The Wrangler is built for adventure, and its wheels are the point of contact between you and the trail. Whether you’re looking to tackle challenging terrain, improve on-road comfort, or simply give your Wrangler a more aggressive stance, understanding wheel specifications is key.
This guide will walk you through everything you need to know, from bolt patterns and offsets to material types and common sizes, ensuring you make an informed choice for your 2017 model.
The 2017 Jeep Wrangler, often referred to by its JK generation codename, came with a specific set of factory wheel specifications. However, the aftermarket offers a vast array of options.
These wheels are not just about looks; they can significantly affect your Jeep's handling, fuel efficiency, and its ability to withstand the rigors of off-roading.
Selecting wheels involves a deep dive into technical details that might seem daunting at first, but understanding them will empower you to choose wisely. We’ll break down these technicalities into easy-to-understand concepts, focusing on what truly matters for a 2017 Wrangler owner.
Understanding Wheel Specifications For Your 2017 Jeep Wrangler
Before diving into specific wheel options, it’s essential to grasp the fundamental specifications that define a wheel’s fitment and function on your 2017 Jeep Wrangler. These parameters ensure compatibility and optimize performance for your specific needs.
Bolt Pattern: The Foundation Of Fitment
The bolt pattern, also known as the lug pattern, is the arrangement of the wheel studs on your Jeep’s hub. For the 2017 Jeep Wrangler (JK), the standard bolt pattern is 5×5 inches (or 5x127mm). This means there are five lug nuts, and the diameter of the circle they form is five inches. This is a critical measurement; wheels with a different bolt pattern will not fit your vehicle. Always double-check this specification before purchasing any new wheels.
Center Bore: The Hub’s Embrace
The center bore is the hole in the center of the wheel that fits over your Jeep’s hub. While the bolt pattern dictates how the wheel attaches, the center bore ensures it sits flush and centered on the axle. A wheel with a larger center bore than the hub can be used, but it requires hub-centric rings to properly center the wheel and prevent vibration. The 2017 Wrangler’s center bore is 71.5mm. Using wheels with a correctly sized center bore, or the appropriate hub-centric rings, is vital for a smooth ride and to avoid unnecessary stress on your wheel bearings.
Offset: Steering The Wheel’s Position
Wheel offset refers to the distance between the wheel’s mounting surface (where it meets the hub) and the centerline of the wheel. It’s measured in millimeters (mm) and can be positive, negative, or zero.
- Zero offset: The mounting surface is exactly at the wheel’s centerline.
- Positive offset: The mounting surface is positioned outboard of the centerline. This pushes the wheel further *into* the fender.
- Negative offset: The mounting surface is positioned inboard of the centerline. This pushes the wheel further *out* from the fender.
The 2017 Jeep Wrangler typically comes with a +44.5mm factory offset. Many aftermarket wheels offer a lower or negative offset to achieve a more aggressive stance and allow for larger tires. However, significantly changing the offset can affect steering geometry, suspension wear, and may require fender modifications or larger tires to prevent rubbing.
Backspacing: Another Measure Of Wheel Depth
Backspacing is similar to offset but is measured from the wheel’s mounting surface to the *back* of the wheel rim. It’s also measured in inches or millimeters. A lower backspacing value means the wheel sits further out from the hub, similar to a negative offset. For the 2017 Wrangler, the factory wheels have approximately 5.2 inches of backspacing. Understanding backspacing is crucial when fitting larger tires, as it directly impacts clearance with suspension components and fenders.
Wheel Diameter And Width: Size Matters
Wheel diameter refers to the overall size of the wheel from one edge to the other, usually measured in inches. Common diameters for the 2017 Wrangler range from 15 inches (often for dedicated off-roading) up to 20 inches or more for street-focused builds.
Wheel width, also measured in inches, determines how much tire can be mounted on the wheel. Wider wheels generally accommodate wider tires. The factory width for a 2017 Wrangler is typically 7.5 inches. Aftermarket options can range from 8 inches to 10 inches or even wider, depending on the tire size and intended use.
Material Types: Strength And Weight Considerations
The material used to construct a wheel significantly influences its strength, weight, and cost. For the 2017 Jeep Wrangler, you’ll primarily encounter two main types:
1. Alloy Wheels

Key Considerations For Your 2017 Wrangler Build
When selecting wheels for your 2017 Jeep Wrangler, several factors beyond basic fitment come into play.
1. Tire Size And Clearance
The wheels you choose must accommodate the tires you intend to run. Larger tires (e.
g. , 33-inch, 35-inch, 37-inch, or larger) often require wheels with specific offsets and backspacing to ensure they don't rub against fenders, suspension components, or the frame.
- Pro Tip: Always check the maximum tire size recommended for a specific wheel width and offset. A common setup for a 2017 Wrangler is a 17×9 wheel with a -12mm offset, paired with a 35-inch tire. This combination provides a wide stance and ample room for larger tires, though fender flares or a lift kit might be necessary.
2. Lift Kit And Suspension
If you plan to install a lift kit, this will significantly alter your Wrangler’s stance and tire clearance. Taller lifts allow for larger tires, and the choice of wheels becomes even more critical to maximize the benefit of the lift. The type of suspension (e.g., coil springs, leaf springs, though Wranglers use coil springs) can also influence clearance.
3. Intended Use: On-road Vs. Off-road
- Primarily Off-Road: Opt for durable steel wheels or strong, impact-resistant alloy wheels. Smaller diameter wheels (15-inch or 17-inch) with taller tire sidewalls are preferred for better flex, cushioning, and protection against trail hazards. A more negative offset can widen the stance for stability.
- Primarily On-Road: Larger diameter wheels (17-inch, 18-inch, or 20-inch) with lower-profile tires can enhance on-road handling and aesthetics. Alloy wheels are common here for their style.
- Mixed Use: A 17-inch wheel is often the best compromise, offering a good balance for both daily driving and weekend off-road adventures.
4. Weight And Unsprung Mass
Unsprung mass refers to the weight of components not supported by the suspension, like wheels, tires, brakes, and hubs. Increasing unsprung mass (with heavier wheels and tires) can negatively impact:
- Handling: Makes the suspension work harder, potentially leading to a choppier ride.
- Acceleration and Braking: Requires more energy to get moving and stop.
- Fuel Economy: More weight to move means more fuel burned.
- Component Wear: Puts extra strain on axles, bearings, and suspension components.
Choosing lighter alloy wheels can help mitigate these effects.
5. Aesthetics And Style
While performance and fitment are paramount, the look of your Wrangler is also important. Wheels come in countless styles, finishes (matte black, polished, chrome, machined), and designs.
Consider how the wheels will complement your Jeep's overall appearance, paint color, and any other modifications.
