I just pick them up with the tip of an xacto knife blade and line them up, then press the opposite end of where the blade is and press the decal onto the tire and go around it, it should fall right into place and retain its shape. Most of the decals I have are for tires that have some kind of raised area that you can use as a guide for the decal.
Not a problem! You were one of the first people to order from me, so I'm more than happy to have your builds posted up. If you want me to add anything more to the descriptions of your pics, Id be glad to.
