Speaking of another question, I got my new CLS c257 with summer tires. Everything was good and nice. I ordered winter tires and sent them to the car dealership and they should switch from summer to winter tires. Summer tires should come to me with UPS / DPD afterwards. Today the tires were with me. What surprised me was the front tire with DOT 5317 and rear with DOT 0118 / 0218. First registration of car is 09.2018. Is anything possible at all or the car dealership has cheated something? Yours sincerely,
