A few more info about rollerblading wheels.
Core - consists of the hub and spokes. The inner hub houses the bearings and spacer, which is where the axle resides. The outer hub and spokes bond to the tire material itself, which is the polyurethane.
The core design and material gives the wheel the stability. Aggressive wheels have cores with a solid construction.
Profile - it’s is the cross-section of the wheel where it meets the ground, when viewed head on. The profile determines how much of the wheel is in contact with the surface.
Choosing the wheels.
Once you’ve learned about the properties, you can choose the wheels based on that knowledge. You r wheels have to have the right hardness and diameter for your weight, ability, style, and speed.
If you’re a recreational skater, the hardness of your wheels should be between 78A to 82A. You can also use mixed durometers to achieve a better balance of grip, shock absorption, and durability than is possible with a single hardness.
Wheels the most appropriate for ladies are the ones with 72-mm wheels. Heavier, male skates should choose skates with 80-mm wheels. Mid-weight skaters, males or females, should choose 76-mm wheels.
Summarizing, hardness and size are the most important while replacing the wheels. You might want to check your skates if you have a visible wear pattern on the front or rear wheels. If so, you may want to refit your skates with harder wheels in these positions.
