Bolt pattern basics
These core facts describe the S197 lug setup you’ll encounter when shopping or swapping wheels.
What "5x114.3" means

- Commonly written as 5x114.3 or 5x4.5 inches.

- Center bore and wheel offset are separate fit factors to verify with the wheel manufacturer.
In short, the wheel bolt pattern you’ll typically encounter for S197 Mustangs is 5x114.3, with hub bore and offset needing confirmation for a precise fit.
Wheel compatibility considerations
When selecting wheels, beyond the bolt pattern, consider how the wheel will align with the hub and calipers inside the wheel well.
- Center bore compatibility: ensure the wheel's center bore matches the hub or use hub-centric rings to eliminate wobble and vibration.
- Offset and width: confirm that the wheel offset and width will fit without rubbing the brake calipers or fenders, especially if you have upgraded brakes.
- Lug nuts and seat type: verify you have the correct lug nut type, seat contact, and thread pitch for the wheel and hub.
- Adapting with spacers/adapters: avoid relying on spacers unless necessary; improper use can affect handling and safety.
- Brake clearance: larger brake kits may require wheels with greater clearance or specific spoke designs to avoid contact.
With proper checks, you’ll maximize compatibility and performance when upgrading or changing wheels on an S197 Mustang.
Summary
The S197 Mustang uses a 5-lug, 114.3 mm bolt circle (5x114.3 / 5x4.5). This pattern is standard across the 2005–2014 Mustang lineup, offering broad wheel compatibility, but always verify hub bore size, offset, and brake clearance with your wheel vendor to ensure a proper fit.
