What Size Skateboard Wheels Do You Need?


If you’re building a skateboard for the first time or as a gift, it can be daunting. But if you’re up to the wheels that means you have already chosen a deck and trucks. Those items will help determine what size skateboard wheels work with your skateboard. 


Skateboard wheels vary in color, size and durability. Skateboard wheels are most commonly made of polyurethane. The diameter (width) and durometer (hardness) of the wheel affect the way the board rides. The diameter and durometer are a matter of personal preference and skating style. 


Diameter – All Skateboard wheels are measured in millimeters (mm). The smaller the number, the smaller the wheel. Smaller wheels are slower; bigger wheels are faster.  


50-53mm – Small slower wheels, stable for trick riding and smaller riders skating street, skate parks and bowls. 


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.

What size skateboard wheel do I need


What durometer skateboard wheels do I need? 

Durometer measures the wheel’s hardness. Harder wheels are faster; softer wheels are slower but have better grip. 


Skateboard 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.
