I am wanting to know from those who run 275/65/18 tires if I can run with these on the street with no rod mods? I want to be able to run without rod mods for everyday driving but just change for offroad. Also curious if anyone does have the rod mods what the dealer says about them? Tires in the running-Dunlop Maxx traction 275-65-18 or no rod mods the Cooper LTZ 285/60/18(found for about $630)
