Preheat grill to medium-high heat (350° to 400°). Spray grill racks with high-heat cooking spray.
Cut each peach half in half vertically. Add peaches and corn to grill. Grill peaches for 1½ minutes per side. Grill corn until grill marks appear, 4 to 5 minutes, turning occasionally. Remove from grill. Chop peaches and remove corn from cob.
In a medium bowl, combine peaches, corn, cilantro, tomato, cucumber, onion, and serrano; toss well.
In a small bowl, whisk together lime juice, oil, honey, salt, and red pepper. Add to peach mixture; toss gently. Serve with tortilla chips. Garnish with cilantro and lime, if desired.
