Are the 10 lug wheels a different bolt pattern than the late model gm wheels, like on say a GM motorhome chassis with 19.5" wheels? Has anyone attempted to install aftermarket wheels on their truck, like say alcoas? or do they not make a wheel that fits our size and our bolt pattern? Or am i stuck with just chroming the stock wheels?

Clearing the rear drums is the major problem with the 19.5" wheels. Some clear, some don't. | | | | | Joined: Feb 2006 Posts: 162 Wrench Fetcher | | Wrench Fetcher Joined: Feb 2006 Posts: 162 | so the late model wheels will bolt right up, provided the drums clear? What is a "hubcentric" ring?

The lugs are only designed to hold the wheel on, not carry the weight of the truck. The newer wheels will bolt up, but the hole in the center of the rim is larger than the raised ring on the hubs. To properly and safely use the newer wheels, you need to machine metal rings that fit between the wheel center hole and the ring on the hub.
