The Kelly Safari MT tire has large tread blocks and design specifically for off-road driving, mud, dirt and rocks. It features large inter-locking tread blocks that are optimized to provide maximum traction while off-road as well as highway stability for your average commuting. The large outer tread blocks are made to promote self-cleaning and to eject debris that could encumber the tread and reduce efficiency. The big aggressive lugs look great on Jeeps and 4X4s at a price that is a lot less than most other mud terrain tires.
