It was time for new tires and I went ahead with new wheels as well. I was looking for 18" wheels off a 2006-2007 but couldn't find any. The new wheels are Tundra 18" wheels and the tires are 275/65/18, which makes them 32.1". The old tires are 275/70/16, which makes them 31.2". They fit without any modifications or rubbing. I did use my old center caps as the new ones won't clear the front axel. Caps fit perfectly without any trimming required.
