Choosing the right tire and wheel combination is crucial for any off-road vehicle, and the pairing of 35" tires with 17" wheels is a popular choice among enthusiasts. This guide delves into the specifics of this setup, exploring its advantages, disadvantages, and considerations for fitment and performance.
Why Choose 35" Tires with 17" Wheels?
The combination of 35" tires and 17" wheels offers a compelling balance between aggressive off-road capability and relative affordability. Let's break down the reasons behind its popularity:
- Aggressive Tread Patterns: 35" tires typically boast aggressive tread patterns designed for superior traction in mud, sand, rocks, and snow. This increased surface area significantly improves grip compared to smaller tires.
- Increased Ground Clearance: The larger diameter directly translates to greater ground clearance, enabling you to tackle more challenging terrains with confidence. This is particularly beneficial when negotiating obstacles and avoiding damage to the undercarriage.
- Improved Approach and Departure Angles: Taller tires contribute to improved approach and departure angles, further enhancing off-road capabilities, allowing you to climb steeper inclines and descend more challenging slopes.
- Availability and Cost: Compared to larger wheel diameters (like 18" or 20"), 17" wheels are generally more widely available and often less expensive, making them a more budget-friendly option for building a capable off-road rig.
- Wider Range of Tire Options: 17" wheels offer a broader selection of 35" tires from various manufacturers, providing more choices based on specific needs and driving styles.
What are the Disadvantages of 35" Tires with 17" Wheels?
While offering many advantages, this combination isn't without its drawbacks:
- Increased Rotating Mass: Larger, heavier tires increase the rotational inertia of your wheels, potentially impacting acceleration and braking performance. This can also put extra strain on your vehicle's drivetrain components.
- Potential for Rubbing: Fitting 35" tires may require modifications such as lift kits, wheel spacers, or fender trimming to prevent rubbing against the body or suspension components. This is dependent on your specific vehicle and lift height.
- Higher Speedometer Error: Larger tires will cause your speedometer to read slower than your actual speed. This discrepancy is significant enough to warrant recalibration or consideration for the error.
- Increased Fuel Consumption: The added rolling resistance from larger, heavier tires will result in decreased fuel economy.
- Gear Ratio Considerations: For optimal performance, you may need to consider adjusting your gear ratios to compensate for the larger tires, ensuring your engine can maintain sufficient power and torque across the RPM range.
What about Backspacing and Offset?
Backspacing and offset are crucial factors in determining wheel fitment. Incorrect backspacing can cause the tires to rub against the suspension or body, even with a lift kit. Similarly, offset affects the wheel's position relative to the hub, impacting scrub radius and potential rubbing. Thorough research and potentially consultation with a tire professional are necessary to ensure proper fitment for your specific vehicle.
What lift height do I need for 35" tires?
The required lift height varies greatly depending on the vehicle. Some vehicles might require a 4-inch lift or more, while others might need as little as 2 inches. Always consult a lift kit manufacturer's instructions and specifications to ensure proper clearance. Failure to do so could result in serious damage to your vehicle.
Are there any other things to consider?
Yes, several other aspects should be considered:
- Your vehicle's specifications: Be sure to carefully check the vehicle's specifications and consult the owner's manual to understand the limits of the vehicle's suspension and drivetrain components.
- Cost of installation: Installing 35" tires and the potentially necessary lift kit and other modifications can be expensive.
- Legal Considerations: Be sure to comply with local regulations regarding tire size and modifications to your vehicle.
Conclusion
The 35" tire with 17" wheel combination offers substantial benefits for off-road performance, but it's essential to carefully consider the potential drawbacks and ensure proper fitment. Thorough research, precise measurements, and potentially professional guidance will help you make an informed decision and safely enjoy the enhanced off-road capabilities this setup provides. Remember that proper planning and understanding are vital to avoid costly mistakes.
