This 6-ply rated radial tire’s compound was reformulated with more natural rubber for its elastic properties. Traction spikes were added for ultimate grip and durability in a wide range of terrain: light mud, dirt, gravel, and hardpack. Each lug is dimpled with more biting edges for better traction and stability. A surprisingly aggressive tread pattern means the Dirt Devil offers a great experience no matter what type of landscape you’re looking to dominate.A/T tire has a tread depth of .625" and the X/T model tread depth is 1.21"
