Two inline skate wheels with different durometer – 85A and 83A Digital Shore hardness tester. The Shore durometer is a device for measuring the hardness of a material, typically of polymers. [1] Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer ...

A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1]
The hardness (or durometer) determines the grip and slip of a wheel. Durometer is measured either on the A or D shore scales, where a higher number is a harder and more slippery wheel. Skaters may choose wheels based on their skating discipline and the floor type they are skating on (wood, sport court, concrete, etc.).
Urban skates Hockey skates. Inline skates are boots with wheels arranged in a single line from front to back, allowing a skater to roll along on these wheels. Inline skates are technically a type of roller skate, but most people associate the term roller skates with quad skates, another type of roller skates with a two-by-two wheel arrangement similar to a car.

Aggressive skate wheels are usually between 54 and 72mm, while anti-rocker wheels are between 40 and 47mm. The balance between hardness and grip is the key to an optimum skate wheel. Anti-rocker wheels are small, hard wheels designed for grinding rather than rolling.
Skateboard wheels come in diameters between 48 mm and 62 mm and are made of polyurethane, with a hardness above 80A. Some wheels will be made harder than measurable on the "A" scale and will have durometers up to 84B (about 104A). Skaters must make a compromise when choosing their wheels.
