Preparing for the Installation
Preparation is key to a successful tire installation. Follow these steps to get ready:
- Gather Tools: You will need basic tools such as a jack, jack stands, lug wrench, and a tire pressure gauge.
- Check Local Regulations: Ensure that fitting larger tires complies with local laws and regulations regarding vehicle modifications.
- Inspect Current Setup: Check your current tires, wheels, and suspension components for wear and tear.
Choosing the Right Tires
When selecting 37-inch tires for your JL Wrangler, consider the following factors:

- Load Rating: Ensure the tires can handle the weight of your vehicle and any additional gear you may carry.
- Brand Reputation: Opt for reputable brands known for durability and performance in off-road conditions.
Installation Process
Now that you are prepared, follow these steps to install your new 37-inch tires:

- Tighten Lug Nuts: Use the lug wrench to securely tighten the lug nuts in a star pattern to ensure even pressure.
- Check Clearance: Lower the vehicle and inspect the clearance between the tires and suspension components.
Post-Installation Adjustments
After installing your 37-inch tires, there are a few adjustments you may need to make:
- Alignment: Have a professional perform a wheel alignment to ensure proper handling and tire wear.
- Recalibrate Speedometer: Larger tires can affect your speedometer reading; recalibration may be necessary.
