Use these two references before ordering: the left diagram shows where each spec (PCD, center bore, offset, width and diameter) is measured on the wheel; the right diagram shows how positive, zero and negative offset shift the wheel face relative to the hub centerline.
ANKUSI Engineering Expert Advice
A sedan's wheel spec is a balance point the factory tuned between ride comfort, steering feel, and everyday durability. Forging lets us hold that same structural margin while cutting rotational mass, which is where most of the real-world benefit — quicker steering response, marginally better ride — actually comes from.
The Kleemann Mercedes-Benz C 55K S8 ships from the factory on a 5x112 bolt pattern with a 66.6mm center bore and a F 19x8.5J ET35 / R 19x9.5J ET35 wheel. Our flush reference for the Kleemann Mercedes-Benz C 55K S8 is F 19x8.5J ET30 / R 19x9.5J ET32.; our maximum aggressive reference is F 19x9J ET28 / R 19x10J ET30. — beyond that, expect clearance issues against the fender liner without further modification.
Kleemann Mercedes-Benz C 55K S8 OE Wheel Specs
The Kleemann Mercedes-Benz C 55K S8 ships from the factory on 5x112 bolt pattern wheels with a 66.6mm center bore. The stock wheel size is F 19x8.5J ET35 / R 19x9.5J ET35, offering a balanced ride that suits most owners without any rubbing or clearance concerns.
Why the factory spec works for most owners:

- Lower unsprung weight than larger aftermarket wheels helps ride quality and acceleration.
- Guaranteed clearance against brake calipers and suspension components.
Flush Fitment
For a flush look without any body modification, most Kleemann Mercedes-Benz C 55K S8 owners run F 19x8.5J ET30 / R 19x9.5J ET32. This setup tucks the wheel face closer to the fender lip while staying within safe load and clearance limits.
Maximum Aggressive Fitment
Owners chasing a more aggressive stance push to F 19x9J ET28 / R 19x10J ET30. Chassis: Kleemann coilovers or sport springs (W203). Brakes: Large front caliper clearance mandatory. Tires: 225/35 R19 F, 255/30 R19 R. Clearance should be verified before ordering, especially on lowered cars.
