Roller Skate Wheels Guide: Indoor vs. Outdoor, Hardness and Size
Choose roller skate wheels by surface. Outdoor wheels are soft, about 78A to 82A, to absorb cracks and grip rough pavement. Indoor rink wheels are harder, usually over 90A, for a smooth, fast roll. Hybrid wheels around 85A handle both. Most indoor wheels are 59–62mm tall, and outdoor wheels run about 60–70mm.

What roller skate wheels do I need?
Match your wheels to where you skate most. Softer wheels grip and cushion; harder wheels roll faster and slide more easily on smooth floors.
| Where you skate | Hardness | Typical height | Why |
|---|---|---|---|
| Outdoor: sidewalks, trails, boardwalks | 78A–82A | 60–70mm | Soft urethane absorbs bumps and rolls over cracks instead of bouncing |
| Indoor and outdoor (hybrid) | About 85A | Varies | A middle ground; common on kids’ and beginner skates |
| Indoor rink: coated wood or traditional rink floor | 94A–100A | 59–62mm | The floor supplies the grip, so hard wheels won’t stick |
| Slick indoor: polished concrete or polished wood | 84A–90A | 59–62mm | Softer wheels add the grip a slick floor lacks |
| Sport courts | 88A–96A | 59–62mm | Balanced grip and slide |
| Skatepark ramps and bowls | 92A–97A | 55–59mm, narrow (about 34mm) | Hard and narrow for smooth concrete |

What is the difference between indoor and outdoor roller skate wheels?
Indoor wheels are harder and outdoor wheels are softer. Roller Skate Nation says most skaters use 78A–82A wheels outdoors and wheels over 90A indoors. A soft wheel absorbs shock and has more rebound, so it rolls over textured or uneven ground. A hard wheel has less grip and a less “sticky” roll on smooth surfaces such as rinks, ramps and smooth concrete.
| Indoor wheels | Outdoor wheels | |
|---|---|---|
| Hardness | Harder, usually over 90A | Softer, about 78A–82A |
| Feel | Fast, slidey, responsive | Cushioned, grippy, smooth over cracks |
| Height | Usually 59mm or 62mm | Often taller, up to about 70mm |
| Outdoors? | Rattly and slippery on rough pavement | Built for it |
| Indoors? | Built for it | Can feel sticky and slow on a rink floor |
Can you use outdoor wheels indoors? You can, but they’ll feel slower and grippier than rink wheels. Indoor wheels outdoors will feel rough and slide out more easily on uneven ground. If you skate both, choose hybrids around 85A or keep a second set of wheels.
What does roller skate wheel hardness (durometer) mean?
Wheel hardness is measured on the durometer A scale, shown as a number followed by “A.” Lower numbers are softer and grippier; higher numbers are harder and slide more. Roller skate wheels generally run from 78A to 100A, according to Derby Warehouse. Some brands use names such as “hybrid” or “firm” instead of a number.
| Durometer | Feel | Best for |
|---|---|---|
| 78A–82A | Soft, most grip | Outdoor skating |
| 84A–90A | Medium-soft | Hybrid use; slick indoor floors |
| 88A–96A | Medium-hard | Sport courts and moderate indoor floors |
| 94A–100A | Hard, least grip | Rinks with grippy coated floors; dance and jam |
Body weight matters too. Derby Warehouse notes that heavier skaters get more grip from their weight and can go slightly harder, while lighter skaters may want slightly softer wheels.
What size roller skate wheels should I get?
Quad roller skate wheels range from about 47mm to 70mm tall and 27mm to 42mm wide (Roller Skate Nation). Sizes are listed as height × width, so “62x38mm” means 62mm tall and 38mm wide.
| Height | Typical use |
|---|---|
| 47–55mm | Very hard wheels for sliding and shuffle skating |
| 57mm | Artistic and freestyle skating (most maneuverable) |
| 59–62mm | Indoor rink, speed, derby and dance skating |
| 60–70mm | Outdoor skating and cruising |
- Height: Smaller wheels accelerate faster and keep your center of gravity low. Taller wheels take less effort to hold speed.
- Width: Narrow wheels, about 38mm and slimmer, are more agile. Wide wheels, about 40–44mm, are more stable.
- Fit: Make sure a new wheel size fits your plate before you buy.
Do roller skate wheels come with bearings?
No. Roller Skate Nation notes that bearings don’t come with new wheels, so you’ll move your bearings over or buy a new set. Your axle size, not your wheels, sets the bearing size. Most current skates use 8mm axles (608 bearings), while some high-end plates use 7mm axles (627 bearings). To check, read the stamp on the bearing shield or check the nut size: 5/16 inch means 8mm and 9/32 inch means 7mm. Or try sliding the bearing over a No. 2 pencil: it slides on if it’s 8mm and won’t fit if it’s 7mm.
Soft wheels below 84A need a hub to hold the bearing seat securely. See the skate bearings guide for ABEC ratings and cleaning.
How do you change and rotate roller skate wheels?
- Loosen each axle nut counterclockwise with a skate tool and slide the wheel off the axle.
- Press your bearings out of the old wheels and into the new ones, unless the new wheels came with bearings installed.
- Slide the new wheel on and tighten the nut clockwise until the wheel spins freely without side-to-side wobble. If it doesn’t spin freely, back the nut off.
- Replace locknuts that have been used more than twice. Worn nylon can let a nut back off.
Rotate your wheels when one edge, usually the inside edge, wears faster than the other, or when some wheels look smaller than others. Rotating regularly makes wheels last longer. Freshly rotated wheels can feel strange for a few sessions.
What are the best outdoor roller skate wheels for beginners?
For outdoor skating, look for soft wheels around 78A to 82A, about 60–70mm tall, with a hub if the wheel is softer than 84A. If you’ll split time between a rink and the sidewalk, an 85A hybrid is the simplest choice. The Roces RC1 complete skate ($100.00), for example, comes with 54x32mm 85A wheels.

Frequently Asked Questions
What is the difference between indoor and outdoor roller skate wheels?
Indoor wheels are harder, usually over 90A, for a fast roll on smooth rink floors. Outdoor wheels are softer, about 78A to 82A, to absorb bumps and grip rough pavement. Hybrid wheels around 85A work for both.
What durometer is best for outdoor roller skate wheels?
Most outdoor roller skate wheels are 78A to 82A. Derby Warehouse says outdoor wheels are almost always 78A. Softer wheels absorb cracks and pebbles and give more grip.
Can you use indoor roller skate wheels outside?
You can, but hard indoor wheels feel rough and slippery on uneven pavement. Use soft outdoor wheels around 78A to 82A outside, or 85A hybrids if you skate both indoors and out.
What size roller skate wheels should I get?
Most indoor wheels are 59mm or 62mm tall, outdoor wheels are often 60mm to 70mm, and artistic skaters often use 57mm. Smaller wheels are more agile; taller wheels hold speed with less effort.
Are harder roller skate wheels faster?
On smooth floors, harder wheels roll with less grip and feel faster and slidier. On rough pavement, softer wheels usually feel faster because they roll over bumps instead of bouncing over them.
Do roller skate wheels come with bearings?
Usually not. New wheels are typically sold without bearings, so you move your bearings to the new wheels or buy a new set. Check the bearing size first: 608 bearings fit 8mm axles and 627 bearings fit 7mm axles.
How often should you rotate roller skate wheels?
Rotate them as soon as one edge, usually the inside edge, wears faster than the other, or some wheels look smaller than the rest. Regular rotation makes wheels wear evenly and last longer.
