I've got a 2019 Silverado LTZ running a BDS 4" kit and Nitto 35x12.5x20 on fuel wheels and was concerned about not having a full size diameter spare. Finally talked with my local mechanic and he was able to find me a 35x10.5x17 that would sit the stock spare tire. And low and behold we got it to tuck up into the factory location. Im so excited I had to tell you guys!
