The Ford Ranger is one of the most reliable and versatile mid-size pickup trucks available. Whether you own an older model or a newer one, understanding the Ford Ranger lug size is crucial when replacing wheels, upgrading tires, or performing routine maintenance. Having the right lug nut size ensures a secure fit and prevents issues such as vibrations, uneven tire wear, and potential safety hazards. In this guide, we will cover everything you need to know about the ford ranger lug size, including specifications, compatibility, torque settings, and how to change the lug nuts properly.
What Is a Lug Size?
Lug size refers to the diameter and thread pitch of the lug nuts used to secure a vehicle’s wheels to the hub assembly. It is typically expressed as a combination of two numbers, such as 12mm x 1.5, where:
- 12mm represents the diameter of the lug stud
- 1.5 represents the thread pitch (the distance between each thread)
Knowing the correct lug size is essential to ensure proper installation and avoid any wheel fitment issues.
