Have you ever noticed how many screws are on your favorite wheels? Careful car users will find that in daily life, a family car with a price of about US$16,000.00 is fixed with four screws on the wheels, while medium and large cars such as SUVs basically require five screws to fix them. Some luxury models even have six screws. Therefore, this has also made many car owners wonder: “Does the higher the number of wheel hub screws indicate the higher the grade of the car?” “Will the number of wheel screws affect driving safety?”
Let us briefly explain it for everyone today.
Does the number of wheel screws determine the grade of the vehicle?
The wheels of Mercedes-Benz S450L are fixed by 5 screws.
Mitsubishi LANCER (CY4A) uses a 5-hole design
The Lingyue V3, also from Southeast Motors, uses 4 wheel screws.
The 2012 Volkswagen CrossPolo wheels also have 5 screws.
In short, there is no direct relationship between the grade of the model and the number of hub screws.
In fact, there are only 5 screws on the wheel hub of a luxury car like Rolls-Royce, while the number of screws on the wheel of some large tool carts and buses is as many as a dozen. In order to facilitate the replacement of the wheel, F1 racing car only uses 1 screw. Therefore, it is unscientific to use the number of screws to determine the grade of the car.
Does the number of wheel hub screws affect driving safety?
The answer is also no. Of course, the number of screws on the wheel is not necessarily related to the safety of the car. This mainly involves various physics, mechanics, engineering principles such as axial force, thread torque, screw mechanism, friction coefficient of end face and so on. Therefore, the number of screws is not arbitrarily designed. Usually, how many screws are used in consideration of the weight, design shape and power parameters of the body. Before leaving the factory, cars will go through rigorous fatigue tests, bench tests, road tests and other test items. As long as they pass the test, the strength of the car, whether it is 4 or 5, will not affect driving safety!
In short, in fact, the number of screws has no direct relationship with the grade and safety of the car.
What is the factor related to the number of screws? The number of screws can directly affect the PCD value of the wheel,which affects the range of options for this car when upgrading the wheels.
