Kumho RA12 Overview

The mixed service Kumho RA12 tires provide excellent highway performance and superb off-road flotation. They feature an optimized rib and groove pattern that provides excellent grip on and off-road surfaces. In wet conditions, the wide grooves channel water from the tread contact area to reduce the risk of hydroplaning. The tread pattern is optimized to minimize wear and deliver excellent ride stability. These tires are also engineered to enhance fuel efficiency.

Features & Benefits

  • Closed shoulder design for superior handling
  • Cut and chip resistant tread compound for durability
  • Wide surface contact area for enhanced off-road flotation
