Mercedes-Benz C-Class
Standard C-Class fitment guide for C180 and C200 W204, W205, and W206 road cars. AMG C63 content now lives in its own AMG guide.
The standard C-Class recommendation starts from the actual W204, W205, or W206 chassis, not from a C63 stance photo. LFI checks PCD, centre bore, brake package, tyre diameter, road use, and hardware seat before production.
W204, W205, and W206 use different offset and tyre-clearance logic.
Sidewall, wet-road behaviour, ramps, and steering lock stay part of the specification.
C63 brake and rear-fitment content has been moved into the AMG C63 guide.
| Area | Guide value | Fitment note |
|---|---|---|
| PCD | 5x112 | Confirmed per car. |
| Centre bore | 66.6 / 66.56 | Machine hub-centric to the confirmed vehicle. |
| Recorded sizes | 19x8.5 ET42 / 19x9.5 ET45 / 18x8 ET35 / 18x9 ET43 / 19x8.5 ET43 / 19x9.5 ET47 / 19x8.5 ET48 / 19x9.5 ET45 / 18x9 ET48 / 18x8 ET30 / 18x9 ET42 / 19x8.5 ET40 / 19x9.5 ET45 | Final tyre pairing depends on chassis and ride height. |
| C63 | Separate AMG guide | Do not use C63 offsets as the normal C-Class shortcut. |
Modern W206 AMG Line fitment with staggered width and conservative road clearance.
Final tyre pairing, ride height, hardware seat, centre cap, brake template, and load target are checked against the actual vehicle before production.
| Use case | Starting direction | Why it works |
|---|---|---|
| W204 comfort | 18x9 ET48 or 19x8.5 / 19x9.5 high-offset rear | Keeps rear fender clearance under control. |
| W205 road stance | 18x8 ET35 / 18x9 ET43 | Balances sidewall, offset, and daily road behaviour. |
| W206 modern stagger | 19x8.5 ET40-43 / 19x9.5 ET45-47 | Matches the larger W206 body without copying AMG C63 sizing. |
C-Class wheel strength is not only a vertical load number. LFI reviews radial load, braking torque, cornering load, hub-pad stress, bolt-seat stress, and spoke-root reaction together.
Strong road-use target for standard C-Class applications.
Practical static torque-load reference for selected C-Class forged specifications.
Mercedes ball-seat and conical hardware requirements are checked before machining.
| Load case | What LFI reviews | Why it matters |
|---|---|---|
| Radial vehicle load | Vehicle mass, tyre package, and selected wheel load target | Confirms the wheel is suitable for road use. |
| Torque load | Braking, acceleration, bolt seat, and spoke-root reaction | Captures forces a radial-only claim misses. |
| Cornering load | Tyre grip, offset, concavity, and ride height | Keeps stance and structure aligned. |
| Combined static load case | Radial, torque, cornering, and hub fitment | Protects the final specification. |
Do not copy C63 rear offsets into a normal C-Class. C63 arches, brakes, tyres, owner stance goals, and body clearance can be different from C180 and C200 road cars.
Spoke profile, barrel contour, and backpad are reviewed first.
Rolling diameter and shoulder profile are matched to the chassis.
Concavity and finish are selected around the actual car.

LFI supplies made-to-order forged wheels worldwide with remote fitment checks and DDP options where available.
Singapore customers can visit 76 Playfair Road, #01-03 to review finishes, concavity, and wheel samples.
No. The C63 content has been moved to the Mercedes-AMG C63 guide. This page now covers standard C-Class C180 and C200 fitment logic.
The W204, W205, and W206 C-Class rows in this guide use 5x112. LFI confirms the exact vehicle before machining.
Recorded C-Class rows use 66.6 and 66.56 mm references. Hub-centric machining is confirmed per build.
Yes. LFI machines the required width, offset, and brake clearance into the wheel specification when the vehicle geometry allows it.
LFI positions 690 kg per wheel as a strong road-use target for standard C-Class applications, with more reserve reviewed where the use case requires it.
