I leased a 2018 BMW X3 from BMW of Norwood, MA. For my lease, I am allowed 36k miles. I have 26.5k miles on the car and they are telling me the tires are bald and I need to replace all the tires. When I questioned the service advisor as I had googled the tire and it said unless unusual wear and tear on the car the tires should last 60k - they said that the lifespan of the tire is 26K. Due to COVID, I am well within the 36K and there has been no unusual wear and tear. I think that if this is the case then BMW should let the person leasing know that although they are allowed 36k miles - they will need to replace all the tires at 26k. I took the car to a mechanic and he said the tires are not bald.
