In this article, we will guide you through the process of converting the wheel, tire, and lug setup on a 2007 Chevrolet Silverado 2500HD. We will transform the existing 8-lug wheel configuration to the newer and more common 8x180 pattern. Additionally, we will be installing factory OEM 20-inch wheels with BFGoodrich all-terrain tires measuring 33 inches. Follow the step-by-step instructions below to complete this conversion on your own.

Step 1: Gather the Necessary Tools and Equipment

Before we begin, make sure you have the following tools and equipment:

  • Jack (a sturdy floor jack is recommended)
  • Cobalt brushless impact wrench with a 24-volt, half-inch drive, and a 4 amp battery
  • 7/8 or 22-millimeter socket
  • 19-millimeter lug nut socket
  • Torque wrench

Step 2: Remove the Factory Wheel Covers and Lug Nuts

Start by using the impact wrench to remove the factory wheel covers. Use a 7/8 or 22-millimeter socket to remove the lug nuts. The torque required for these lug nuts is about 1300-1400 foot-pounds, so ensure you are using a high-torque impact wrench.

Step 3: Install the Adapter Spacers

Next, it’s time to install the adapter spacers. The lug nuts that come with the spacers are 19-millimeter in size. Make sure to torque the wheels and check the lug nuts to ensure they are securely fastened.

Step 4: Trim the Original Wheel Studs

You may notice that the original wheel studs are taller than the 1.5-inch adapter spacers. These studs will need to be trimmed. Use a 4-inch angle grinder with a cutting wheel to trim off the excess length. Make sure you only trim the nipple on the end of the stud and not the threaded portion.

Step 5: Replace the Retaining Nut Washer

Remove the original retaining nut washer that kept the rotor on. You will not need this washer anymore since you will be using the lug nuts that came with the spacers.

Step 6: Install the New Wheels and Tires

Start by placing the lug nuts provided with the spacers inside the new wheels. Make sure not to cross-thread the lug nuts. If you have a torque wrench, tighten the lug nuts to 90 foot-pounds. If not, tighten them firmly in a back and forth crisscross pattern.

Step 7: Complete the Installation

Finally, install the new wheels and tires onto the 180-millimeter bolt pattern. Use the factory lug nuts to hand-tighten the wheels onto the spacers.

Congratulations! You have successfully converted the wheel, tire, and lug setup on your Chevrolet 2500HD. Enjoy your new setup and ensure to regularly check the lug nuts for proper torque and tightness.

Key Points to Consider

  • The purpose of this DIY guide is to assist individuals in converting their Chevrolet 2500HD from 8x6.5 to 8x180 bolt patterns for the wheel, tire, and lug setup.
  • It is crucial to gather all the necessary tools and equipment before starting the conversion process. This includes a jack, cobalt brushless impact wrench, sockets, torque wrench, and an angle grinder.
  • The factory wheel covers and lug nuts need to be removed using an impact wrench. Make sure you have the appropriate socket size to prevent any damage to the lug nuts.
  • The adapter spacers should be installed carefully, ensuring the lug nuts are torqued properly.
  • The original wheel studs will need to be trimmed using an angle grinder. Be cautious not to cut any of the threaded portion, as this may cause problems with wheel installation.
  • Replace the original retaining nut washer with the lug nuts provided with the spacers.
  • When installing the new wheels and tires, make sure to follow a back and forth crisscross pattern to ensure even tightening.
  • Regularly check the lug nuts for proper torque and tightness to avoid any safety issues.

By following this step-by-step guide, you can confidently convert the wheel, tire, and lug setup on your Chevrolet 2500HD. Remember to take necessary precautions and consult a professional if you are unsure about any step in the process. Enjoy your new setup and safe travels!
