During traffic, there are many factors that affect fuel consumption, one of which is tires. Therefore, many users are concerned about how tires affect fuel consumption?

Tires have a big impact on fuel consumption

A report by the American Energy Association says that tires are responsible for nearly one-third of a vehicle's fuel consumption. In fact, 20% - 30% of fuel consumption and 24% of CO2 emissions2of road vehicles related to tires.

Tires affect fuel efficiency through the effect of rolling resistance. However, the relationship between rolling resistance, traction, and fuel economy is contradictory.

The US Energy Association also estimates that approximately 5-15% of a vehicle's fuel consumption is lost to reducing the rolling resistance of a tire. Another conclusion from the California Energy Commission shows that using low rolling resistance tires will help car owners save 1.5-4.5% of fuel.

Therefore, many tire manufacturers are in the process of researching tires that integrate both good grip and low rolling resistance. This is to bring users a smooth and safe driving experience.

In addition, the wheel alignment or the toe-in of the guide wheel also affects fuel consumption. When the wheel alignment is not suitable, the vehicle's direction of travel will deviate from the straight line, wasting fuel and causing danger when the vehicle participates in traffic.

For large vehicles such as trucks, a 1 degree misalignment of the wheel will cause the vehicle to deviate a few meters horizontally when the vehicle travels 1 km. At this time, to keep the vehicle running straight, the driver must hold the steering wheel.

This can easily cause tire slippage, which leads to tire wear and fuel consumption.

Be careful when tire inflation is not correct.

Nowadays, there are many drivers who still love to modify car tires, however, according to technical experts, they should not take the risk because it can be unsafe.

According to the customer service department of the centers, currently many car owners have a hobby of upgrading tires to larger sizes than the wheel. Larger tires will help them increase grip, enhance the appearance of the car as well as help reduce some small costs that some original tires can not do.

However, with larger tires also has certain disadvantages because if you do not choose tires with the right size for the old wheel rim, it can bring potential risks that affect the steering system, related processing systems and especially the safety of the car owner.

If you choose a tire that does not match the overall size, it will cause the tire to touch the fender during sharp turns or touch many other details on the vehicle, causing damage.

In addition, when the tire is large, it means the car has to carry 20-35% more air, significantly increasing its specific weight.

Not to mention large tires also have some disadvantages such as making the car sluggish when accelerating.

For the reasons mentioned above, according to engineer Le Van Tach's experience, users should not take risks when modifying tires.

Because according to manufacturers' recommendations, each car should only increase a maximum of 2 sizes in width and should not increase the tire diameter to ensure safety and avoid errors with the original car.

In addition, if you still love tire modification, you should choose good tires with good technology, high grip and rim grip. For tires, choose quality tires that are suitable for the rim. Choose a reputable tire brand.
