Preheat the smoker to 225 degrees.
Remove the membrane from the bone side of the ribs.
Brush the spare ribs with a light layer of olive oil.
Combine all other ingredients to create a rub. Season the spare ribs with the rub, making sure to cover all sides of the meat.
Place the ribs bone side down in the smoker and smoke for 3-4 hours.
If desired, slather the spare ribs in your favorite barbecue sauce when 30-45 minutes of smoking time is left.
Remove the ribs from the smoker. Wrap them loosely in foil and rest and room temperature for 10-15 minutes before serving.
