I recently bought some 24x12 Fuel FF29 Rims with Like new 325/45/24. I have a 2015 SIlverado LT 2wd, Whats the best way to mount these rims at lowest cost to me? Could I do a 5 inch block in rear with new shocks, 4.5 spindles and 3 inch leveling kit in the front? Will the size of tires hurt the truck besides gas mileage? Need some answers, thank you in advance this is my truck and rims and the picture by custom offsets is the "look" im going for!!
