Thanks for taking a look guys - up for sale is a set of 4 Continental ContiSport Contact 3's from my 2018 M2. These came off the car at 230 miles and are virtually brand new. The fronts measure a 7.6mm depth and the rears 6.9mm. I didn't have a proper gauge but that measurement should provide an accurate reading : ) Feel free to ask any questions at all. I will ship them if you want or deliver anywhere within a 100 miles radius of Sacramento. Photos of sizes and date codes are provided as well as the measurements. Thanks so much!
