The TJ Wrangler is a popular choice among off-road enthusiasts, especially for those who love tackling extreme trails. One of the key modifications many TJ owners consider is upgrading to 35-inch tires. This article will explore how to maximize 35-inch tire fitment on your TJ Wrangler, ensuring both performance and reliability on challenging terrains.
Understanding Tire Fitment
Tire fitment is crucial for any off-road vehicle. It affects not only the vehicle’s performance but also its safety and reliability. When upgrading to 35-inch tires on a TJ Wrangler, several factors come into play.
- Wheel Well Clearance
- Suspension Modifications
- Gear Ratios
- Steering Components
Wheel Well Clearance
Before installing 35-inch tires, it’s essential to assess the wheel well clearance. The TJ Wrangler’s stock setup may not provide enough space for larger tires without modifications.
Measuring Clearance
To ensure proper fitment, measure the following:
- Front and rear wheel wells
- Distance from the axle to the fender
- Suspension travel
Suspension Modifications
Upgrading the suspension is often necessary when fitting larger tires. A lift kit can provide the additional height needed for 35-inch tires.
Types of Lift Kits
Consider the following types of lift kits:
- Budget Boost Kits
- Coil Spring Lift Kits
- Long Arm Lift Kits
Gear Ratios
When upgrading to larger tires, adjusting the gear ratios is essential to maintain optimal performance. Larger tires can affect acceleration and fuel economy if the gear ratios are not adjusted accordingly.
Recommended Gear Ratios
For 35-inch tires, the following gear ratios are recommended:
- 4.10:1 for automatic transmissions
- 4.56:1 for manual transmissions
- 4.88:1 for heavy off-road use
Steering Components
Upgrading to 35-inch tires can put additional strain on the steering components of the TJ Wrangler. It’s crucial to ensure that the steering system can handle the increased size and weight of the larger tires.
Upgrading Steering Components
Consider upgrading the following components:
- Steering stabilizer
- High-performance tie rod
- Adjustable track bar
Alignment and Tire Pressure
After installing larger tires and making necessary modifications, proper alignment and tire pressure are crucial for performance and safety.
Importance of Alignment
Proper alignment ensures that the vehicle handles well and that the tires wear evenly. It’s advisable to have a professional alignment done after any modifications.
Tire Pressure Recommendations
Maintaining the correct tire pressure is vital for performance. The recommended tire pressure for 35-inch tires on a TJ Wrangler is typically between 30-35 PSI, but this can vary based on usage.
Testing and Trail Performance
Once all modifications are complete, it’s time to test your TJ Wrangler on the trails. Pay attention to how the vehicle handles and performs in various conditions.
Trail Challenges to Consider
When testing your vehicle, consider the following trail challenges:
- Rock crawling
- Mud pits
- Steep inclines
Conclusion
Maximizing 35-inch tire fitment on a TJ Wrangler requires careful planning and execution. By considering wheel well clearance, suspension modifications, gear ratios, and steering components, you can enhance your vehicle’s performance and reliability on extreme trails. Always remember to test your setup in a safe environment before tackling more challenging terrains.
