Upgrade Your Ride: 139.7 To 114 Bolt Pattern Conversion Guide

Imagine you've just found the perfect set of wheels for your vehicle, but there's a catch - they have a different bolt pattern. Specifically, you're looking at upgrading from a 139.7mm (5.5 inches) bolt pattern to a 114.3mm (4.5 inches). This guide is your roadmap to navigating this conversion effectively. Whether you're a seasoned mechanic or a DIY enthusiast, we'll walk through everything you need to know to upgrade your ride with this bolt pattern conversion.

Understanding Bolt Patterns

Before we dive into the conversion process, it's important to understand what bolt patterns are:

• Bolt Pattern: This refers to the number of bolts and the diameter of an imaginary circle (in millimeters or inches) formed by the center of the lug nuts or studs on a wheel.

• Measurement: The 139.7mm or 114.3mm refers to the diameter of this circle, not the distance between the bolts.

Tools You'll Need

Here's a checklist of tools and supplies you'll need:

• Socket Set
• Torque Wrench
• Lug Wrench
• Wheel Spacers or Hub-centric Rings (optional but recommended)
• Jack and Jack Stands
• Measuring Tape
• Car Manual

Step-by-Step Conversion Process

Step 1: Confirm Compatibility

First, ensure that the wheels you plan to install will fit with your vehicle's hub and brakes:

• Hub Bore: Check if the wheel's hub bore matches or exceeds the vehicle's hub diameter. If not, use hub-centric rings.
• Offset: Ensure the wheel offset matches or is within an acceptable range for your vehicle.
• Backspacing: Compare the backspacing to avoid interference with suspension components.

Step 2: Prepare for Installation

• Raise the Vehicle: Use a jack to lift your car safely off the ground. Secure it with jack stands for stability.
• Remove Wheels: Carefully remove all lug nuts and take off the wheels.

Step 3: Wheel Spacers or Hub-Centric Rings

If your new wheels have a smaller hub bore:

• Wheel Spacers: These can adapt the bolt pattern and adjust the offset if necessary.
• Hub-Centric Rings: For ensuring the wheel is centered perfectly on the hub.

Step 4: Install New Wheels

• Mount the Wheel: Align the new wheel with the lug studs and gently push onto the hub. Ensure it sits flush.
• Secure Temporarily: Use a lug wrench or finger-tighten nuts to hold the wheel in place initially.

Step 5: Torque to Specifications

• Tighten in Sequence: Refer to your vehicle's torque specification chart. Tighten the lug nuts in a star or crisscross pattern to ensure even pressure.

Step 6: Double Check

• Check Clearance: Ensure there is no rubbing on the brakes, suspension, or chassis.
• Re-Torque: After driving a few miles, check and re-torque lug nuts to specifications, as they can settle.

<p class="pro-note">🔧 Pro Tip: Always double-check your vehicle's manual or manufacturer recommendations for exact torque specifications. Over or under-torqued lug nuts can lead to wheel failure.</p>

Common Mistakes to Avoid

• Wrong Wheel Spacers: Using spacers that aren't compatible or overcorrecting the bolt pattern.
• Misaligned Wheels: Not ensuring the wheel is perfectly centered can cause vibrations.
• Improper Torque: Incorrect tightening can lead to wheels coming loose or becoming excessively tight.

Helpful Tips & Advanced Techniques

• Measure Twice: Double-check your measurements before ordering any parts.
• Use a Torque Stick: Some mechanics prefer a torque stick for a more precise tightening.
• Professional Help: If unsure, consult with or employ a professional mechanic for this conversion.

<p class="pro-note">💡 Pro Tip: Consider keeping your old wheels as spares or selling them. The conversion often doesn't void the warranty, but always check with your manufacturer.</p>

Troubleshooting

• Vibrations: Check wheel balance, tire pressure, and alignment.
• Lug Nuts Coming Loose: Re-torque them after the first few miles, and inspect for signs of cross-threading.
• Rubbing Issues: Ensure enough clearance. Wheel spacers might help.

Wrapping Up

Performing a bolt pattern conversion from 139.7mm to 114.3mm can significantly change the look and performance of your vehicle. Remember to ensure compatibility, prepare your vehicle properly, and follow the correct installation procedures. Avoid common pitfalls by measuring twice, using the right tools, and perhaps consulting with professionals. This upgrade can not only enhance the aesthetic appeal of your car but can also offer better performance with the right set of wheels.
