Why Choose 245 45 R17 Winter Tires for Your Mercedes?
Many Mercedes models, especially in the C, E, and GLC classes, are factory-equipped with 245 45 R17 winter tires. This is for good reason: the combination of tire width and aspect ratio offers an optimal compromise between grip, comfort, and driving stability.
