Been shopping around for some wheels and tires for the Spring for my 2020 2500HD Silverado. Thinking about getting a set of fuel wheels that are 20x10 with a -18 offset. I've never purchased aftermarket wheels or tires before and want to get this right so forgive me for being uninformed. I also want to get 35x12.50R20s mud tires to go along with them. What I'm wondering is if I will have to get a lift for the truck or any wheel spacers for this setup at all? Again sorry for my ignorance just want to get this right before I pull the trigger.
