One of the major factors affecting your skating performance besides the skate boots are the wheels. They are available in various sizes, core designs, profiles and have different durability ratings, ranging from 74A (softest) to 94A (hardest). Each of those parameters is designed to suit a specific skating style, speed, surface, the skating level and body weight of a skater. Therefore, you need to understand these properties to be able making a right choice.
Size: The size of a wheel is the outside diameter measured in millimeters (mm). As larger the wheel is, as faster the speeds that a skater can go with, due to a higher momentum. However, larger wheels provide a higher skater positioning that cause reduced stability and, consequently, require more skating skills.
Wheels in the range of 72-mm to 80-mm are perfect for slalom, artistic, and figure skating. Wheels wheels in the range of 80-mm to 90-mm are better for recreational, and fitness skating. Racers, marathoners, and downhill skaters typically use wheels in the range between 90-mm to 125-mm .
Each inline skates frame is designed to accommodate a certain wheel size or range of sizes, and those restrictions should be addressed accurately!
Core: The core consists of a hub and spokes. The inner hub houses two bearings and one spacer, which is where the axle resides. The outer hub and spokes bond to the polyurethane-made tire material itself.
The core design and the material it is made from dramatically effect a wheels features. A wheel undergoes stress from many different directions. Cores range from a solid construction in aggressive wheels to lightly-spoked in racing wheels. The standard hub is called a 608 hub, which is designed to accomodate 608-type bearings.
Profile: The profile is the cross-section of the wheel where it meets the ground, when viewed head on. The profile or curve determines how much of the wheel comes in contact with the surface at any given time.
As the industry standard, all wheels are 24-mm thick, but it's the variation in a wheel's footprint what provides different functionality. The larger the footprint, the better the traction and stability.
Hardness: The durometer reading is a measure of the hardness of the material that makes up the wheel's tire. The higher the number is, the harder the wheel. Harder wheels will last longer, but will less absorb shock and vibration coming off the pavement. Also, they would provide less grip with the surface causing reduced control during sharp turns.
Some skaters use mixed durometers to achieve a better balance of grip, shock absorption, and durability than is possible with a single hardness.
