Audi westmont leased me a brand new 2019 a6 last november 12, 2018. they claim "all" of audi's 2019 a6's come with "summer tires" on them and getting an "all season" or "winter" tire is not possible unless i pay another $2,690.83 for four more "wheels and winter tires". i drove the vehicle for two months on their "summer tires" bridgestone turanza t005 summer tires. on two separate occasions with less than one inch of snow on the ground, i totally lost control of the car while braking. my wife refused to ride again with me with the tires that came with the car. i finally went back in and had to purchase from them four new sotozero3 winter tires and four new wheels. i now have 8 new tires and 8 new wheels. my complain is with audi, not the dealer. selling or leasing these vehicles with summer tires only in a geographical area that experiences winters such as suburban chicago, is a disaster waiting to happen. audi needs to be stopped before someone dies. thank you!
