Skateboard wheels are designed in many different sizes and hardness. Skateboard wheels are made of a rubber-like material called urethane. The size and hardness of the wheels affect the smoothness of the ride on a skateboard, how well it handles, and its speed. Skateboard wheels are normally 52 mm to 60 mm and have their own ball bearings built in. Street skateboard wheels are usually very hard, which allows them to slow down quickly and store energy as you move along. Park wheels are usually made of a softer urethane for better bite and handling. Modern skateboard wheels are bidirectional, meaning that they can be attached in either direction unlike the wheels on a car or the back wheel of a bicycle. This means that if the edges start to wear, you can flip the wheels and use them on the other side. Skateboard wheels are attached to the trucks by hex head axle bolts and ABEC (or another company's) ball bearings to provide the free-spinning movement of the wheels.



are axles fastened to a baseplate and are made of an aluminum alloy moreover they are extremely sturdy. Trucks come in a lot of different shapes, sizes and colors. These trucks are made from special cast metal and let the skater to rotate the board. Accordingly how firmly the nut on the kingpin is held, the trucks can be slack or rigid identical to the suspension of a car. The key reason behind trucks that are not rigid is to allow you to rotate or flip without lifting your front wheels off the floor. The free your trucks are, the more you will be able to tilt in one way or the other way.

Skateboard wheels do not merely retain your skateboard rolling but are dependable for keeping you on your feet as well, while you engage different terrain. Wheels are fixed to the axles of the trucks by way of a hex bolt moreover there are 8 bearings, two fit into each wheel with a spacer among these bearings.

The skateboard wheels come in different sizes, from 48 to 100 mm, and different hardness. Most skateboard wheels, like mentioned above, are made from urethane, and have a hardness rating stamped on the wheel for example, 95a or 100a always with an "a" after the number. The higher is the number the harder the wheel. For example, a 101a wheel is harder than a 95a. So a good choice for street riding might be a 100a or 101a. A 95a would do well on ramps and in a skateboard park.

So, a skateboard is made up of three main parts, the deck, the trucks like , and the wheels. The deck is the flat part on top where you plant your feet. The trucks are bolted to the bottom of the deck. This is your suspension and axles for the deck and wheels. The wheels bolt onto the ends of the trucks and include wheel bearings so the wheels can spin. Wheels come in different sizes and hardnesses to help you custom tailor your ride.
