2010-2012 i SV, i Sport, i Touring, i Grand Touring 12mm x 1.5
2010-2012 s Touring, s Grand Touring 14mm x 1.5

Lug Nut Torque Specifications for Different Generations

In addition to knowing the lug nut size, it is equally important to tighten the lug nuts to the correct torque specifications. Proper torque ensures that the lug nuts are securely fastened without being over-tightened or under-tightened. Here are the lug nut torque specifications for different generations of the Mazda CX 7:

Generation Torque Specifications (ft/lbs) Torque Specifications (Nm)
First Generation (2007-2012) 85-105 ft/lbs 115-142 Nm
Second Generation (2010-2012) 85-105 ft/lbs 115-142 Nm

It is crucial to follow the recommended torque specifications to ensure the proper installation and secure fastening of the lug nuts. Over-tightening can lead to damaged threads or even breakage, while under-tightening can result in loose wheels and potential safety hazards.

Remember to use a torque wrench to achieve the specified torque values accurately. It is also advisable to recheck the lug nut torque after driving a short distance, as the initial tightening may settle due to wheel movement.
