Polyurethane wheels with Hardness between 78A-86A Longboard Wheel PU wheel

The diameter of wheels is generally measured in millimeters (mm). Most skateboard wheels are 48mm to 75mm in diameter. The diameter of wheels will affect the sliding speed and starting speed. The small diameter wheels will slide more slowly, but the starting speed is faster, while the large diameter wheels will have the opposite effect.
1. 48-53mm wheels have slow sliding speed and fast starting speed. It is quite suitable for street skaters.
2. The 54-59mm wheels are suitable for skiers who like to do acrobatic movements, but also need to brush the street. They are also very suitable for beginners.
3. Wheels over 60mm, large wheels are generally used on Old School style boards and long boards. The big wheel can slide faster and run over the rough ground easily, but the starting speed is slow.
The width of the wheel floor contact surface is also important. The larger the contact area, the greater the weight will be distributed to the larger area, which means that the wheels are easy to be decelerated. Therefore, many wheels have rounded edges to reduce the width of the contact surface, so that the wheels can rotate more easily 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, and the wheel that is close to the width of the wheel itself will be locked more tightly when performing prop actions, such as the 5050 on the pole.
