Are you tired of burning down brand-new Positrons into ghost pins or slicks in order to be competitive at your track? Pro-Line has the solution for you! Introducing the Shadow 2.2" Buggy Rear Tire, which has the same Positron tire shape but requires much less grinding and burning in to get into the sweet spot. The tread of the Shadow matches the internal webbing exactly as if the internal webbing grew from the inside out. This provides consistent stability when running as ghost shadow tread while the short tread makes it easy to burn off when needing a full slick.
