PROLINE SLIDE LOCK S3 PRE-MOUNT VEL. V2 WHITE WHEELS (2)This is a pair of pre mounted Slide Lock 1: 8 Buggy Tires. The Slide Lock is a unique tire design from Pro Line that is made specifically for smooth, low grip tracks. The Slide Lock features a pattern of small, tightly packed hexagon and triangle shaped pins so you can lay down as much rubber as possible. The tread on the new Slide Lock is laid out wider across the tire carcass for a flatter profile overall compared to other Pro Line 1: 8 Race Tires.
