Do they have tire department

Yes

Yes, they do.

Yes they do but I don't recommend this Walmart tire center at all. The rest of the store is fine but the tire center sucks. They aren't managed back there so you might get what you paid for but I doubt it.

Yes they do, and oil and battery the whole works that u would get at any Walmart they do just as rest and when pulling in go to the side u will see automotive and park and go in the doors
