Q: What does (MM) mean on skate wheels, and why do wheels with the same size and hardness perform differently?
A: Wheel diameter is measured in millimetres (MM), indicating size. Bigger wheels roll faster and smooth over rough surfaces; smaller ones give better control for tricks.
Wheels with same MM and A differ due to material, shape, core design, surface texture, and manufacturing precision, impacting grip, speed, and feel.
Q: What does (A) mean on skate wheels?
A: (A) shows hardness - softer (lower numbers) grips better for outdoor smoothness; harder (higher) rolls faster indoors and lasts longer. MM and A together match wheels to your style: speed, control, or smoothness.
Q: What skate wheel size is best for different age groups?
A: Below 12 years: 90mm wheels – easier to control and more stable while learning.
Ages 12-15: 100mm wheels – balanced speed and manoeuvrability for growing skills.
Above 15 years: 110mm wheels – maximum speed and smoother rides for experienced skaters.
Q: Can I use the same inline wheels for both road and rink skating, or do I need different wheels for each surface?
A: No, you don’t need separate inline wheels for rink and road the same wheels work fine on both surfaces for everyday skating. Most serious skaters keep a dedicated competition set for each road and rink surface separate because regular mixed use wears them down, reducing that ultimate grip and push needed to win medals.
