How to Read Wheel Offset & Measurements
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
Convertibles lose some of the structural rigidity a fixed roof provides, which means the suspension and wheels end up doing more of the work to keep the chassis composed. A forged wheel keeps unsprung mass down without sacrificing the strength margin the factory built in — useful on a platform that's already managing extra flex.
The Mercedes-Benz SLK Edition 10 runs a 5x112 bolt pattern, 66.6mm center bore, and a F: 17x7.5J wheel from the factory. Our Flush Fitment reference is F 18x8.0J ET35 / R 18x9.0J ET32, which tucks the tire under the fender lip on a stock-height Mercedes-Benz SLK Edition 10. Our Maximum Aggressive reference is F 19x8.5J ET32 / R 19x9.5J ET28 — beyond that offset, expect rubbing against the inner fender liner under compression without further trimming.
Mercedes-Benz SLK Edition 10 OE Wheel Specs
The 2007 Mercedes-Benz SLK Edition 10 (Limited Roadster) uses a 5x112 bolt pattern with a 66.6mm center bore. Factory wheels are F: 17x7.5J R: 17x8.5J.
Why the factory spec works for most owners:
- Balances ride comfort with everyday drivability
- A commonly used size for this vehicle class, supporting parts and tire availability
- Maintains clearance for the factory suspension and brake components
- Provides stable, predictable handling across normal driving conditions
Flush Fitment
For a flush look with minimal rubbing, F 18x8.0J ET35 / R 18x9.0J ET32 is the recommended starting point on a stock or mildly lowered Mercedes-Benz SLK Edition 10.
Maximum Aggressive Fitment
F 19x8.5J ET32 / R 19x9.5J ET28 is a more aggressive reference setup. Beyond this, expect rubbing under compression without fender rolling or camber correction.

Decision Guide
Offset & Backspacing Reference
Backspacing is calculated as wheel width (in) ÷ 2 + offset (mm) ÷ 25.4 + 0.5 (flange allowance):
- OE: F 17x7.5J ET37 → ~5.71″ F backspacing, R 17x8.5J ET37 → ~6.21″ R backspacing
- Flush: F 18x8.0J ET35 → ~5.88″ F backspacing, R 18x9.0J ET32 → ~6.26″ R backspacing
- Max: F 19x8.5J ET32 → ~6.01″ F backspacing, R 19x9.5J ET28 → ~6.35″ R backspacing
Want to check a different width or offset before you order? Use our Offset & Backspacing Calculator to solve the numbers yourself, or looking for your exact Mercedes-Benz spec, or want a wheel built to a custom offset for your Mercedes-Benz SLK Edition 10? Contact ANKUSI with your bolt pattern and offset target and we will confirm the correct forged wheel spec for your build.

Wheel Installation Reference: Torque, Thread & TPMS
Thread & Fastener: M14x1.5, ball-seat lug bolt.
Factory Torque Spec: 130 Nm (96 ft-lb). Sedan/coupe platforms (E-Class, CLS, SL and similar) generally use the shorter 27mm bolt at this spec.
TPMS: Vehicles built before the 2008 model year were not federally required to carry factory TPMS in the US, though many manufacturers adopted it earlier; verify whether your specific build has TPMS before ordering sensor-compatible wheels.
Tire Pressure: Always set tire pressure to the value on your vehicle's tire placard (driver's doorjamb or glovebox), not the max PSI printed on the tire sidewall — this is trim- and tire-size-specific and stays the same reference point when you switch to a different wheel and tire combination.
Reference data compiled from published OEM service specifications and cross-checked against independent repair sources; always confirm against your owner's manual or door-jamb placard before installation.
