I need a little help from everyone. I currently have a 2014 Silverado LT 4x4 crew cab. It has a 2.5in leveling kit in the front and 1in block in the back. I’m running 285 65 18 Discover SST Maxx tires. I would really like to run 285 75 18 Nitto Trail Grapplers. Is it possible to put these on with out it rubbing. The overall diameter of these tires are 35in. If they do rub how do I know where to trim and how or would spacers help? Thank you all for your help and advice
