The highly anticipated Subrosa Street Digger tire is in stock and shipping to stores now! Following the success of the Grave Digger tire, and how well it works, we realized the need for a less aggressive more street version of the tire. So we went in, lowered the height of the knobs, reduced the space between them, and lengthened the knobs on the sides, for more sidewall protection. So dialed, so grippy, and now in black, or tan walls. The perfect compliment to a Grave Digger front tire is a Street Digger in the rear.
