Will Chevy wheels fit a 1994 Nissan d21?

It's unlikely that Chevy wheels will fit a 1994 Nissan D21 without modification, and even then, it's not guaranteed. The bolt patterns (number of lug nuts and their spacing), wheel offset, center bore size, and potentially hub diameter are all crucial factors. These dimensions are rarely the same across different makes and models, even within the same class of vehicle.

To know for sure, you need to determine the following for both the Chevy wheels and your 1994 Nissan D21:

* Bolt Pattern: This is expressed as a number, e.g., 5x114.3 (five lug nuts on a circle with a diameter of 114.3mm). Find this information on the wheel itself (often stamped) or in the vehicle's owner's manual.

* Wheel Offset: This indicates how far the wheel mounting surface sits in relation to the centerline of the wheel. Positive offset means the mounting surface is closer to the outside of the wheel, negative the opposite.

* Center Bore: The diameter of the hole in the center of the wheel that fits over the hub.

* Hub Diameter: The diameter of the hub on your Nissan D21.

Only if *all* these specifications match will the wheels fit directly. Even with matching bolt patterns, offset differences can cause clearance problems with suspension components or the fenders.

In short: Don't assume compatibility. Find the specifications mentioned above and compare them before attempting to mount the wheels. If you're unsure, consult a tire professional or use a wheel compatibility checker online (many exist, but verify their accuracy).
