Surprisingly, this greasy SA told me I should do it before it expired.
Personally, I don't care if a rear RFT is now $433 ea. If I got a flat, I'd use it. If not, let it expire.
I paid $390 for my tire protection back in 12/06, and I never got a flat, so I never used it. I'm not going to commit fraud over $390. It has to be at least $400 or $425.
