I’m obviously in the same situation as the previous blogger. I have a 2018 Cadillac ATS premium luxury. I’ve only owned the car for about 5 months, and it looks as though the tires have never been changed on the car. This fall I’d like to replace all 4 tires and I was thinking of replacing them with just regular michelin tires. I’ve never heard of the run flat tires. They do appear to look somewhat small for the vehicle. That being said, has anyone commented on whether or not we can buy regular tires for the car?
