The type and size of skate trucks you choose directly affect your stability, and what tricks you can and can't do on your skateboard. Choosing and maintaining the right skateboard trucks is also key to avoiding wheel bite, which happens when your wheels rub against your board and cause you to stop on impact during a trick or turn. Trucks can easily be adjusted to perform tighter turns or tricks on your board. You can also choose softer bushings for easy turning, or hard bushings for stiff turning. How loose or tight you keep your trucks really depends on what you skate.
