They kind of looked like they could have gone longer. Normally baby backs take 3-4 hours and spares around 5-6 with those temps. I just noticed there wasn't much pull back from the bone.
I did a rack of backs the other week at 275 and they never got tender, even after wrapping, and I let them run for 6 hours! Had steady temps as well. Have no idea what the hell happened. I wondered if it was the ribs themselves. Maybe just the cook too. Never happened before.
Keep it up man, you're gonna nail it!
