Do car tires have to be replaced with the original ones? What pattern is better for truck tires?

Tires are essential for vehicles to travel on the road. They have a certain service life and will wear out when on the road, so they need to be replaced regularly. So do car tires have to be replaced with original ones? How should we consider replacing truck tires?

Do car tires have to be replaced with original ones?

When replacing vehicle tires, it is not necessary to emphasize replacing tires of the same brand as the original ones. The tires used by the original vehicle are only selected by the manufacturer during vehicle manufacturing, which can meet the requirements of the product and have a lower cost. In other words, the original tires can be used as long as they can meet the basic technical requirements of the vehicle.

In the future, when we use our vehicles, we can choose some big brand tires with better performance and relatively higher prices. Different tires produced by different manufacturers have different focuses. For example, some tires have softer treads, lower noise, and relatively stronger grip. Some tire patterns are designed to be more suitable for off-road or for having stronger grip on slippery roads.

When replacing a tire, just select the wheel rim specification. If you must replace a tire, try to choose a tire with a similar wear amount as the tire on the same axle. At the same time, try to choose a tire with the same or similar pattern and other basic parameters. This can help ensure the braking and driving adhesion coefficient of the tire on slippery roads in rainy days.

In addition, it is recommended to replace tires on the whole vehicle or in pairs on the same axle. Because this can ensure the road adhesion coefficient of the tires on both sides, which is conducive to ensuring the stability of vehicle control. Generally, we will choose to put better quality tires on the drive wheels. For front-wheel drive vehicles, good tires should be placed on the front wheels, because the front wheels are both drive wheels and steering wheels. Good tires are an important guarantee for the safe driving of vehicles.

What pattern is better for truck tires?

Truck tires belong to the C3 series. Usually, the tire label contains three indicators, namely fuel efficiency, wet grip and tire noise. Fuel efficiency and wet grip are divided into 7 levels from A to G, with A being the best and G being the worst, because truck drivers need to decide whether to focus on fuel efficiency or wet grip based on their actual use environment. Usually, as a tractor for long-distance transportation, fuel efficiency is more important, while off-road vehicles should pay more attention to wet grip. As for fuel economy, the example on the far left of the figure below tells us that if the vehicle's fuel consumption is 30L/100Km, then if it is replaced with a Class B pattern with worse fuel economy, the fuel consumption will increase by up to 1.5L. The wet grip of the tire will directly reflect the braking distance, and poor grip means a long braking distance. It is usually difficult to find a tire with high fuel efficiency and good grip, because this requires a trade-off. Finally, the tire noise is very directly marked with decibels, which is very easy to compare.

What should you pay attention to when changing tires?

First of all, when you replace your car's tires, you don't have to use tires with the same pattern and brand as the original car. As long as the tire model is the same, it can be used.

The next step is to replace a tire.

There are certain requirements. The tread patterns of the new and old tires must not be much different, and they need to be replaced with tires with the same pattern as the old tires to avoid different treads and different degrees of wear on the tires on both sides, which may cause uneven braking force when braking.

Another thing is that if you replace two new tires, it is recommended that you install them on the front wheels for front-wheel drive models, because the front wheels are responsible for both driving and steering, and the degree of wear is greater than the rear wheels. In order to improve braking force and handling, it is better to install the new tires on the front wheels.
