73mm 78A PU wheels Longboard Skateboard wheel

The diameter of the wheel is generally in millimeters (mm). The diameter of most skateboard wheels is between 48mm and 75mm. The diameter of the wheel will affect the sliding speed and the starting speed. The small diameter wheel slides more slowly, but the starting speed is faster, and the large diameter is the opposite.

1. 48-53mm wheels, slow sliding speed and fast starting speed. Quite suitable for street skaters.

2. The 54-59mm wheel is suitable for skaters who like to do technical movements and have the need to brush the street. It is also very suitable for beginners.

3. For wheels over 60mm, large wheels are generally used on Old School-style boards and long boards. Big wheels can slide faster and easily run over rough ground, but start slowly.

The width of the contact surface between the wheel and the floor is also important. The larger the contact area will spread the weight to the larger area, which means that the wheel is easy to be decelerated, so many wheels treat the edges into rounded corners to reduce the width of the contact surface, making the wheel easier to rotate and slide. Faster.

The smaller the width of the contact surface, the easier it is for the wheel to slide sideways, so it is not suitable for novices. The width of the contact surface is very large, which is very close to the width of the wheel itself. When making props, such as the 5050 on the pole, it will lock tighter.
