Atturo® Tire releases the fourth tire in its Trail Blade® series with the most intimidating tire design to date – the Trail Blade BOSS®. The tread is designed from the Quartermaster QSA-1 BOSS HOG knife, a blade made for heavy duty, hard core use. Alternating shoulder blocks follow the outline of the knife handle tread. The tread’s high void ratio provides superior grip across the varied terrain. Smaller center tread blocks are linked for stability from the high abrasion abuse of rocks.
