OEM wheel sizes for the BMW G99 M5
From the factory, the BMW M5 is delivered with staggered wheel sizes designed to handle high torque and provide stability at speed.
OEM wheels prioritize durability, comfort and emissions efficiency. However, many owners choose to upgrade wheels to improve both performance and aesthetics.
The OEM fitment is:
Front axle 10.5Jx20 ET28 with 285/40ZR20 111Y
Rear axle 11Jx21 ET28 with 295/35ZR21 110Y
Center Bore / Hub Bore: 66.6 mm
Bolt Pattern (PCD): 5x132
The new BMW G90 and G99 M5 introduce a new 5x132 bolt pattern, which changes wheel compatibility compared to previous M5 generations.
Forged wheels vs OEM wheels
Forged wheels are significantly stronger and lighter than most OEM wheels. Reducing unsprung weight improves steering response, braking feel and overall agility.
Advantages of forged wheels:
- Lower rotational mass
- Higher strength
- Custom finishes and sizing
- Improved heat resistance

Common wheel sizes for BMW G99 M5
Most performance setups use staggered configurations with larger rear wheels.
Typical aftermarket setups include:
We start with the OEM+, this is the most chosen option. It keeps the same width and diameter as original, but we alter the offset, for a better fitment. The so called flush fitment, where the wheel / tire sits perfectly flush with the fender, of course without rubbing. Due to our experience, we know and tested this fitment for the original height, but also for lowered BMWs.
Below are the most common wheel setups for the BMW G99 M5. Each configuration offers a different balance between comfort, stance and performance.

| Front tires | 285/40-20 |
| Rear tires | 295/35-21 |
| Fitment | 21/21 Square |
| Front wheels | 11.0 x 21" |
| Rear wheels | 11.0 x 21" |
| Front tires | 295/35-21 or 305/35-21 |

Understanding offsets
Offset determines how far the wheel sits inward or outward in the wheel arch in combination with the width of the wheel. Correct offset ensures proper clearance for suspension components and brake systems.
Incorrect offset can cause:
- Rubbing
- Poor handling
- Uneven tire wear
Professional fitment advice is recommended when selecting custom wheels.
With more than 20 year of experience in defining the best possible fitment for your taste, we are the shop to go to and get the best possible wheels.
Tire sizing and performance
Tire selection is just as important as wheel sizing. Performance tires improve grip, braking and steering response.
Most high-performance setups use staggered tire widths to maximize rear traction while maintaining steering precision at the front. For the M5 we als have a square setup, with the same tire size in the front and rear.
Fitment and lowering
Lowering the suspension changes the relationship between wheel, tire and fender clearance.
If you're considering lowering, see: BMW G90 & G99 M5 suspension and lowering guide
Proper fitment ensures:
- No rubbing under compression
- Balanced handling
- Clean stance
Choosing the right wheel setup
The ideal setup depends on how the vehicle is used:
- Daily driving → forged wheels with OEM-style fitment
- Sport driving → wider rear setup
- Show builds → aggressive fitment and custom finishes
