Mercedes A Class wheel fitment — A-Class Br177 Facelift
Overview
The Mercedes-Benz A-Class Br177 Facelift is the fourth generation of the subcompact executive car manufactured by Mercedes-Benz. Introduced in 2018, it marks the first time the A-Class was offered as a sedan alongside its traditional hatchback variant. This model features front-wheel drive and all-wheel-drive options (4MATIC) and has been designed to compete in the entry-level luxury segment with enhanced dimensions compared to previous generations.
History & notable variants
The fourth generation A-Class, launched at the Frankfurt Motor Show in 2018, was a significant milestone for Mercedes-Benz as it expanded its market reach into North America. Notable changes include an increase in size and improved technology integration, making it more competitive with other luxury subcompact offerings. The model has received updates since its launch to enhance features and performance.
Mercedes A Class wheel fitment
Everything below is what the fit-check uses for Mercedes A Class wheel fitment: the factory bolt spec first, then the width and offset window that clears the arches and the brakes on the Mercedes A-Class Br177 Facelift.
| Bolt pattern (PCD) | 5x112 |
| Centre bore | 66.6 mm |
| Bolt / thread | M14x1.5 (bolts) |
| Wheel-bolt torque | 125 Nm |
| Seat type | radius |
| Factory setup | square |
| TPMS | direct |
| Run-flat | Yes |
Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 6.5J–8.5J | ET30–ET50 |
Go wider and the offset has to rise with it, about 8 to 10 ET per extra 1J, or the wheel pokes past the arch. The fit-check settles the exact offset and any spacer.
