My cruiser came with 1.175 tires but I liked white walls, so I put those on and sold the originals. The bike is all black and the white walls were too contrasty, so I sold them just a couple of weeks after fitting them. Another thing was, I put the bike maker's fenders on it, and they are 3 1/4" wide but the original tires looked too skinny. So I sold those and got 2.125. Now I'm happy at great expense. Aesthetics plays a role in my tire choices, and I like the fat look.
