Wheel hardness is measured in the durometer a scale
May 3rd, 2009
Wheel hardness is measured in the durometer a scale, from 75a to 99a. You may see skateboards marked 100a or higher, but don’t be fooled ” the A scale only goes up to 99. Street skateboard wheels are usually very hard, which allows them to slow down quickly and store energy as you move along. This makes it suitable for tricks and jumps. The same is true with vert wheels, which are mostly used on ramps, uphill, and upward curves. Softer wheels provide better maneuvering and speed control, making them ideal for slalom racing and long boards.
