Whether you’re looking to replace your stock wheels, upgrade to aftermarket rims, or simply learn more about wheel specifications, knowing the bolt pattern Cadillac CTS is crucial. This guide will cover everything from bolt pattern specifications, wheel sizes, compatibility, and tips for selecting the best wheels for your Cadillac CTS.
Understanding the Bolt Pattern Cadillac CTS
The bolt pattern Cadillac CTS refers to the number of lug nuts and the diameter of the circle they form. The correct bolt pattern ensures that the wheels fit securely and align properly with the wheel hub. If the bolt pattern is incorrect, the wheels won’t mount correctly, leading to instability and unsafe driving conditions.
Cadillac CTS Bolt Pattern by Model Year
The Cadillac CTS has undergone several changes since its introduction, but the bolt pattern has remained relatively consistent. Below is the bolt pattern information for different model years:
- 2003-2007 Cadillac CTS: 5x115mm
- 2008-2019 Cadillac CTS: 5x120mm
The shift from 5x115mm to 5x120mm happened in the second-generation Cadillac CTS (2008 and later). This means that wheels from the first generation are not directly interchangeable with later models without adapters.
What Does 5x115mm and 5x120mm Mean?
The 5x115mm and 5x120mm measurements refer to:
- Number of Lug Holes: 5
- Diameter of the Bolt Circle: 115mm or 120mm
For example, a 5x120mm bolt pattern means there are five lug holes arranged in a 120mm diameter circle.
Center Bore and Lug Nut Specifications for Cadillac CTS
In addition to the bolt pattern Cadillac CTS, you must consider the center bore and lug nut specifications:
- Center Bore: 66.9mm (for most CTS models)
- Lug Nut Thread Size: M14x1.5
- Recommended Lug Nut Torque: 100-140 lb-ft
Ensuring that the wheels you purchase match these specifications prevents fitment issues and enhances safety.

Choosing the Right Wheels for Your Cadillac CTS

For example, if you own a 2003-2007 CTS (5x115mm) but want to install 5x120mm wheels, you will need an adapter to make them fit properly. However, using adapters can impact handling, so it’s best to get wheels that naturally fit your vehicle’s specifications.
