When upgrading your GMC Sierra with a 2-inch leveling kit, finding the right tire size is essential to enhance performance. A leveling kit gives your truck the ability to accommodate larger tires while maintaining proper clearance and safety.
This article will explore all the factors you need to consider to determine what size tire for GMC Sierra with 2 inch leveling kit works best.
What Size Tire for GMC Sierra with 2 Inch Leveling Kit?
1. Upper Body Clearance and Tire Width
The leveling kit increases clearance between the upper body and the tires, allowing for wider and taller options. However, selecting a tire width that does not protrude from the wheel well is crucial for legality and performance.
Common choices include 275 mm to 305 mm, depending on rim width and offset. If you’re wondering what size tire for GMC Sierra with 2 inch leveling kit, sizes like 275/60R20 or 285/55R20 are popular for providing an excellent fit.
2. Mud Guard and Front Clearance
A 2-inch leveling kit ensures more space between the tires and mud guards, reducing the risk of contact during turns or when driving on uneven terrain. For a balanced setup, sizes like 33×12.5R20 or 285/60R20 fit well, ensuring smooth operation without unnecessary modifications.
3. Upper Control Arm and Tire Space
Choosing the right tire size also involves maintaining sufficient space between the tire and the upper control arm. Tires that are too wide, such as those exceeding 305 mm, can cause rubbing and reduce maneuverability. Ensuring at least a 1-inch clearance will keep your GMC Sierra running efficiently.
4. Rubbing on the Front and Rear When Turning
Larger tires can lead to rubbing against fenders or suspension components during sharp turns. This issue is particularly common with oversized tires on narrow rims. When deciding what size tire for GMC Sierra with 2 inch leveling kit, ensure the tire width and aspect ratio work with your truck’s geometry.
5. Fender Rolling and Fender Liners
If you opt for the maximum possible tire size, you might need to roll the fenders or adjust the fender liners to prevent rubbing. While this is not necessary for most tires like 275/60R20, it may be required for more aggressive options like 33×12.5R20.
8. Rim Width and Height
The rim size is vital for compatibility. Most GMC Sierras with a 2-inch leveling kit use rims ranging from 18 to 22 inches in diameter and 9 to 10 inches in width. For instance:
- 20×9 inch rims: Fit well with 275/60R20 or 285/55R20.
- 22×10 inch rims: Work best with wider tires like 305/45R22.
9. Tire Pressure and Maximum Ratings
Proper inflation ensures safety and performance. LT tires often have a maximum pressure of 80 psi, while P tires max out around 44 psi. Always adhere to the manufacturer-recommended pressure based on your tire size and load requirements.
10. Decoding Tire Numbers
Understanding tire specifications is crucial when selecting what size tire for GMC Sierra with 2 inch leveling kit. Let’s break down 275/60R20:
- 275: Tire width in millimeters.
- 60: Aspect ratio, indicating sidewall height as a percentage of the width.
- R20: Radial construction and 20-inch rim diameter.
This size offers a balance of stability, and aesthetics, making it a top choice for leveled trucks.
Conclusion
Deciding what size tire for GMC Sierra with 2 inch leveling kit depends on factors like clearance, load capacity, and driving needs. Popular sizes include 275/60R20, 285/55R20, and 33×12.5R20, catering to various preferences and uses. By ensuring proper fitment and understanding tire measurements, you can upgrade your GMC Sierra for improved performance, style, and versatility.
