should take their place. Find out when to change car tyres, how to do it correctly, as well as how to extend their lifespan in order to change them as rarely as possible.

When to change car tires

There are two main reasons for a tire change: excessive tire wear and severe damage that may affect driving safety and vehicle handling. In countries with obvious seasonal changes, in which snow and ice are observed in cold period, tires are also changed at the beginning of every season. But this does not apply to India and other countries that have the same constantly warm weather as Indian. If you have to use your car in temperate latitudes or northern countries, you will have to change tires at least twice a year. If this is not done, tires will wear out faster and driving will be unsafe.

What affects tire wear

Tire wear is affected by four main factors:

- your driving style;

- weather and climatic conditions;

- quality of the road surface;

- tire care.

Accurate and attentive drivers have to change tires much less frequently. The main reason for wear is wheel bumps on all sorts of damage on the road, which are difficult to avoid if you are driving hard. In addition, if you do not slow down when cornering, often use sudden braking and start, this also leads to premature tire damage.

Heavy rainfall, extreme cold or heat also affects tire wear. Here, unfortunately, little depends on us. At the very least, try to use the car less often in bad weather.

The quality of roads is another factor that is difficult for us to influence. Poor road surface with an abundance of holes and irregularities will lead to tire damage many times faster than weather conditions. But, again, try to drive as carefully as possible, and you will minimize the damage from potholes.

On the contrary, the quality of tire care is entirely in our hands. Below we will describe what measures need to be taken to extend the life of car tires. In short, you need to inspect them regularly, do balancing and alignment, monitor the correct air pressure in tires, track tread wear.

What indicates the need to replace tires

To begin, make a rule to check tires monthly — this will save you from unpleasant surprises on the road. In addition, be sure to check conditions before a long trip.

Now let's take a closer look at signs that indicate that the tire needs replacing.

Each tire has so-called wear indicators. There are different types, but all of them are designed to signal the driver that the tire has lost properties necessary for safe driving. Why is it dangerous? To answer this question, you need to understand what is the purpose of the tire tread — a convex pattern on its outer surface. This relief is designed to provide optimum grip, as well as to divert water and dirt, making cars more stable. When the tread is erased to a certain level, road grip deteriorates, car becomes less manageable, which can lead to dangerous situations during driving.

Another important aspect that needs attention is uneven tread wear, for example, when it is wiped out more on one side than on the other. Or the tread of one wheel is erased stronger than the tread of another. The most common cause of this phenomenon is wrong wheel angle. Therefore, having changed a tire, be sure to subject your vehicle to alignment and balancing, two basic operations, providing not only comfortable driving, but also the best condition of tyre parts.

Other signs that show that the tire needs to be replaced are: swelling on the side of the tire, a puncture that caused blowing, damage longer than 6 mm, as well as damage to the bead area, area adjacent to a wheel rim. In all these cases, the tire must be replaced.

In addition to routine inspection, pay attention to behavior of tires while driving. If you feel a vibration, stop and inspect tires – most likely the problem is there.

How long can tires last?

Good tires, if used carefully, last about five years. Of course, it all depends on how often you use the car, so it’s better to focus on the car’s mileage. Experts say that tires need to be changed every 40-50 thousand kilometers. If they are of low quality, then every 10 thousand km. Watching your tires, you can determine approximate duration of their life. In any case, even the most reliable tires by the best brands with the most accurate use can not be used for more than 10 years. Also note that front tires are erased much faster than rear ones, mainly due to the fact that they make turns. If the car is front wheel drive, then they wear out even faster.

In any case, you should regularly check the health of tires, because they are the key to safe and comfortable driving.

How to change a car tire

Many drivers sooner or later ask themselves a question: shall I change my tyre myself or should I go to a wheeler? It is desirable that the replacement of tires is made by a qualified professional at a service station. He will do everything according to rules, in compliance with all necessary requirements. In any case, he is responsible for his work. In addition, the price for this service is not so high. If you do it yourself, then you are responsible for the result. However, experienced drivers wanting to save time and money change tires with their own hands. In some cases it is not possible to seek qualified assistance. Anyway, it is worth knowing how to independently perform this operation in order to be ready for any situation.

Removing old tire

So, if you decide to replace the tire by your own means, prepare a jack, a wrench, a pump, two mounting blades and be patient. First you have to get rid of the old tire. Using a jack, lift the automobile so that the wheel can be easily removed, but not too high. Remove bolts with a key, then pull the wheel towards you and, removing it, place it beside you so that the valve is on top. Remove the nipple and allow air to escape from the chamber. After that, you have to make a little effort and show some dexterity. Step with your feet on the wheel to separate the side parts of a tire from the wheel rim. Once you have succeeded, take both vanes and, thrusting them inside the tire, pull it out, beyond the limits of a disk. If you have tube tire, remove the tube. After that, release the second side of a tire, completely removing it. This operation requires great care, otherwise you may damage the disk.

Installing a new tire

Before you proceed to assembly of a new tire, examine it carefully, checking if it has any damage. Also inspect the disk – perhaps it needs repair or replacement. If everything is in order, get rid of the old balancing weights – you will have to balance the wheel anew. Check if the size of a tire and a disk match. This should be done when you buy a new tire in the shop (or purchase it online), but this will not be superfluous before installation as well.

When installing the tire, pay attention to special signs on a tire that will help you to do everything correctly. In particular, you will find arrows that indicate direction of rotation of a wheel, which is recommended by manufacturer. To simplify installation, some craftsmen advise to put some grease on board of the tire. But note: if you take too much grease, the tire may slip.

If you have successfully removed the old tire, you already have an idea of ​​how to put on a new one. It is necessary to do the same, but in reverse order: using the blades, first put on one side of the tire, insert the camera, if it is provided, then the second one. Remember that every time a tire is changed, the wheel must be rebalanced anew.

Things to remember when changing tires

When changing tires, you should always keep in mind mandatory rules, violation of which can lead to serious breakdowns.

1. First of all, buying a tire, pay attention to its size. It must exactly comply with specification of the car. The allowable difference should not exceed two percent.

2. Check important parameters such as speed and load indices. Recommended indices should be listed in the vehicle manual. You can use tires in which indices exceed recommended, but do not buy those which indices are lower.

3. It is also important to consider tire pressure. It must comply with recommendations of manufacturer. Note that these guidelines may differ for front and rear wheels. If you do not adhere to the norm, the car can lose stability and tires can be damaged.

4. It is advisable to change all 4 tires at once, even if only one or two are damaged. In extreme case, replacement can be made in pairs — first, the front wheels, which wear out faster, then the rear. But note that the interval between replacement of the front and rear tires should be small — not more than a couple of months. And yet remember, maximum driving safety is possible only if all four wheels are changed at the same time. In particular, identical treads on all four wheels are crucial. In extreme cases, they should at least have the same thickness.

However, there is an exception to this rule. You can replace one tire without changing others if wheels are new and car did not have time to drive with them for a long distance. As you understand, in this case, a newly purchased tire will hardly differ from the others, so the risk of losing control is minimal.

Considering the last rule, drivers sometimes have to remove tires in good condition from a car. You do not need to throw them away. You can use them for spare wheels. Or sell to other drivers so that they can use them on their spare wheels.

By the way, some drivers, in order to equalize front and rear tire wear, change their places from time to time. Thus, tires generally last longer and decay at about the same time.

Pay special attention to front wheels

You should pay particular attention to front wheels. As it was already mentioned, these tires become unusable faster, because when cornering they are exposed to increased loads. Therefore, tire replacement usually starts with them. Please note that tire wear is dangerous by itself, as it makes the car less comfortable to drive. But it can cause even more problems. If tires on wheels were used too much, it may cause the tire to break while driving. You can imagine consequences of such damage, especially if it happens on the track during high-speed traffic.

How to increase car tire life

If you follow all rules of using tires and try to drive carefully, your tires will last you long enough. High-quality tires may remain good for years.

First of all, when installing new tires, do not violate recommendations specified in instructions for your car. This refers to tire sizes, load and speed indexes, as well as air pressure inside it. Tire pressure should be constantly monitored. If it is lower or higher than the recommended, it will lead not only to poor handling of the car, but also to premature uneven erasure of rubber.

In addition to pressure, tire wear also requires constant checking. If the surface of wheels is erased unevenly, the tire will fail faster. By the way, uneven wear may indicate that wheels require alignment. You should also do balancing regularly, in particular after each tire change. Remember: alignment and balancing make the basis of good functioning and long life of tires.

Everything else depends on the quality of roads and on you. To make tires last longer, try not to violate rules of careful driving: choose speed according to type and condition of the road, try to notice defects of the road surface in time and slow down in advance, avoid a quick start and sudden braking.

Listen to extraneous noises and vibrations: timely repair of faults in tires will prolong their life.

Avoid such common operating errors:

● Simultaneous use of tires of different models.

● Using tires on damaged, warped or modified disks.

● Installation of tires which speed and load indices are lower than required by car manufacturer.

● Long ride with tires with pressure that is higher or, on the contrary, lower than acceptable.

● Using a spare tire of a different size at speeds above 80 kms per hour.

 

In summary, watch condition of your tires, do the alignment and balancing of wheels in a timely manner, follow manufacturer's instructions, drive carefully and do car tire replacement on time. Have a smooth ride!
