Skateboarders may give little thought to their board’s wheels when they first start to ride. Yet as they gain confidence and learn to handle the board well, they quickly realize how the wheels affect virtually everything!

A skateboard’s wheels impact everything from how you feel on a skateboard and how fast you’re able to go to how you can control the board’s movements. Once you’ve been riding for a while, you’ll want to reconsider the type of wheels you’re using so they suit the type of riding you prefer.

There are two things to consider when evaluating your skateboard’s wheels: the durometer of the wheel or its hardness, and the diameter or size of your wheels. Durometer measures how resistant wheels are to penetration, and ratings typically fall in the 75A to 90A range, with A referring to the type of material used to make them.

The higher a wheel’s durometer rating, the harder the skateboard wheels. Those who are into vert or street skating usually prefer harder wheels, as they are smooth but tend to have a good grip. A durometer rating of 97A or higher is a good choice for vert surfaces or those who are into technical street style skating.

Skaters who are just into cruising or long boarding usually choose a softer wheel. Softer wheels aren’t as fast as harder wheels, but they make it easier and more comfortable to ride on bumpy surfaces. 78A is a fairly standard wheel for cruising, although anything in the range of 75A to 85A may be suitable.

If you enjoy different types of skateboarding or want a more flexible wheel, medium hard wheels in the 90A to 97A range may be a good compromise. As you experiment with different wheel durometers, you’ll find which type of wheels ideally suits your skating style and preferences.
