Place the bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain the bacon slices on paper towels. Crumble bacon when cool enough to handle.

Heat vegetable oil in a large soup pot over medium heat and brown tri tip in the hot oil, working in 4 batches, until beef is browned and no longer pink inside, about 5 minutes per batch. Return all cooked beef to pot and stir sweet onion, garlic, jalapeno peppers, chili powder, cumin, and paprika into meat; cook and stir until onion is translucent, about 5 minutes.

Pour tomatoes, beer, tequila, oregano, salt, and black pepper into mixture, scraping up and dissolving any browned bits of food on the bottom of the pot. Stir reserved bacon, beef stock, chipotle peppers, and steak sauce into the mixture; bring to a boil.

Reduce heat to low and stir in Mexican-style corn and green bell pepper. Cover and simmer chili, stirring occasionally, until thickened and meat is very tender, about 3 hours.
