Why doesn't Tig have the Sons of Anarchy tattoo on his back similar to Jax?

While watching Sons of Anarchy Season 5 Episode 3: "Laying Pipe" I noticed that Tig doesn't have the Sons of Anarchy logo tattooed on his back.

However, I assumed that all members have this tattoo, especially seeing as they went to great lengths to burn it off the back of Kyle Hobart (an excommunicated traitor) early on in the first season episode "Giving Back".

Is there a reason why Tig doesn't have this tattoo?
