When it comes to maintaining and upgrading your 2018 Ford F150, understanding its bolt pattern, tire size, optimal tire pressure, and lug nut size and torque is of paramount importance. But why is this knowledge crucial? Let’s dive in to understand better.

An Overview

The 2018 Ford F150 is a versatile and powerful pickup truck known for its performance and reliability. However, to ensure its optimal performance, the correct bolt pattern, tire size, and tire pressure must be used.

The Bolt Pattern and Lug Nut Size

Bolt patterns are essential to understand for fitting wheels and rims on your vehicle correctly. Additionally, choosing the right lug nut size is crucial for securing the wheels to your F150.

The above table clearly indicates that the 2018 Ford F150, irrespective of the trim, follows the 6x135mm bolt pattern and uses 14×1.5mm lug nuts.

Decoding Tire Size

While picking the right tires for your F150, understanding tire sizes is crucial. The size is usually denoted as a combination of three numbers and two letters, such as P275/65R18. Each part of this code conveys a specific attribute of the tire.

Here’s how to read it:

  • P: Denotes ‘Passenger’, indicating that the tire is designed for passenger vehicles.
  • 275: This is the width of the tire in millimeters from sidewall to sidewall.
  • 65: Known as the ‘aspect ratio’, it’s the height of the tire sidewall as a percentage of the tire’s width. In this case, the sidewall height is 65% of 275mm.
  • R: Stands for ‘Radial’, indicating the construction of the tire.
  • 18: Represents the wheel diameter in inches. This number should match the size of the wheel it’s being mounted on.

Please note that these are the original manufacturer-recommended sizes. However, alternative tire sizes might be used based on your driving conditions and preferences.
