Installing a 4-inch lift on your Wrangler Rubicon can significantly enhance its off-road capabilities and overall appearance. However, one of the most crucial aspects of this modification is understanding tire fitment post-regear. Choosing the right tires ensures that your vehicle performs optimally and maintains its aesthetic appeal.
Understanding Tire Fitment
Tire fitment refers to the compatibility of tires with your vehicle after modifications. When you lift your Wrangler Rubicon, the increase in height can affect the size of tires you can install without causing issues such as rubbing or clearance problems.
Factors to Consider for Tire Fitment
- Tire Diameter: The overall diameter of the tire is crucial. A larger diameter can provide better ground clearance but may lead to rubbing against the fenders.
- Tire Width: Wider tires offer better traction but can also cause clearance issues.
- Backspacing and Offset: These measurements affect how the tire sits in relation to the wheel well. Proper backspacing ensures that the tires do not stick out too far or sit too close to the suspension components.
- Wheel Size: The size of your wheels can impact the type of tires you can use. Ensure that the wheel size is compatible with the tires you choose.
Recommended Tire Sizes for a 4-Inch Lift
After installing a 4-inch lift on your Wrangler Rubicon, the following tire sizes are generally recommended:
- 33-inch tires: A popular choice that provides a good balance between performance and aesthetics.
- 35-inch tires: Offers increased ground clearance and off-road capability, but may require additional modifications.
- 37-inch tires: Best for extreme off-roading, but be aware of potential rubbing and the need for further adjustments.
Common Tire Options for Wrangler Rubicon
When selecting tires for your lifted Wrangler Rubicon, consider the following popular options:
- BFGoodrich All-Terrain T/A KO2: Known for its durability and performance both on and off-road.
- Goodyear Wrangler MT/R with Kevlar: Excellent for extreme off-road conditions, providing superior traction.
- Falken Wildpeak A/T3W: Offers a great balance of on-road comfort and off-road capability.
- Nitto Ridge Grappler: A hybrid tire that performs well in various terrains.
Installation Considerations
When installing larger tires, consider the following installation aspects:
- Wheel Alignment: After installation, a proper alignment is crucial to ensure even tire wear and optimal handling.
- Suspension Adjustments: Depending on the tire size, you may need to make additional suspension adjustments to avoid rubbing.
- Brake Line Extensions: Larger tires can affect brake lines, so consider extensions if necessary.
Testing Tire Fitment
After installing your new tires, it’s essential to test fitment by performing the following:
- Full Lock Turn Test: Turn the steering wheel fully in both directions to check for rubbing.
- Flex Test: Drive over uneven terrain to see how the tires perform under flexing conditions.
- Visual Inspection: Regularly check for signs of rubbing or wear on the tires and wheel wells.
Conclusion
Choosing the right tire size after installing a 4-inch lift on your Wrangler Rubicon is essential for maximizing performance and maintaining safety. By considering tire diameter, width, backspacing, and offset, you can select tires that fit well and enhance your vehicle’s capabilities.
Always consult with a professional if you have any doubts about tire fitment or installation to ensure that your modifications are safe and effective.
