So the project desert sled is comming along...slowly! But I have a question for you guys who also ride the street. Im looking at a few tyres for the beast but want DOT approved knobbies so they will last on the street. Are the MT21s better that the Karoo IIs? I hear great things about the Karoo IIs but have not ridden on the but remember the MT21 was great but more knobbie feeling on the road but I dont really mind that either! Whats the deal and what do you guys use...thanks!
