I have an 07.5 that I tow with all the time it currently has a 2" level and 285/75/17 TOYO's. I tow for work and have a 33 ft camper I pull on weekends, my wife has a serious hip injury and I need to get the truck lower for her. I am thinking about taking the spacers out of the coils and installing 2" lowering shackles on rear the running 305/65/17 tires, probably Mickey Thompson ATZ's. Has anyone ran these tires, what are you're thoughts on them, how do thay wear,handle,and tow
