What size are GM lug nuts?
General Motors (GM) vehicles use a variety of lug nut sizes depending on the model and year. The most common lug nut sizes for GM vehicles are 1/2-inch, 9/16-inch, and 5/8-inch. Knowing the correct lug nut size is important for properly securing your vehicle's wheels and ensuring safe driving.
Determining Lug Nut Size
To find the lug nut size for your GM vehicle, you can check the owner's manual or look for a sticker inside the driver's side door jamb. This sticker will typically list the recommended tire size and lug nut size for your vehicle. You can also measure the lug nuts directly using a lug nut socket or caliper.
- 1/2-inch lug nuts are common on many GM trucks and SUVs, such as the Chevrolet Silverado, GMC Sierra, and Chevrolet Tahoe.
- 9/16-inch lug nuts are found on some GM sedans and crossovers, like the Chevrolet Malibu and Buick Enclave.
- 5/8-inch lug nuts are used on larger GM trucks and vans, including the Chevrolet Express and GMC Savana.
It's important to use the correct lug nut size for your vehicle to ensure a proper fit and secure the wheels safely. Using the wrong size lug nuts can lead to wheel separation and potentially cause an accident.
Lug Nut Torque Specifications
In addition to the lug nut size, it's also crucial to follow the recommended lug nut torque specifications for your GM vehicle. Overtightening or undertightening the lug nuts can cause problems, so be sure to consult your owner's manual or a trusted mechanic for the proper torque settings.
Properly maintaining your GM vehicle's lug nuts is an important safety consideration. By understanding the correct lug nut size and torque specifications, you can help ensure your wheels are securely attached and your driving experience is safe and reliable.

Is 7/8 the same as 22mm?
No, 7/87 / 87/8 inch is not exactly the same as $22$mm, but they are very close and often used interchangeably, as 7/87 / 87/8 inch is approximately $22.23$mm. The $22$mm measurement is slightly smaller than 7/87 / 87/8 inch, and using a 7/87 / 87/8 tool on a $22$mm fastener might be a bit loose, while using a $22$mm tool on a 7/87 / 87/8 fastener would be snug.
