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: For ages 8 and under, use 62mm or smaller for control and stability in beginners.
For ages 8+, larger than 62mm suits smoother rides and speed as skills grow.
Q: Can I use quad rink wheels on the road?
A: Quad rink wheels (harder) suit smooth indoors but fail outdoors: rough ride, poor control, fast wear, flat spots, cracking, and grip loss. Use softer, wider outdoor wheels for grip, shock absorption, and safety on roads.
Q: Can I use quad road wheels on the rink?
A: Road wheels (soft/grippy) work outdoors but indoors create excess grip, slowing speed and turns. They won’t damage, but switch to harder rink wheels for faster glide and control indoors.
