Skate Wheel Hardness Guide

Which wheel hardness do you need? Outside on asphalt, go soft: 78A to 85A. On a smooth rink floor, go hard: 95A and up. Hardness is printed on the wheel as a number followed by an A; the higher the number, the harder the wheel.

Why hardness matters

A rink floor is already smooth, so a hard wheel rolls faster there. Asphalt has grain, and a hard wheel sends every bit of it up into your feet; a soft wheel gives a little and absorbs it. That is why the same skates feel like different skates after a wheel change.

Size: bigger rolls over more

For quads, outdoor wheels are usually around 62 mm, rink wheels around 57 to 58 mm, and park wheels smaller. For inline, fitness and urban skates use 76 to 90 mm, distance skates 100 to 125 mm, and aggressive skates 55 to 72 mm. Your frame or plate limits the size you can fit: check your skate before buying.

FAQ

What hardness are outdoor roller skate wheels?

78A to 85A. Riedell gives the same range for outdoor wheels.

What hardness for an indoor rink?

95A and up. Riedell's range for indoor wheels starts lower, at 88A, and goes to 101A.

Does my weight change the hardness?

A little: heavier skaters can use harder wheels, lighter skaters softer ones, within the range for the surface. The surface comes first.

Can I use outdoor wheels indoors?

You can, but outdoor wheels feel slow on a rink, and indoor wheels lack grip outside.

Where does the data come from?

From an experienced skater's own ranges, checked against wheel guides published by Riedell, Moxi and Powerslide, and retailer guides. Sources and dates are shown in each result.
