Preheat the oven to 350 degrees F (175 degrees C).

Preheat an outdoor grill for high heat and lightly oil the grate.

Mix salt, chili powder, garlic powder, and onion powder together in a bowl. Rub spices on ribs.

Sear rib tips on the preheated grill until spices start turning black, 3 to 4 minutes.

Pour sauerkraut into a large baking pan; mix in grilled rib tips. Cover tightly with aluminum foil.

Bake in the preheated oven until ribs are tender, about 2 hours. Remove from the oven, stir, and let sit for 5 to 10 minutes.
