I have a 2017 e-Tron with 20k. The Conti tires have not been great. We just blew a drivers side rear tire in a pothole last night. $225 towing charge to get the car home. But the question is, what if I replace both Contis on the rear with Michelins? And run with the front Contis for another 10-20k? Some cars are worse than other about mixed tires.
