I have a 2007 crew cab SE. I have recently bought a Rough Country Leveling Kit with the optional 1" block for the rear. My truck is two wheel drive , I am just looking to raise the height and add some new wheels. I'm currently in Afganistan and hoping to order the wheels and tires before I get home. I have 18' factory rims and I am looking to go down to a 16". The ones that I have picked out are the DC-1 Black 16x8 6 on 5.5 with a backspacing of 4.03 and offset of 12mm. Will this work or do I need a large size. Any information would be helpful
