Subrosa set off to create a long lasting tire design that can handle today’s current riding trends and tricks and came back with two unique designs, the Grave Digger and the Street Digger. Click HERE to view more specs, more photos, and to purchase your own set. The Grave Digger tire is a great tire for the rider who rides dirt and occasional street/park or any rider who wants a depper tread. The Subrosa Street Digger tire features a more low profile tread for the streets and park riding. Both designs function great, and with the colored speedwall versions there’s a unique tire for every rider!
