It is extremely important to choose the correct wheels when assembling your board. Longboard wheels tend to be larger than standard skateboard wheels, and usually ride better on rougher surfaces. This allows riders to reach a higher top speed compared to riding smaller wheels. The durometer for longboard wheels usually range from 75a to 90a.
Longboard wheels vary in color, size and durability. Longboard wheels are most commonly made of polyurethane. The diameter and durometer of the wheel affect the way the longboard rides. The diameter and durometer are a matter of personal preference and skating style.
Diameter - All longboard wheels are measured in millimeters (mm). The smaller the number, the smaller the wheel. Smaller wheels are slower; bigger wheels are faster.
| 54-59mm | Average wheel size for beginners and bigger riders skating street, skate parks, bowls and vert ramps. |
| 60mm + | Specialty riders skating longboards, old-school boards, downhill and dirt boards; made for speed and rougher surfaces. |
Durometer measures the wheel’s hardness. Harder wheels are faster; softer wheels are slower but have better grip.
Longboard wheel durometer is usually measured on a Durometer A Scale which goes from 1-100 to measure hardness. Some companies use the B Scale which measures 20 points lower, allowing the scale to be extended by 20 points for harder wheels. So an 80b durometer is the same as 100a durometer. These skateboard wheels have a larger and more accurate range of hardness. The average wheel durometer is 99a.
| 78a-87a | Soft wheel good for rough surfaces, longboards or street boards that need lots of grip and easier to roll over cracks and pebbles. Designed for a smooth ride cruising, longboards, hills and rough surfaces. |
| 88a-95a | Slightly harder and faster with a little less grip, but the grip's still good. Street; rough surfaces. |
| 96a-99a | Good speed and grip - an all-around wheel. Great for beginners skating street, skate parks, ramps and pools. Smooth surfaces. |
| 101a + | Hardest and fastest wheel with the least grip. Ineffective on slick and rough surfaces. These are pro wheels. |
| 83b-84b | Wheels using the B scale are extremely hard, measuring 20 points lower than the the A Scale in order to allow the scale to extend another 20 points for harder wheels. |
Longboard skateboard wheels also come in many different shapes to suit various riding styles. Wheels with rounded lips are better for cruising, freeriding and sliding, rather than downhill racing. Having a rounded lip allows the wheel to enter into slides with ease. Having the rounded lip when racing may create issues, because the edges will not grip the street when turning. Wheels that have straight edges rather than a round edge are typically designed to give riders more grip and control. Straight edge wheels work great for downhill racers that need to grip the street.
Wheel bite occurs when your deck and wheels rub together. It usually occurs when you are turning hard or when you land a trick, in which you stop immediately upon impact. Where your deck meets your wheels you are usually left with an indent. To reduce this from happening you should look into assembling your board with riser pads or medium to hi skateboard trucks.
