I have a 1987 Ford Ranger 4X4 with a 6" lift and I am looking to buy a set of mud tires. Right now I have a set of Dunlop Mud Rovers and they just arent working out. I want something that is really loud on the highway, such as Nitto Mud Grapplers, Thornbirds, Pitbull Rockers, or something of that nature. I have a 6" susp. lift and a set of 15X10 wheels. I want to get some 35x12.50x15 or 35x13.00x15. Again, I need something that is loud and sounds like a fire truck coming down the road. Other suggestions are welcome, I just need some help and I know they are all nice, loud tires. Any info would help a lot. Thanks
