Skateboard Wheels: Size & Hardness

The same board can feel very different with another set of wheels. Match your wheels to the surface and the skating you want to do.

Diameter is measured in millimetres

As broad setup examples, 52–54mm wheels are common on conventional street and park boards; larger wheels are often chosen for cruising or transition. Bigger wheels need more clearance and can change the feel of the board. Do not fit a larger diameter without checking the truck height, turn clearance and any riser requirements.

Hardness needs a little context

A-scale numbers give a rough comparison: lower figures generally mean softer wheels. Soft cruiser wheels, often around 78A–87A, can take the edge off rough ground. Hard street wheels commonly sit in the high 90s and above, while some modern formulas occupy the middle. These are examples rather than fixed boundaries, and different formulas can feel different at similar stated ratings.

Choose for the ground you have

Smooth skatepark concrete and rough local paths ask different things of a wheel. A hard wheel can feel lively at a park and unpleasant on coarse tarmac. A soft wheel can be comfortable for cruising but grip more when you want a controlled slide. No wheel makes loose gravel, wet paving or traffic a suitable beginner practice surface.

Check for wheelbite

Wheelbite happens when the wheel catches the underside of the deck during a turn. Look for rubbing marks, check the clearance and ask a shop to assess the setup if needed. Suitable risers, wheel size and bushings may help, but each change should be considered together. Do not solve it by making the trucks so tight that you cannot steer.

Your next move

Name your usual surface before choosing wheel hardness, then confirm clearance for the diameter.
