Skateboard wheels vary in color, size, and durability. Skateboard wheels are most commonly made of polyurethane. The diameter and durometer of the wheel affect the way the board rides. The diameter and durometer are a matter of personal preference and skating style.
Diameter is the size of the wheel when measured from top to bottom. All Skateboard wheels are measured in millimeters (mm). The smaller the number, the smaller the wheel. Smaller wheels are slower; bigger wheels are faster.
Durometer measures the wheel’s hardness. Harder wheels are faster; softer wheels are slower but have better grip.
Skateboard wheel durometer is usually measured on a Durometer A Scale which goes from 1-100 to measure hardness. Some companies use the B Scale which measures 20 points lower, allowing the scale to be extended by 20 points for harder wheels. For instance, an 80b durometer is the same as 100a durometer. These skateboard wheels have a larger and more accurate range of hardness. The average wheel durometer is 99a.
