Just for fun... When Deepseek AI as asked the best tire size for a JT that has a 2" lift, it responded:
When choosing the best tire size for a Jeep Gladiator with a 2" lift, you want to balance increased off-road capability with maintaining proper clearance, handling, and drivetrain performance. A 2" lift allows you to run larger tires than stock, but you still need to consider factors like rubbing, gearing, and overall vehicle dynamics.
### Recommended Tire Sizes for a Jeep Gladiator with a 2" Lift:
1. **35x12.50R17** (or 315/70R17):
- **Why it's popular**: This is the most common and recommended tire size for a Gladiator with a 2" lift. It provides a significant improvement in off-road capability without requiring major modifications.
- **Fitment**: Fits well with minimal to no rubbing, especially with proper wheel offset (around +18 to -12mm). May require minor adjustments like adjusting the steering stop or trimming the fender liners.
- **Performance**: Maintains decent on-road manners and doesn't overly stress the drivetrain, though regearing may be beneficial if you frequently drive in hilly or mountainous areas.
2. **285/75R17** (approximately 34x11.2R17):
- **Why it's good**: Slightly narrower than a 35-inch tire, this size offers a good balance of off-road performance and on-road comfort. It’s a great option if you want a less aggressive setup.
- **Fitment**: Fits easily with a 2" lift and typically doesn’t require any trimming or adjustments.
- **Performance**: Lighter than 35-inch tires, so it has less impact on acceleration, braking, and fuel economy.
3. **37x12.50R17**:
- **Why it's an option**: If you want a more aggressive look and maximum off-road capability, 37-inch tires are possible with a 2" lift, but they require more modifications.
- **Fitment**: May require additional modifications like aftermarket fenders, bump stops, and possibly a wheel with the correct offset to avoid rubbing. You may also need to regear the axles to maintain performance.
- **Performance**: 37-inch tires will impact acceleration, braking, and fuel economy more significantly. Regearing to 4.56 or 4.88 is highly recommended for optimal performance.
4. **33x12.50R17** (or 285/70R17):
- **Why it's good**: If you’re looking for a more conservative upgrade, 33-inch tires are a great option. They provide better off-road performance than stock tires without requiring a lift, but they pair well with a 2" lift for added clearance.
- **Fitment**: Fits easily with no modifications.
- **Performance**: Minimal impact on drivetrain and fuel economy, making it a practical choice for daily driving.
### Key Considerations:
- **Wheel Offset**: Proper wheel offset is crucial to avoid rubbing. A wheel with an offset of +18 to -12mm is ideal for 35-inch tires.
- **Regearing**: If you go with 35-inch or larger tires, consider regearing your axles (especially if you have the factory 4.10 gears) to restore performance and reduce strain on the drivetrain.
- **Fender Clearance**: Depending on the tire size and wheel offset, you may need to trim fender liners or add aftermarket fenders for clearance.
- **Bump Stops**: Extending bump stops may be necessary to prevent the tires from contacting the fenders during articulation.
### Best Overall Choice:
For most Jeep Gladiator owners with a 2" lift, **35x12.50R17** (or 315/70R17) is the best tire size. It offers a significant improvement in off-road capability, fits well with minimal modifications, and maintains decent on-road performance. If you want a more aggressive setup and are willing to make additional modifications, **37x12.50R17** is an option, but it comes with trade-offs in drivetrain strain and fuel economy.
Always consult with a professional or experienced off-road shop to ensure proper fitment and performance for your specific setup.
