For most ribs, wrap them when the bark is set and the internal temperature is around 150–170°F ; a common target is about 165–170°F for spareribs.

Practical rule

  • Baby backs: often wrap a bit earlier if you want to protect tenderness and keep the cook moving.
  • Spareribs: usually wrap around 165–170°F or when the color is deep mahogany and the bark has “set.”
  • Don’t wrap by temp alone: look for bone pull-back and a firm bark, since timing varies by smoker, humidity, and rib size.

Easy cue to use

If you want one simple cue, go by this: wrap when the ribs look right, not just when they hit a number.

After wrapping

Most guides suggest finishing the wrapped ribs until they’re tender, often around 195–203°F internal when done.

TL;DR: Wrap ribs around 165–170°F , once the bark is set and the color looks right.
