That's what's happening currently - The spare that's on there now is the same tire, just a couple years older (with a different rim style).
The laziness part of me says to keep it as is & deal with the rim difference (they're both white, one's triangle cutouts & one's circles). I'm not camping in Beverly Hills after all. :) Plus, like you say, I'd have a non-repaired tire on the ground.
I kinda figured they wouldn't repair it if there was a good chance of failure. Just wanted to see if anyone had any giant red flags.
Thanks!
