Tires are one thing the sales department looks at on a lease return - and they’ll ding you for mismatched or worn tires.
While the service department will throw on cheap set of tires if they are going to sell the car(if the car is nice enough at turn-in, it will more than likely become a CPO rather than getting shipped off to Manheim or ADESA/Carvana) a new set of a moderately-priced tires; not Chinese stuff like LingLong but not Michelin either but something like General, Sumitomo/Falken, Toyo or Firestone won’t hurt and makes it more likely you’ll walk away from the lease without penalties.
