In this guide
Wheels change how a longboard rides more than almost any other part. Two numbers describe most of what you need to know: size in millimetres, and hardness, called durometer, written with an “a” such as 78a.
Wheel size (diameter)
- Larger wheels (about 70mm and up) roll over cracks and rough pavement more easily and hold their speed once you are moving. They are heavier and can take a little more effort to accelerate.
- Smaller wheels (about 60 to 65mm) accelerate quickly, sit lower and feel more nimble. They are less comfortable on rough surfaces.
Durometer (hardness)
Durometer is measured on the “a” scale. A lower number means a softer wheel.
- Softer (about 74a to 80a): more grip, a smoother ride over rough surfaces and less vibration. They can feel slightly slower on very smooth ground.
- Medium (about 80a to 85a): a balance of grip and speed, popular for general riding.
- Harder (about 85a and up): faster on smooth surfaces and easier to slide, but they transmit more vibration and grip less.
Hardness numbers are not perfectly standard from brand to brand, and different wheel formulas feel different at the same number, so treat them as a guide and read the manufacturer’s description.
Choosing wheels by use
| Use | Typical size | Typical hardness | Why |
|---|---|---|---|
| Cruising and commuting on rough roads | About 70 to 75mm | About 75a to 80a | Large and soft rolls over cracks and absorbs vibration |
| Cruising on smooth paths | About 65 to 70mm | About 78a to 83a | Comfortable, with good grip and speed |
| Carving | About 65 to 70mm | About 78a to 82a | Grippy and predictable in turns |
| Dancing | About 65 to 70mm | About 78a to 83a | Stable, low and easy to control at walking speed |
| Freeride (advanced) | About 70mm | About 80a to 86a | Firmer so the wheels can slide in a controlled way |
Wheel shape and contact patch
Two wheels of the same size and hardness can still ride differently. A wide contact patch (the part that touches the ground) gives more grip. A narrow one rolls more easily and slides more readily. Rounded edges are more forgiving when you lean, while square edges grip harder. Manufacturers usually describe these on the product page.
Wheel bite
Wheel bite is when a wheel touches the underside of the deck when you lean hard. It can stop the wheel suddenly and throw you off. It is more likely with large wheels, loosely set trucks and low decks. Risers (small spacers between deck and trucks) or wheel wells can add clearance. Check clearance before you fit bigger wheels.
Replacing wheels
Replace wheels when they are worn flat, have flat spots or are badly chipped. Most longboard wheels are replaced in sets of four and need bearings fitted. You can move your bearings across from your old wheels. See how to clean longboard bearings.

Wheel questions
What wheels are best for cruising?
Larger, softer wheels, roughly 65 to 75mm and 78a to 82a, give a comfortable ride and roll over cracks and rough pavement more easily.
Are harder wheels faster?
On very smooth surfaces they can be, because they deform less. On rough surfaces a softer wheel often feels faster because it does not lose speed to vibration.
What is a good first set of wheels?
Wheels around 65 to 70mm and around 78a are a forgiving starting point, and many complete boards ship with something close to this.
