Remove silver skin from pork, leaving a thin layer of fat. Pat tenderloins dry; rub with oil, and coat with spice mixture. Let pork stand at room temperature 30 minutes. Pull back husks from corn; remove and discard silks. Tie husks together with kitchen string to form handles. Rinse and dry exposed cobs.
Preheat grill to 350° to 400° (medium-high) heat. Grill pork, covered with grill lid, 10 to 12 minutes on each side or until a meat thermometer inserted in thickest portions registers 145°.

Thinly slice one and one-third tenderloins; reserve remaining two and two-thirds tenderloins for Pork Tenderloin Wraps and Pork, Mango, and Tomato Salad.
Meanwhile, grill corn, covered with grill lid, 15 minutes or until golden brown, turning occasionally. Sprinkle with desired amount of salt and pepper. Reserve 2 ears corn for later use. Serve remaining corn with Grilled Pork Tenderloins.
