Before attempting to install them, you must verify:
* Bolt Pattern: Find the bolt pattern for both the 2007 and 1996 trucks. This is usually expressed as something like 6x139.7mm (6 lug nuts on a 139.7mm diameter circle). These MUST match exactly.
* Center Bore: The center bore is the hole in the wheel that fits over the hub on your truck. It must be the correct size, or a hub-centric ring will be needed (but even then, it might not be ideal).
* Wheel Offset: This determines how far the wheel mounts in or out from the hub. A significant difference can cause clearance issues with the suspension or fenders.
* Wheel Diameter: While it might *seem* like a larger diameter wheel would work (depending on tire size and suspension lift), it can impact your speedometer accuracy and potentially cause rubbing.
You can find this information on your truck's owner's manual, online resources dedicated to Chevy truck specs, or by having the rims physically measured by a tire shop. It's best to avoid any assumptions and get the measurements to ensure a safe and proper fit. Incorrectly fitted wheels are a serious safety hazard.
