I hope you mean speed, if not I'm at a loss for words. Friction effects both the contact between the wheels and the ground, as well as your shoe and the grip tape. You would like a high coefficient of static friction between the ground and your wheels so you don't end up skidding, fishtailing, and later flat-out falling down. Also, you would want a medium-level coefficient of kinetic friction and possible a medium-high coefficient of static friction between the grip tape and your shoe in order to grip the board, yet still be able to slide your foot for flip tricks. If the coefficient of static friction between the grip tape and your board is too high, it won't flip properly as it might overflip or flip on an unusual axis if it were to be too low. As you use the grip tape, both coefficients will decrease because the grains on the grip tape will be smaller and easier to pass over with a lesser repelling force of friction.
Coming from a skateboarder in college-level physics.
The friction between the foot and the ground creates a force that opposes the motion of the skateboard, causing it to slow down. This friction converts the kinetic energy of the skateboard into thermal energy.
For a skateboard, friction works between the wheels of the board and the axis, as well as between the wheels of the board and the ground when the board is in motion. Since friction works in a direction opposing motion, it is only in effect when the when the board or the wheels of the board are in motion.
The main forces acting on a moving skateboard are friction with the ground, air resistance, and the force applied by the skater to propel the skateboard forward. Additionally, there may be gravitational forces affecting the vertical motion of the skateboard.
A skateboard can be stopped on a flat surface by using your foot to drag and slow down, or by using the skateboard's tail to perform a manual stop. Additionally, you can also use friction from the ground by letting the wheels come to a gradual stop.
The force of a skateboard rolling down the sidewalk is primarily due to the push-off force provided by the skater's foot. Additionally, factors such as gravity, friction between the wheels and the sidewalk, and air resistance also contribute to the overall force propelling the skateboard forward.

friction
the friction between the wheels and the surface of the ground affect the speed of the skateboard. fo instance if you ride the skateboard on a smooth surface (with less friction) the skateboard will go faster.

Using a lubricant on a skateboard can significantly reduce friction between the wheels and the bearings, allowing for smoother and faster rides. This decrease in friction can lead to increased speed, as the skateboard rolls more freely with less resistance. However, excessive lubrication might attract dirt and debris, which could negatively impact performance over time. Proper application and maintenance of lubricants are essential for optimal results.

Inertia
Friction that effects the object in motion. insignificant friction is friction that is so small it is negligible.
