Friends! I bought a set of different-width tires with a radius of 18 for Mercedes in April 2023. I've driven about 32,000 km. Balancing up to 55 grams per wheel. I'm happy with the tires. Since the car is rear-wheel drive, wear is already noticeable on the rear tires, and it's quite decent. Front wear is minimal. This is perhaps the only drawback for me. Still, it's China. The price was the deciding factor back then, and it's still the case today. Good luck on the roads!
