1. Check your owner's manual: The owner's manual should specify the bolt pattern (often expressed as PCD - Pitch Circle Diameter) and lug nut size.
2. Look at the wheel itself: The bolt pattern is visible when you look at the wheel's mounting surface. Count the number of lug nuts and measure the distance between opposite lug nuts. This measurement is the diameter of the bolt circle. However, accurately measuring this requires precision tools, so this is less reliable than other options.
3. Use a vehicle specification website: Websites like Edmunds, Car and Driver, or others dedicated to vehicle specifications, will list this information for many vehicle years and models. Search for "1992 Camaro RS specifications."
4. Consult a parts store or mechanic: Auto parts stores (like AutoZone, Advance Auto Parts, etc.) often have resources to look up this information based on the vehicle's year, make, and model. A mechanic will certainly know.
5. Check the wheel hub: While a bit more involved, removing a wheel (carefully!) reveals the hub, which will have the bolt pattern clearly visible. Caution: Ensure the vehicle is properly secured before removing a wheel.
The most reliable methods are checking the owner's manual or a reputable vehicle specification website. Avoid relying solely on measuring the wheel unless you have the proper equipment and expertise.
