Mercedes C Class wheel fitment — T-Model 203K
Overview
The Mercedes-Benz W203 is the second generation of the compact executive car series, introduced in March 2000 with production beginning in March 1999. It succeeded the first-generation W202 and was available as a sedan, station wagon, and liftback body styles. The W203 featured an extended range of engines including inline-four and V6 petrol engines alongside inline-four and -five diesel options, with later models receiving a V6 diesel engine. Notably, this generation saw the introduction of common rail direct fuel injection for diesel variants and variable geometry turbochargers. A six-speed manual gearbox was optional on some models except for the C320 and C32 AMG.

Aftermarket wheel sizes — read per position:
| Position | Width | Offset |
|---|---|---|
| Front | 6.5J–8J | ET22–ET38 |
| Rear (staggered) | 8J–11J | ET20–ET37 |
As a rule, each extra 1J of width wants roughly +8–10 ET to keep the wheel tucked. The exact offset and any spacer are confirmed by the fit-check.
