Rim selection?

Does Wheel Selection Increase Fuel Consumption?

The wheels add visual richness to the car and at the same time enable the engine power to be transferred to the wheel. The material and design of the rim used in changing a vehicle’s appearance is effective. In addition to the visuality, various points such as the driving quality of the car, road holding, engine performance and fuel consumption vary depending on the wheels.

Since it is an indispensable part of driving safety, the wheels to be attached to the car are of vital importance. The rim should be produced by a solid and reliable brand, and attention should be paid to the safety of the people traveling in the vehicle. As the traction power of the engine and the amount of fuel consumed changes depending on the wheels changed from time to time, it is useful to be careful.

What are the Effects of Wheel Selection on Fuel Consumption?

It is essentially recommended by many experts to continue using the vehicle’s original wheels. The most suitable rim is determined by the expert team that designed the car in accordance with the engine features, suspension and the concept of the car and presented to the consumer in a package. However, there is no harm in using only wheels with different visuals without interfering with the original rim dimensions of the car. In this case, using wheels with a larger diameter than normal has various effects on both fuel consumption and driving safety and vehicle comfort.

If a rim with a larger diameter than it should be attached to the car, this will directly affect the tires used. The sidewall thickness of the tires decreases and the rims remain more vulnerable to impact. The rim can bend and break due to a possible impact. This is a significant security risk. In addition, the wheel of the car gets heavier as the width of the tires increases with the rim. The maneuvering diameter also increases in this direction. For this reason, the clutch system of the car is adversely affected. The amount of fuel consumed also increases.


The acceleration of the car is reduced due to the use of larger rims. The vehicle cannot accelerate in the desired time due to the larger wheels fitted to the vehicles with low engine power. In this case, the main factor is the heavier wheel rim and the increase in the diameter of the wheel that the engine must rotate. Turning a wider rim requires more torque. Turning the large rim while the capacity of the engine is stable causes more fuel to be consumed. In short, big rim means more fuel consumption.

Which rim should I choose?

When choosing a rim, attention should be paid to both the power of the engine and the weight of the material from which it is produced. Although heavy rims cause more fuel consumption, the use of light rims is not suitable for every vehicle. When using lightweight carbon alloy wheels to consume less fuel, the vehicle with a powerful engine can be skidded and life-threatening traffic accidents may occur.

It is recommended by many people to use light metal rims as they consume less fuel. Therefore, light metal rims are generally used. Light metal type rims can be used with tubeless tires. This contributes to the vehicle being more stable and achieving higher steering control. Compared to sheet metal rims, aluminum and titanium rims weigh less. The overall weight of the car decreases, resulting in less fuel consumption in general.

What is a rim?

Rim is an important safety part in vehicles. It is located between tire and axle system. The tire is attached to fit around the rim. The power of the engine to rotate the tires is reflected on the tires by taking support from the rim. Therefore, wheels are considered among the main factors affecting vehicle speed, road handling, driving comfort, engine performance and fuel consumption. Rims vary according to the material they are produced from.

The rim types are as follows:

  1. Steel Wheels:
    This is the most common of all rims, mostly produced in black. It is also the cheapest and often referred to as factory fitted rims. It is among the strongest of all wheel types. During production, the sheet material made of steel is cooled in two parts and then welded together. They are not very pleasing to the eye compared to other rim types. In order to make the design look more pleasing to the eye, the same color wheel covers are produced in accordance with the black colored sheet metal rims.
    People no longer prefer to buy lighter and more attractive wheels. In addition, the steel rim is up to 80% cheaper than other rims.
  2. Alloy Wheels:
    Next are the alloy wheels. They replace steel rims and are more preferred than them. Alloy wheels are made of aluminum or magnesium, or both. They weigh less than steel rims. This less weight is a good thing for the rider; you get faster acceleration and minimal stopping motion. In addition, less weight provides less economical fuel consumption.

Another good thing about alloy wheels is that your car’s suspension is less stressed. Alloy wheels add a lot to the good looks of a car. Changing the wheels of a car from steel to alloy can bring out more beauty to the car than you ever imagined.

  • Aluminum Wheels: This type is called a steel wheel rims in Turkey. In the production of this rim, 90% aluminum and 10% silicon are used. With less than 1%, titanium and magnesium are added between other materials during the production phase.
  • Magnesium Wheel: It is not widely used because it requires very high costs to produce. It is a type of wheel mostly produced for vehicles participating in organizations such as Formula 1, where cost is not avoided.
  • Chrome Wheel: Chrome wheels are not as common as alloy and steel wheels. Chrome wheels are known for their shiny appearance. Chrome wheels are used for their aesthetics, not their performance. Chrome rims are easy to scratch and wear easily. It can be preferred because its price is relatively affordable compared to alloy wheels.

How to Enlarge the Rim?

Some people do not want to use the original tire size and rims that their vehicles have. They may want to change the look of the car by fitting larger rims. In this case, 3 methods can be mentioned for enlarging the rim.

In the first method to enlarge the rim, the age of the tire and rim is kept the same, while only a wider tire is used. In this way, only the tires are enlarged.
To enlarge the rim, the diameter of the rim is expanded by 1 inch. As the sidewall gets thinner, the diameter of the tire and rim becomes wider.
Finally, the diameter of the rim is expanded by 2 inches. It is not possible to expand more rims than this amount. Otherwise, the service life of the rim decreases, driving safety is lost and too much fuel is wasted.
