Finding the right wheels for your vehicle can feel like navigating a minefield of numbers and specifications. Understanding the seemingly cryptic "5x120 17 inch wheels" is key to a successful and safe upgrade. This guide will demystify this code, helping you confidently choose the perfect fit for your car.
What Does 5x120 Mean?
The "5x120" part of the specification refers to the bolt pattern of your wheel. Let's break it down:
- 5: This indicates the number of lug nuts or studs on your wheel. Most passenger vehicles use either 4 or 5 lug nuts.
- 120: This represents the pitch circle diameter (PCD), measured in millimeters. It's the diameter of the imaginary circle that passes through the centers of all five lug holes. This measurement is crucial; using the wrong PCD will prevent the wheel from mounting correctly.
Important: Incorrect bolt patterns can lead to dangerous and potentially catastrophic wheel failure. Always double-check your vehicle's specifications before purchasing any wheels. Your owner's manual or a reliable online database specific to your vehicle's make, model, and year are excellent resources.
Understanding the 17 Inch
The "17 inch" refers to the wheel diameter, measured from one edge of the rim to the opposite edge. This is a visual measurement and significantly impacts the overall look and feel of your vehicle. Larger diameter wheels often pair with lower-profile tires, altering handling and ride comfort.
Choosing the right wheel diameter involves considering:
- Tire Size: The 17-inch wheel diameter dictates the tire size you can safely and effectively use. Again, consult your owner's manual or a tire size calculator to ensure compatibility.
- Vehicle Compatibility: Certain vehicles may have limitations on the maximum wheel diameter they can accommodate due to suspension components, brake calipers, or other factors.
Beyond the Basics: Essential Wheel Specifications
While 5x120 and 17 inches are fundamental, several other factors are equally important when selecting wheels:
Offset:
This measurement specifies the distance between the wheel's mounting surface and its centerline. Positive offset pushes the wheel further outward, while negative offset pulls it inward. The correct offset is critical for proper wheel fitment and suspension geometry.
Wheel Width:
Measured in inches, the width of the wheel affects tire fitment and handling characteristics. A wider wheel generally allows for a wider tire, enhancing grip and stability, but it may also affect turning radius and potentially rub against suspension or body components.
Backspacing:
This relates to the distance between the mounting surface and the back of the wheel. Backspacing, along with offset, directly influences how the wheel sits within the wheel well.
Hub Bore:
This is the diameter of the central hole in the wheel, which fits over the vehicle's hub. Incorrect hub bore size can lead to wheel wobble and potential safety hazards.
Finding the Right 5x120 17 Inch Wheels
With a thorough understanding of these specifications, you can confidently search for 5x120 17-inch wheels that perfectly match your vehicle and desired aesthetic. Remember to always prioritize safety and compatibility. Consult a tire and wheel professional if you have any doubts or require assistance with your selection. Don't let the numbers intimidate you – informed decision-making leads to a safer and more satisfying upgrade.
