The tire size of the Mercedes-Benz C260 is 17 inches. Mercedes-Benz C260 tire model: Front tire specification 225/45-R17, rear tire specification 225/45-R17, spare tire type is non-full size. Meaning of tire specifications: First, 225 represents the tire width of 225mm. The wider the width, the stronger the grip, making it more controllable during aggressive driving. The following 45 represents the tire aspect ratio. The lower this value, the thinner the tire sidewall, resulting in better sportiness, while a higher value provides better comfort. R stands for radial tire, and the final 17 represents the rim diameter of 17 inches.

I've been driving a Mercedes-Benz C260 for a while, and it usually comes with tires sized 225/45 R18, meaning 225 millimeters wide, 45% aspect ratio, and 18-inch wheels. This size is chosen because it provides good stability in city driving, excellent grip when turning, and isn't too bumpy. Last time I got new tires, the dealer reminded me not to casually change the size, as it could affect speed and odometer accuracy and might increase fuel consumption. Actually, the tire specifications are labeled on the door—just check there. By the way, for winter or mountain driving, ensuring the tread pattern is suitable is more important. In short, this is the standard configuration, but it might vary by year or higher trim levels, so it's best to confirm via the VIN code in the vehicle manual to avoid choosing the wrong ones.

The Mercedes-Benz C260 typically comes with tire size 225/45 R18. In these specifications, 225 refers to the tread width in millimeters, 45 is the aspect ratio (height to width), and 18 represents the wheel diameter in inches. This design provides responsive handling at high speeds and decent noise control, making it quite suitable for daily commuting. If you plan to upgrade your wheels, say to 19 inches, the tires will become thinner and look more stylish, but comfort may decrease slightly, and fuel consumption might increase a bit. It's advisable to measure your old tires and consult a professional shop to ensure compatibility with factory standards and protect the suspension system. Additionally, regularly checking tire pressure and verifying details by entering your vehicle's model year in the safety manual or online tools is crucial.

My Mercedes-Benz C260 is the standard version with tire size 225/45 R18, which provides a well-balanced driving experience. You can find the exact specifications on the sticker located on the driver's door frame. When selecting tires, I always prioritize the original factory specifications because any unauthorized modifications could compromise driving safety and potentially void the warranty. For routine maintenance, I recommend checking tire pressure monthly and replacing tires promptly when significant wear is detected—never delay this.
