Dunlop designed the D606 tire to be street-legal but with an emphasis on aggressive off-road riding and great durability. A full-depth tread pattern designed for rigorous off-road use yields excellent traction on everything from hard-packed fire roads to soft single-track trails. At the same time, the D606's tread compound is engineered for good highway durability and grip.
The Dunlop D606 is R rated (max speed of 106 mph)
