Guide to Skateboard Wheels

Skateboard wheels are small rigid wheels that propel skateboards. They are attached in pairs to the bottom of the skateboard, mounted and held in place by special axles called trucks. They are usually made of polyurethane, a type of hard rubber, and range in size from 48 to 100 millimeters.

Skateboard wheels also come in various degrees of hardness, measured in the durometer A scale. The softest wheels are about 75a, and the hardest are at the top of the scale at 99a. Some wheels are labeled 101a or higher, although this is inappropriate because the scale only goes up to 100. Such measurements are usually done on the B or D scales, which are more accurate and cover a wider range of hardnesses.


Types of Skateboard Wheels

Street Skateboard Wheels

Street skating wheels are the smallest type of wheel, measuring 48 to 55 millimeters. They are also relatively hard, which prevents them from absorbing energy and slowing down. They are useful for performing skating tricks, such as flips and ollies (a type of aerial stunt).

Vert Skateboard Wheels

Vert skating wheels are designed for vert skating, which involves jumping and landing on ramps. They are about 55 to 65 millmeters across, allowing faster and more sustainable speeds than street skating wheels. They are one of the hardest types of wheels available, mainly because they are used exclusively on ramps.

Slalom Skateboard Wheels

Slalom skating wheels are used in slalom racing, a sort of obstacle race where the skater skirts around a trail of cone obstacles. They are larger than vert wheels at 60 to 75 millimeters, enabling them to sustain maximum speeds for longer periods. They are usually softer to enhance grip on tight turns.

Longboard wheels

Longboard skateboard wheels are designed for longboards, which are used for cruising and transport. They range in size from 65 to 100 millimeters, providing a stable and comfortable ride. They usually have hard plastic cores, since solid polyurethane would make them too thick and heavy.

Choosing Skateboard Wheels

Durometer: Choose a skateboard wheel with the right durometer for your skill level. Softer wheels are best for beginners and children, because they do not easily trip over rocks or bumps. For adults and casual skaters, a good all-around durometer is about 97a – this will work on most street and skate parks, and even some pools and ramps. Wheels above this durometer are too difficult for the average skater and are best left to the pros.

Size: Choose the appropriate wheel size for your body size – the smaller you are, the smaller yout wheels need to be. For children and teens, 52 to 55 millimeters is a good range, while 56 to 60 millimeters can work for bigger riders. Anything bigger than 60 millimeters is usually a specialty wheel, and will not be suitable for most parks.
