Preheat the grill to medium-high heat (around 400°F), setting it up for two-zone cooking with one side for direct heat and the other for indirect heat.
Sprinkle the dry rub on all sides of the pork chops. Let them sit to soak up the rub for 5 minutes.
In a large bowl, combine mangos, corn, red onion, red bell pepper, cilantro, and jalapeño pepper. Squeeze the lime juice over the mixture and gently toss to combine. Season with salt and pepper to taste, and adjust the lime juice if needed. Cover the salsa and refrigerate for at least 30 minutes to allow the flavors to meld together.
Lay the pork chops on the hottest part of the grill and sear each side for about 2 minutes.
Take the chops off the hot side and move them to the indirect heat. Cook for an additional 5-6 minutes per side or until the internal temperature is 140°F for medium.
Transfer the chops to a plate and let them rest for 5 minutes. The internal temperature should rise to 145°F.
Serve the salsa with tortilla chips, grilled fish or chicken, or as a topping for tacos or salads.
