It all depends on what gen is your Tundra and how much lift you’re giving your vehicle with a leveling kit. On a first-gen Tundra, you can go up to 17-inch rims with a bigger width than factory tires if you get a 3-inch kit. Then, on a second-gen Tundra, you will have the option to add 20-inch rims with a much wider size if you go with a 3-inch kit.
