Mercedes-Benz CLA43 AMG Tyre Size & Wheel Specification Guide
The Mercedes-Benz CLA43 AMG is a high-performance compact sedan powered by AMG engineering and equipped with 4MATIC all-wheel drive.
Because of its performance setup, the CLA43 typically uses staggered tyre sizes to maximise grip, stability and cornering performance.
Understanding the correct factory tyre sizes, wheel dimensions and torque settings is essential when replacing tyres or upgrading wheels.
At Autosport Tyreworld, we regularly service AMG vehicles and help drivers choose the correct tyres for both daily driving and performance handling.
