Well,even though like Linc said,you can run badlands and those types of tires on road,but it WILL speed up your tire wear. So make sure to get tires for specific surfaces. One of the most dramatic examples of this is on my Baja (totally different but its the same principle) I use hostile extra hard MX's,I ran them off road strictly for over a year with over half the tread still left. I took it on the street for $h!ts and giggles and DESTROYED them in a few hours. So know where to run your tires and change out your center diff fluid.
