1994 silverado 1500 4x4....can't afford a lift and couldn't figure out the wheel/tire chart cuz I'm an idiot or something lol anyways...the leveling kit by readylift says 33" tires will work....is that possible? after reading about gearing changes for bigger tires I'm not sure about any bigger than that anyways because 4:56 gears in a daily driver chevrolet silverado sounds bad...I need alittle MPG
