Mercedes A-Class (W169) Wheel Lug Pattern, Offset ET & Center Bore Guide

The Mercedes A-Class (W169) features specific wheel lug patterns crucial for selecting compatible wheels and tires. This guide provides accurate specifications including lug count, PCD (pitch circle diameter in millimeters), offset ET, and center bore for each production year.\n\nUnderstanding the lug pattern, which combines the number of lugs with the PCD, ensures mounting compatibility between the wheel and vehicle hub. The W169 typically uses a 5-lug pattern with PCD measurements that vary by model year and trim.\n\nOffset ET values influence wheel position relative to the suspension and fenders, affecting handling and appearance. Proper offset selection for the W169 ensures safe clearance and maintains OEM performance.\n\nCenter bore dimensions highlight the hub opening size, important for ensuring the wheel sits flush without vibrations. Matching this with the wheel’s center bore guarantees a secure fit. Our catalog also provides rim size contexts related to these specifications to assist in comprehensive wheel selection.
