Introduction
In this article, we will explore the process of converting the lug pattern on a 2007 Silverado 2500HD from 8x6.5 to the newer style of 8x180. This conversion will allow you to use factory OEM 20-inch eight-lug wheels, along with BFGoodrich All-Terrain tires, giving your truck a fresh look and improved performance. We will provide a detailed step-by-step guide for the DIY process, along with essential tips to ensure a successful conversion.
Step 1: Gather the necessary tools
To begin the conversion process, you will need a sturdy floor jack to lift the truck off the ground, allowing you to remove the wheels. Additionally, it is essential to have a 24-volt cobalt brushless impact half-inch drive with a 4-amp battery to easily remove the factory covers and lug nuts. Make sure to have a 7/8 or 22-millimeter socket for removing the covers, and a 19-millimeter socket for installing the new lug nuts.
Step 2: Remove the factory covers and lug nuts
Using your impact wrench, remove the factory covers from the wheels with the 7/8 or 22-millimeter socket. Then, use the same socket to remove the lug nuts. These lug nuts are typically torqued to around 1300-1400 foot-pounds, so a powerful impact wrench is necessary for the task.
Step 3: Install the adapter spacers
Next, install the adapter spacers onto the wheel studs. It is important to note that the original studs may be taller than the 1.5-inch adapter spacer. In this case, the studs will need to be trimmed to ensure a proper fit. However, only the nipple portion of the studs needs to be cut, while the threaded portion remains intact.
To trim the studs, use a four-inch angle grinder with a cutting wheel. Carefully trim off the excess nipple portion, ensuring that the studs are flush with the adapter spacer. This will prevent any interference when mounting the wheels.
Step 4: Torque the lug nuts
After installing the adapter spacers, it’s time to torque the lug nuts. Use the lug nuts that came with the spacers, as they are designed to fit properly. Start by hand-tightening the lug nuts and then use a torque wrench to tighten them to 90 foot-pounds. It is important to follow a crisscross pattern when torquing the lug nuts for a secure fit.
Step 5: Install the new wheels and tires
With the lug nuts properly torqued, it’s time to install the new wheels and tires. If you have a set of wheels and tires with an 8x180-millimeter bolt pattern, they can be easily mounted onto the newly installed adapter spacers. Ensure that the wheels are aligned properly with the lug nuts and start by hand-tightening the lug nuts. Once again, use a torque wrench to tighten them in a crisscross pattern to the recommended torque specification.
Step 6: Final checks and finishing touches
After installing the new wheels and tires, perform a final check to ensure that all lug nuts are properly torqued. Inspect the wheels and tires for any signs of misalignment or damage. If everything looks good, you are ready to hit the road with your upgraded Chevrolet 2500HD!
