If you own a Mazda CX5, knowing the proper lug nut size and torque specs is important for safe tire changes and wheel installations. Improperly torqued or wrong sized lug nuts can lead to a variety of problems, from wheels coming loose while driving to damaged wheel studs. In this guide, we’ll cover everything you need to know about Mazda CX5 lug nuts.

Quick Summary

  • Mazda CX5 lug nut size: M12 x 1.5
  • Mazda CX5 lug nut  torque spec: 108-147 Nm

Mazda CX5 Lug Nuts Size and Torque: A Complete Guide

What Size Are Mazda CX5 Lug Nuts?

All Mazda CX5 models use the same lug nut size and thread pitch. The factory lug nuts are:

  • Size – M12 x 1.5
  • Thread Pitch – 1.5mm
  • Hex Shape – 12mm hex

So if you need to replace your CX5 lug nuts or buy a set of aftermarket lug nuts, be sure to get the M12 x 1.5 size. Many brands offer this common size, though you’ll want to verify the thread pitch as well. Using the wrong thread pitch lug nut can damage the wheel studs.

What Torque Spec for Mazda CX5 Lug Nuts?

Along with the proper size, using the manufacturer recommended torque spec is critical when installing lug nuts. For the Mazda CX5, the factory torque spec for lug nuts is:

  • 108-147 Nm

This is the ideal torque range whether you are swapping wheels for seasonal tires, changing a flat, or doing any other wheel removal. It ensures the lug nuts are tightened enough to properly secure the wheels, while not overtightening which can damage the studs.

Always use a reliable torque wrench when tightening lug nuts to spec. An impact wrench should only be used to loosen or initially snug the nuts, then final tightening should be done with a torque wrench.

Over or under-torqued lug nuts are a common cause of wheel issues and should be avoided.
