If you own a Cadillac, knowing the proper lug nut size and torque specifications is important for changing a tire or swapping out those old steel wheels for a nice set of aftermarket alloys. Cadillac lug nuts come in a few different sizes depending on the model and year of your vehicle. Here’s a quick guide to Cadillac lug nut sizes so you can be prepared with the right tools.

What size are Cadillac Lug Nuts?

On most modern Cadillacs, the lug nuts are M14 x 1.5mm and M12 x 1.5mm.

Knowing the proper socket size is crucial so you don’t end up stripping or breaking a lug nut. It’s also wise to use a torque wrench to tighten the lug nuts to spec.

What Torque Spec are Cadillac Lug Nuts?

Along with the proper socket size, you’ll want to torque the Cadillac lug nuts to the factory specification to ensure the wheels are securely fastened. Overtightening can damage the studs or warp the rotors. Undertightening can allow the wheels to vibrate loose.

Here are the recommended Cadillac lug nut torque specs:

  • 12mm lug nuts – 140 ft-lbs

Always torque the lug nuts in a star pattern when installing wheels to ensure even pressure across the wheel hub.

Why Choose Aftermarket Cadillac Lug Nuts?

The factory Cadillac lug nuts get the job done, but aftermarket lug nuts can add style, security, and performance advantages. Custom lug nuts are available in a range of colors and designs to customize the look. Some feature a lock mechanism to deter theft. Others use tougher steel alloys to handle repeated changes without rounding off.

For example, the BONOSS Cadillac lug nuts are made of forged 50BV30 steel.

BONOSS uses advanced machining to manufacture lug nuts to exceed OEM standards. Their extensive testing ensures a perfect fit with no vibrations. The company also provides a 10-year warranty for peace of mind.

With the proper tools and specifications, changing a Cadillac tire or wheel is straightforward. Just be sure to use the right socket size – 22mm or 19mm depending on the lug nut size. Torque the nuts evenly in a cross pattern to spec. And consider upgrading to durable aftermarket lug nuts from a quality brand like BONOSS to get the most out of your Cadillac wheels. Knowing the proper lug nut size and torque goes a long way in keeping your ride secure.
