Condition

The listed tire DOT codes are:
- Front: 1021 / 1521
- Rear: 0221 / 4021
Because the tires are from 2021, buyers should verify the DOT dates and inspect the tires for age-related deterioration before installation.
Genuine Maserati OEM Wheels
The part numbers 670171185 and 670194792 are identified by multiple wheel specialists as original Maserati Grecale wheel references.
The OEM construction makes this set suitable for customers looking to maintain the original factory appearance and wheel specifications of the Grecale.
Fitment
The advertised application is:
Maserati Grecale
Before ordering, verify the vehicle’s:
- Model year
- Grecale trim
- Brake package
- Approved wheel size
- Tire specification
- VIN
- COC/homologation documentation
Wheel and tire combinations should be checked against the vehicle’s Certificate of Conformity (CoC) or manufacturer’s approved specifications.
TPMS Sensors
The wheels are equipped with RDK/RDC tire-pressure sensors.
Before installation, verify sensor compatibility and battery condition. The vehicle may require TPMS relearning or registration after installation.
Wheel Inspection
Even though the wheels are described as original Maserati components, inspect each wheel for:
- Cracks
- Bends
- Curb rash
- Weld repairs
- Corrosion
- Paint defects
- Previous refurbishment
- Damage around the mounting holes
- Distortion
Because the specific rims have been refinished, buyers should also inspect the quality of the repaint and polished areas.
Tire Inspection
Before fitting the tires, check:
- DOT production date
- Tread depth
- Sidewall condition
- Cracking
- Uneven wear
- Punctures
- Repairs
- Bead condition
- Tire-pressure requirements
The approximately 6.5 mm tread depth applies to the referenced set and should be rechecked on the actual tires being sold.
Installation
Professional installation is recommended.
- Verify all four wheel part numbers.
- Inspect the wheels and tires.
- Check TPMS sensors.
- Mount the wheels.
- Balance all four assemblies.
- Set tire pressures according to the Grecale specification.
- Install compatible center caps.
- Torque the wheel fasteners to Maserati specification.
- Perform TPMS relearning if required.
- Check brake and suspension clearance.
- Complete a road test.
Important Product Notice
The wheel set described here is a staggered 21-inch OEM Maserati Grecale setup. The front and rear wheels have different widths and offsets, so they should not be rotated front-to-rear.
Also, center caps and wheel bolts may not be included unless specifically stated. One documented Grecale wheel listing notes that center caps and wheel bolts are separate from the wheel package.
