They are Hostile ATX in that picture. You can pick up cheap mad Max clones of them now but they aren't very good. I tried them on my DBXL (the ATX, not the clones) and are probably only any use if you drive a mix of tarmac and gravel. They are terrible on grass and the grip roll is atrocious. On wet grass you may as well use slicks. Those big knobbly tyres by surface area don't offer any more grip, often less except in the direction you don't want to be going in.
