Understanding Tire Lift Requirements for 35 Inch Off-Road Tires

When considering the installation of large 35-inch tires on your vehicle, one of the most critical factors is the lift required to properly clear both the wheels and the vehicle's body. This article will guide you through the process of determining the necessary lift for your specific vehicle model and will help you understand the options available to accommodate these massive tires.

Factors Influencing the Required Lift

The amount of lift needed for 35-inch tires can vary greatly depending on the vehicle model and its stock height. Several key factors to consider include:

The specific make and model of the vehicle, including the year and trim level. The stock ride height of the vehicle. The clearance needed between the tires and the vehicle's body, especially the fenders and wheel wells. The intended use of the vehicle, whether it will predominantly be on-road, off-road, or a mix of both.

For older models like the 1990s Jeep Cherokee, a lift of 5 to 6 inches is often necessary. However, newer models like the Jeep Wrangler might require only 3 inches of lift, depending on the specific trim level and suspension setup. The Fitment Combos section of the vehicle’s manual will provide insights into the maximum tire size that can be accommodated without a lift.

Important Considerations Before Installation

Before committing to a lift kit and large tires, it is essential to conduct a few crucial checks:

Inspect the fender/wheel wells to ensure there is adequate clearance for 35-inch tires. If tires are grinding against the wheel wells, additional lift or modifications may be necessary. Consider whether you are willing to roll your fender guards or modify the fender/body materials to accommodate the larger tires. This is a more permanent and potentially less costly alternative to a full lift.

Minimal Lift Kits for 35 Inch Tires

For those looking to achieve a sufficient lift with minimal fuss, a 2.5-inch lift kit is highly recommended. This provides a balance between clearance for the tires and maintaining a relatively low profile. A 2.5-inch lift combined with 35-inch tires can offer excellent performance in both on-road and off-road conditions.

Technically, a 2.5-inch lift kit alone might not provide enough clearance for some 35-inch tires on certain vehicles, especially if the vehicle has limited stock ride height. For a more substantial lift, consider a 3.5-inch lift kit. This would be ideal for achieving proper tire clearance and articulation, especially when going off-road. However, for some newer Wranglers, a 3-inch lift might be sufficient, providing enough space for the tires without the need for extreme modifications.

Spacers vs. Lift Kits

It is often preferable to use a lift kit rather than spacers. Spacers are not considered an effective or safe long-term solution for tire installation, as they can cause issues with alignment, ride quality, and overall structural integrity of the vehicle. Lift kits, on the other hand, provide a more balanced and secure fit, ensuring better performance and longevity.

For those who want to go the extra mile, using a 6-inch lift kit can virtually eliminate any rubbing against the wheel wells. However, this level of lift is more extreme and may not be necessary for all vehicles. It is also worth noting that many manufacturers provide a standard 2.5-inch lift kit, which is quite common and adequate for most scenarios.

Regearing for 35 Inch Tires

The decision to install 35-inch tires should not be made without also considering the impact on vehicle gearing. 35-inch tires are significantly larger in diameter than stock tires, which means they rotate more slowly but cover more distance. This difference in diameter can affect the gearing ratio, affecting performance and fuel efficiency.

To maintain the proper gearing ratio, you may need to regear your differentials. This process involves replacing the gears to ensure that the vehicle still performs optimally. It is essential to conduct thorough research before purchasing new tires to understand the potential impact on your vehicle's overall performance and to determine the appropriate gearing required.

In conclusion, the amount of lift required for 35-inch tires can vary widely depending on the specific vehicle. While a 2.5-inch lift kit provides a balanced solution for many, a 3.5-inch lift kit is often necessary for proper articulation and tire clearance, especially for off-road use. Always prioritize safety and performance over extreme modifications, and consider the long-term impact on vehicle maintenance and performance. For the best advice, consult a professional mechanic or a reputable lift kit supplier.
