Ford Sport Trac Wheel Lug Pattern, Offset, and Center Bore Reference

This Ford Sport Trac wheel lug pattern reference provides detailed specifications for each model year, ensuring precise wheel fitment and compatibility. The lug pattern, defined as lug count × pitch circle diameter (PCD), varies slightly across model years to accommodate factory wheel designs.\n\nIn addition to lug pattern, offset (ET) and center bore measurements are critical to proper wheel mounting and clearance. Offset dictates wheel positioning relative to the hub, while center bore ensures the wheel centers correctly on the axle. Correct rim sizes, including diameter and width, are also outlined to maintain OEM fitment standards.\n\nUse this year-sorted Ford Sport Trac guide to find the exact lug pattern, offset, and center bore specifications, enabling informed decisions when selecting aftermarket or replacement wheels. This helps maintain vehicle safety, performance, and aesthetic appeal without compromising fit or function.

FAQ

What is the typical lug pattern for the Ford Sport Trac?
The Ford Sport Trac generally uses a 6x139.7 mm lug pattern, but specific years may vary slightly. Always verify the exact pattern for your model year.
Why is wheel offset (ET) important for Ford Sport Trac wheels?
Wheel offset determines how far the wheel sits inward or outward from the hub, affecting handling, clearance, and aesthetics. Proper offset ensures correct fit and prevents rubbing or stress on suspension components.
What role does center bore measurement play in wheel fitment?
The center bore is the diameter of the hole in the wheel that fits over the mounting hub. Matching the center bore precisely helps center the wheel and reduces vibrations during driving.
