What is traction?
Traction in snowmobiling is the reduction of track slippage. As the engine transfers power to the track, the track digs into the surface to push the sled forward. If the track slips, some of the engine's power is lost. Studs bite into the surface to keep the track from slipping, and prevent lost engine power. Lost engine power is poor fuel economy. Track slippage also occurs during breaking; Better traction means better braking.

General Studding Patterns
Studs placed where pressure (and weight) is concentrated work better. Pressure is concentrated near the outside edge of the track on turns and on the center of the track when going straight. Studs, to improve turning, should be placed on the outside edge of the track; acceleration studs on the center. Studs benefit from any additional support available. Place studs within the cleat and over the belt on a cleated track. Place studs against the cross ribs on a rubber track.
