How To Size Tires For A Jeep JL

When it comes to enhancing the performance and aesthetics of your Jeep Wrangler JL, upgrading to Jeep Wrangler 35 inch tires can make a world of difference. But before you take the plunge into the world of Jeep Wrangler big tires, it's essential to understand how to size them correctly for your Jeep JL.

One of the most popular choices among Jeep enthusiasts is fitting 35-inch tires on their Jeep Wrangler JL. These tires not only provide a more aggressive look but also offer improved off-road capability and ground clearance.

To ensure a proper fit, consider factors such as wheel size, suspension lift, and potential modifications. While some Jeep Wrangler JL models, such as the Rubicon, can accommodate 35-inch tires with minimal modifications, non-Rubicon models require at least 1.5 inches of lift to prevent rubbing or clearance issues.

What Size Jeep JL Tires Do You Need A Lift Kit For?

A common question among Jeep Wrangler JL owners is whether a lift kit is necessary when upgrading to bigger tires. While it's technically possible to fit Jeep Wrangler 35 inch tires on a stock Jeep JL Rubicon, a lift kit is often recommended to maximize clearance and maintain optimal performance both on and off the road.

The factory Jeep Wrangler JL tire size typically ranges from 29 to 33 inches, depending on the trim level and configuration. Upgrading to 35-inch tires will not only increase ground clearance but also improve off-road capability by providing better traction and stability over rugged terrain.

However, keep in mind that installing larger tires without a lift kit may result in rubbing against the fenders or suspension components, especially during articulation or full compression. To avoid potential issues and achieve the desired look and performance, consider investing in a compatible lift kit for your Jeep JL.

What To Be Aware Of When Increasing Jeep Tire Size

While upgrading to bigger tires can significantly enhance the appearance and performance of your Jeep Wrangler JL, there are several important factors to consider before making the switch.

First and foremost, be aware of potential clearance issues, especially if you're planning to install Jeep Wrangler 35 inch tires on a stock Jeep JL. Depending on the tire size and suspension setup, you may encounter rubbing against the fenders or suspension components, which can lead to damage and compromise safety.

Additionally, keep in mind that increasing tire size can affect other aspects of your Jeep's performance, including acceleration, braking, and fuel efficiency. Larger tires will result in an "effective" higher gear ratio, which can impact overall drivability and require recalibration of the speedometer and odometer.

Before upgrading to bigger tires, consult with a trusted mechanic or Jeep specialist to assess your specific needs and recommend appropriate modifications.

By taking the time to properly size and install your new tires, you can enjoy the benefits of enhanced off-road capability and head-turning aesthetics without sacrificing safety or performance.

How To Install Larger Tires On A Jeep Wrangler JL

Installing larger tires on your Jeep Wrangler JL can be a rewarding upgrade that enhances both its appearance and off-road capabilities. Here's a step-by-step guide on how to install larger tires:

Choose the Right Tires: Before purchasing new tires, ensure they are compatible with your Jeep Wrangler JL's specifications, including rim size, load rating, and intended use (e.g., off-road, highway).
Select Wheels: If you're upgrading to significantly larger tires, you may need to consider new wheels with a larger diameter and appropriate offset to accommodate the tires' size and prevent rubbing against the vehicle's components.
Measure Clearance: Before installation, measure the clearance between the current tires and the fenders, suspension components, and any other potential areas where the new tires may rub. This will help determine if any modifications, such as a lift kit or trimming, are necessary.
Install Lift Kit (If Needed): Depending on the size of the new tires and your Jeep Wrangler JL's suspension setup, you may need to install a lift kit to provide additional clearance. Follow the manufacturer's instructions carefully to ensure proper installation.
Mount Tires: Once the lift kit is installed (if required), mount the new tires onto the wheels using a tire mounting machine. Be sure to balance the tires properly to minimize vibrations and ensure a smooth ride.
Install Wheels and Tires: Carefully install the wheels and tires onto your Jeep Wrangler JL, ensuring they are securely fastened to the hub using the appropriate lug nuts. Use a torque wrench to tighten the lug nuts to the manufacturer's specifications.
Check Clearance: After installation, carefully inspect the clearance between the new tires and the vehicle's components. Turn the steering wheel lock-to-lock and compress the suspension to ensure there is no rubbing or interference.
Test Drive: Take your Jeep Wrangler JL for a test drive to ensure the new tires perform as expected. Pay attention to any unusual noises, vibrations, or handling issues that may indicate improper installation or fitment.
Final Adjustments: If necessary, make any final adjustments, such as adjusting tire pressure or making minor modifications to address rubbing or clearance issues.
Regular Maintenance: Once the larger tires are installed, be sure to maintain them properly by regularly checking tire pressure, rotating them at recommended intervals, and inspecting for signs of wear or damage.

By following these steps and ensuring proper installation, you can enjoy the benefits of larger tires on your Jeep Wrangler JL while maintaining optimal safety and performance on and off the road.
