Stock Honda Rubicon wheels, specifically for the Rubicon IRS models from 2015-2016, typically come in two primary dimensions: 12x6 and 12x7.5 inches. These specifications include not only the wheel's diameter and width but also crucial details like backspacing and bolt pattern, which are vital for proper fitment.
Understanding the exact size of your Honda Rubicon's stock wheels is essential for various reasons, from selecting appropriate replacement tires to considering aftermarket wheel upgrades. Wheel specifications are detailed measurements that ensure compatibility with your ATV's hub and suspension system.
Understanding Stock Wheel Specifications for Honda Rubicon IRS (2015-2016)
For the Honda Rubicon models equipped with Independent Rear Suspension (IRS) produced in 2015 and 2016, two distinct stock wheel sizes have been identified. These sizes encompass the wheel's physical dimensions and mounting specifications.
Here's a breakdown of the stock wheel sizes:
| Model | Year | Stock Wheel Size |
|---|---|---|
| Honda Rubicon IRS | 2015-2016 | 12x6 (5+1 offset, 4/110 bolt pattern, 10MM) |
| 12x7.5 (5.5+2 offset, 4/110 bolt pattern, 10MM) |
Decoding Wheel Measurements
To fully understand these specifications, it's helpful to break down what each part of the measurement signifies:
- Diameter and Width (e.g., 12x6 or 12x7.5): The first number (e.g., 12) indicates the wheel's diameter in inches, which determines the compatible tire bead size. The second number (e.g., 6 or 7.5) represents the wheel's overall width in inches.
- Offset/Backspacing (e.g., 5+1 or 5.5+2): This measurement describes how the wheel is positioned relative to the hub mounting surface. The two numbers usually indicate backspacing (distance from the inner lip to the mounting surface) and front spacing (distance from the outer lip to the mounting surface). For example, "5+1" means 5 inches of backspacing and 1 inch of front spacing, totaling a 6-inch-wide wheel. This significantly affects the vehicle's stance and tire clearance.
- Bolt Pattern (e.g., 4/110): This indicates the number of lug holes and the diameter of the circle they form, measured in millimeters. "4/110" means there are four lug holes arranged in a circle with a diameter of 110mm. This is critical for ensuring the wheel can bolt onto the ATV's hub.
- Additional Specifications (e.g., 10MM): This detail often refers to the diameter of the wheel studs or other specific mounting hardware requirements, ensuring a precise fit.
Why Knowing Your Stock Wheel Size Matters
Understanding your Honda Rubicon's stock wheel dimensions is beneficial for several reasons:
- Tire Replacement: It ensures you purchase tires that are correctly sized for your existing rims, guaranteeing safe and effective mounting.
- Aftermarket Upgrades: When considering new wheels for aesthetic appeal or performance enhancements, knowing the stock specifications helps you choose compatible aftermarket options that won't interfere with suspension components or fender wells.
- Vehicle Performance: Changes in wheel size, width, or offset can impact handling, steering feel, and overall stability. Sticking to or intelligently modifying stock specifications can help maintain optimal performance.
By referencing these specific measurements, owners of Honda Rubicon IRS models from 2015-2016 can confidently make informed decisions regarding their ATV's wheels and tires.
