Rim Size: Friend or Foe of Car Speed?

Many people believe that the bigger the wheel, the faster the car goes. Is it really so? Let's understand how the size of the wheel rims affects the speed of the car. Also, your car can become more stylish and comfortable if you use tuning accessories, a large assortment of which is available in our online store.

Effect of disk size on speed

• Weight: Larger discs are heavier, so the engine needs more power to spin them. This leads to a decrease in acceleration and, indirectly, the maximum speed.
• Wheel diameter: the larger the wheel diameter (the sum of the disc diameter and the tire height), the greater the distance the car travels in one revolution of the wheel. In theory, this could lead to an increase in top speed in high gears.
• Tire profile: low-profile rubber (wide and thin) provides better grip on the road in turns, but at the same time increases rolling resistance.

Perfect balance

In terms of speed, the balance between disc size and tire height is important.

• Large rims + low profile: excellent option for improving handling at high speeds, but can lead to a decrease in acceleration dynamics.
• Smaller wheels + high profile: provides good acceleration dynamics and comfort, but handling at high speeds can be less sharp.

What else to remember:

• Manufacturer's recommendations: the car manufacturer indicates the size of the discs, which is optimal for a specific model, taking into account its power and weight.
• Driving style: fans of quick starts from a standstill are better suited to smaller diameter discs with a high tire profile.
• Car condition: faulty brakes, worn suspension elements or incorrect tire pressure - all this negatively affects speed, regardless of the size of the wheels.

Conclusion

The size of the wheels affects the speed of the car indirectly, affecting acceleration and handling. The choice of disks depends on the driving style, the power of the machine and the manufacturer's recommendations. Do not chase the largest possible size, strive for a balance that will provide you with a comfortable and fast ride.
