This can be a tough question at first because of the large variety available. Let's briefly talk about the thermology to get a better understanding of how to choose the right wheels for each discipline.
Durometer (a). Specifies the hardness of a wheel. A typical hard skateboard wheel is 100a and a typical soft longboard wheel is 78a. Softer wheels are more comfortable and are better for controlling your speed when sliding. Harder wheels are more forgiving when landing tricks and will be faster on smooth surfaces.
Diameter (mm). Specifies the size in millimeters. = A typical skateboard wheel is between 52-58mm. a typical longboard wheel is 65-76mm. It is crucial not to take unnecessarily big wheels for your riding style for the sake of saving weight.
Contact patch (cp). Specifies the width in millimeters. It can be seen as the surface which makes contact to the ground. Wider wheels are more grippy on a dry surface. Smaller wheels are lighter in weight and are easier to slide.
Core types:
- Hub: Hard plastic ring, just enough to connect the urethane and hold the bearings in place. It's the most common type of core.
- Closed-core: Hard plastic part between the bearings and the urethane. Saves weight in comparison to a hub core wheel and reduces friction during slides.
- Open-core: Hard plastic spokes between the bearings and the urethane to save even more weight in comparison to a closed core. Most common with the bigger 75mm+ wheels.
Edge types:
- Round lip: best for sliding
- Square lip: best for grip in fast corners.
- Beveled edge: a diagonal edge to decreases the contact patch. this makes it easier to slide compared to a square-lipped wheel.
Core positions:
- Centerset: the core is exactly in the middle. It allows for the wheels to be flipped. This is the most common type of skateboard wheel.
- Sideset: the core is at the far inner side of the wheel.
- Offset: a defined offset between center-set and side-set. This is the most common type of longboard wheel.
