The uv map isn't right on the object with that texture, right click the object go, to texture, go to edit uv and move the green lines around that's till the textures are how you want them, some textures aren't right for this though and some will look stretched and just bad so you may have to use different ones or use an editing program like gimp or photoshop to position them right.
