Australian BYD M9 Factory Tyre Sizes
| Vehicle | BYD Australia listed tyre size |
|---|---|
| BYD M9 | 235/50R18 |
The tyre size is only part of the specification. Confirm the load index, speed rating and whether the wheels are factory or aftermarket before ordering.
How to Check the Correct Replacement
- Read the tyre placard on the vehicle.
- Compare it with the current tyre sidewall.
- Record the full size, load index and speed rating.
- Confirm the wheel diameter, width and whether the setup is staggered.
- Check intended load, towing and driving use.
Can You Change the Wheel or Tyre Size?
A change may be possible, but overall diameter, wheel width and offset, brake and suspension clearance, load and speed ratings, steering clearance and applicable South Australian requirements need to be checked. Do not assume that a setup used on another vehicle is suitable for yours.

For daily Adelaide use, consider wet braking, comfort, road noise and tyre wear. Vehicles used for country travel, towing or unsealed roads may need a different balance. Correct fitting, balancing, pressure setup and wheel alignment remain important.
