I am placing an order tomorrow for a new rear tire/tubes for my moped. I was given one thats almost new for the front so I only need to purchase the back. The front one that I was given is for street only(which is the only place I ride it anyway). The rear one I want to order is a "Dual Sport" for street and trails. Its significantly cheaper than buying an all street one. Is that ok or do I need to have the same types of tires(street only) on the front and back? If it wont make a difference, great. if its a small difference, no worries. If I am going to screw something up-never mind.
