steelX - thanks for the reply. What happened to the little diagram you posted? It be gone. Being a cheap bastard and already spending way too much on the Toyo's, I plan on getting a 5th and displaying it proudly on my future Shrock rear bumper. I want to get as much life out of these skins as possible. I have no plans on returning the new skins, so that should not be an issue. Thanks again for posting. Would you mind emailing me that little diagram? Also-where would the 5th tire go in the rotation sequence. Cheers.
