BMW 420i Gran Coupé Upgrade: RAYS 57CR and Continental MC7 in Adelaide
Quick answer: This BMW 420i Gran Coupé came to Autosport Tyre World Magill for a new wheel and tyre package. The finished combination uses 19-inch RAYS Gram Lights 57CR wheels, 245/40R19 Continental MaxContact MC7 tyres at the front, and 255/40R19 Continental MaxContact MC7 tyres at the rear.
The result gives the white 420i a clean five-spoke motorsport look while retaining a practical 19-inch tyre package for Adelaide road use.
The BMW 420i wheel and tyre package
| Position | Wheel | Tyre |
|---|---|---|
| Front | 19-inch RAYS Gram Lights 57CR | Continental MaxContact MC7 245/40R19 |
| Rear | 19-inch RAYS Gram Lights 57CR | Continental MaxContact MC7 255/40R19 |
This is a staggered tyre setup: the rear tyre is wider than the front. Wheel width, offset, brake clearance, load rating and the exact BMW variant must all be checked before ordering. A fitment shown on one vehicle should not be treated as automatic approval for every BMW 4 Series.
Why this combination works visually
The 57CR's simple five-spoke design leaves the brakes visible and suits the long, low profile of the BMW 4 Series Gran Coupé. The 19-inch diameter fills the guards without relying on an oversized wheel, while the staggered Continental package gives the rear of the vehicle a broader stance.
For available specifications, see the RAYS Gram Lights 57CR product listing. Final colour, PCD, width and offset should be confirmed with our team because the online listing may include fitments for several vehicles.

Why alignment matters after fitting wheels and tyres
New tyres cannot correct an existing toe or camber problem. If the steering wheel is off-centre, the vehicle pulls, or the old tyres show uneven wear, the geometry should be inspected. A professional wheel alignment in Adelaide can help place the tyres correctly on the road and protect the new set from avoidable wear.
We have not listed before-and-after alignment measurements for this vehicle because none were supplied for this case study.
BMW fitment checks before ordering
Before fitting aftermarket wheels to a BMW 420i, confirm:
1. exact model, generation and build year;
2. wheel diameter, width, offset and PCD;
3. centre-bore and mounting hardware requirements;
4. brake and suspension clearance;
5. tyre load and speed ratings;
6. overall diameter and clearance at full steering lock;
7. tyre-pressure monitoring system requirements.
Frequently asked questions
What tyres were fitted to this BMW 420i?
Continental MaxContact MC7 tyres in 245/40R19 at the front and 255/40R19 at the rear.
Are RAYS 57CR wheels available for every BMW 4 Series?
Not in one universal specification. PCD, width, offset, centre-bore, brake clearance and tyre size must be matched to the exact vehicle.
Should a BMW receive a wheel alignment after new tyres?
An alignment inspection is sensible when tyres are replaced, especially if there is pulling, an off-centre steering wheel, suspension work or uneven wear. The required adjustment depends on measured geometry.
