The Kenda Executioner K538 is designed for riders who like to play in the mud! To meet the demands of the muddiest 4x4 riding, the Executioner features big, deep traction bars. The traction bars are reinforced to reduce rollover even when aired down. This also improves ride comfort and increases tread life. The tires are 6-ply rated with an extra tough casing to resist punctures.
