Introduction

This tutorial guides you through the process of fitting 18x9 +10 and 18x10 +10 Work CR2P wheels on a G37 sedan. The wheel specifications discussed will help you understand how to achieve an optimal fitment, including tire sizes and considerations for a square setup. This guide is perfect for car enthusiasts looking to enhance their vehicle's aesthetics and performance.

Step 1: Understanding Wheel Specifications

Before purchasing or installing wheels, it’s essential to comprehend the specifications:

  • Wheel Width: 18x9 and 18x10 denote the width of the wheels in inches.
  • Offset: A +10 offset means that the mounting surface of the wheel is 10 mm in front of the centerline, impacting how the wheel sits in relation to the fender.
  • Tire Sizes:
    • For 18x9 wheels: Use 235/40 tires.
    • For 18x10 wheels: Use 265/35 tires.

Practical Tips

  • Ensure your vehicle can accommodate these widths and offsets for proper clearance.
  • Consider the driving conditions and your style—wider tires provide better grip but can impact ride comfort.

Step 2: Preparing for Installation

Gather the following tools and equipment:

  • Lug wrench
  • Jack and jack stands
  • Torque wrench
  • Tire pressure gauge

Installation Steps

  1. Lift the Vehicle:

    • Use the jack to lift your G37 sedan safely.
    • Secure the vehicle with jack stands.
  2. Remove Existing Wheels:

    • Loosen the lug nuts using a lug wrench.
    • Remove the lug nuts completely and take off the existing wheels.

Step 3: Test Fitting the Wheels

Test fitting ensures that the new wheels will fit without any issues:

  1. Install One Wheel at a Time:

    • Place the 18x9 +10 wheel on one front corner.
    • Hand-tighten the lug nuts to hold the wheel in place.
  2. Check for Clearance:

    • Inspect the wheel’s fitment against the fender and suspension components.
    • Ensure there is enough space to avoid rubbing when turning or going over bumps.
  3. Repeat for the Rear:

    • Repeat the test fit with the 18x10 +10 wheel on the rear side.
    • Again, check for clearance and potential rubbing.

Common Pitfalls

  • Not checking for brake caliper clearance can lead to issues.
  • Ensure the tire pressure is correct before fitting.

Step 4: Final Installation

Once satisfied with the fitment:

  1. Tighten Lug Nuts:

    • Use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.
    • Follow a criss-cross pattern to ensure even tightening.
  2. Lower the Vehicle:

    • Carefully lower the vehicle back to the ground.
    • Perform a final check on the lug nut tightness after the car is on the ground.

Conclusion

You've successfully fitted 18x9 and 18x10 Work CR2P wheels on your G37 sedan. Key takeaways include understanding wheel specifications, ensuring proper clearance during test fitting, and following safe installation practices. For the next steps, consider aligning your wheels or adjusting suspension settings to optimize handling. Enjoy your new wheel setup!
