What is the tire specification for the Mercedes GLC43?
2 Answers
The tire specification for the Mercedes GLC43 is 255/40R21. Tire Introduction: Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. Typically installed on metal rims, tires support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain driving performance. Tire Performance: Tires are often used under complex and demanding conditions, enduring various deformations, loads, forces, and temperature extremes during operation. Therefore, they must possess high load-bearing capacity, traction performance, and cushioning ability. Additionally, they require high wear resistance, flexibility, and low rolling resistance with minimal heat generation. Half of the world's rubber consumption is used for tire production, highlighting the significant demand for rubber in tire manufacturing. Tire Specifications: Specifications represent the geometric parameters and physical performance indicators of a tire. Tire specifications are commonly expressed as a set of numbers, where the first number indicates the tire section width and the second number denotes the rim diameter, both measured in inches.
I noticed that the Mercedes-Benz GLC43 AMG typically comes with a sporty tire setup of 255/45 R20 in the front and 285/40 R20 in the rear as part of the factory AMG Performance Package. This size configuration is quite aggressive, with significantly wider rear tires that deliver enhanced traction, especially noticeable during spirited driving. Having driven 30,000 km on this set, I can attest to their exceptional cornering stability, though they require extra caution on rough roads. The 20-inch wheels paired with these low-profile tires undoubtedly look stunning, but the thinner sidewalls make them prone to bulges when hitting deep potholes, so regular tire pressure monitoring is essential. For replacements, I'd recommend going straight for performance tires like the Michelin Pilot Sport 4S – though pricier, their wet-weather grip and durability justify the cost. A quick tip: specifications may vary slightly across model years, so always verify the sidewall-engraved parameters when purchasing a used vehicle.
