Like the title says. I have 4 Cragar D Window 15x8, 4" back spacing. These tires have been used for rock crawling. And do have rock rash. All hold air. 1 tire has the inside lip bent out (like a bubble in a tire). I have never used Fix-a-Flat or Slim. I would like to sell as a set. I will post pics Tuesday night when I get back to San Diego.
