Overland Tire Pressure Calculator for Terrain

Calculate the best tire pressure for your vehicle, tire size, terrain, load, and speed to maximize traction, reduce punctures, and improve fuel efficiency.

‍

Essential for switching between highway and off-road conditions.

‍

We ask for vehicle type, terrain type, tire size, load weight, speed range, tire type, and current pressure because these determine safe deflation levels (e.g., 15-18 psi in sand for flotation). These inputs maximize traction and minimize punctures. Limitation: the tool uses general recommendations and may not account for specific tire brand ratings or vehicle suspension; always check sidewall max pressure and test incrementally.

Optimal Tire Pressure for Rock Crawling

Vehicle Details

• Make/Model: Toyota 4Runner/Land Cruiser
• Tire Size: 33-35 inches
• Weight Class: Heavy (1500-3000 lbs)
• Driving Style: Under 20 mph (Slow Crawl)
• Terrain: Rock Crawling
• Tire Type: All-Terrain
• Stock Highway Pressure: 35-40 psi

Recommended Tire Pressure

For your specified conditions, the optimal tire pressures are as follows:

• Front Tires: 15-20 psi
• Rear Tires: 15-20 psi

Safe Pressure Range

• Minimum: 15 psi
• Maximum: 20 psi

Trade-offs: Traction vs. Sidewall Stability

1. Traction:
   • Lowering tire pressure increases the tire's footprint, enhancing grip on uneven and rocky surfaces.
   • Increased contact area allows for better traction, especially in loose or slippery conditions.
2. Sidewall Stability:
   • Deflated tires are more susceptible to sidewall damage from sharp rocks and obstacles.
   • Maintaining some air in the tires helps prevent pinching and improves handling stability during sharp turns or rapid maneuvers.

Deflation Risks

• Pinch Flats: Lower pressures can lead to pinch flats if you hit sharp rocks or obstacles.
• Tire Bead Separation: Excessive deflation can cause the tire bead to separate from the rim, especially on severe inclines or during aggressive maneuvers.
• Temperature & Pressure: Be mindful of temperature changes, as they can affect tire pressure.

Reinflation Tips

1. Portable Air Compressor: Always carry a portable compressor to reinflate tires after off-roading.
2. Tire Pressure Gauge: Use a reliable gauge to monitor tire pressure accurately before and after your runs.
3. Reinflate Gradually: When reinflating, do so gradually to prevent heat build-up in the tire.
4. Check for Damage: Inspect tires for any damage before reinflating, ensuring they are safe for highway driving.

Conclusion

In rock crawling scenarios, optimizing your tire pressure is crucial for balancing traction and sidewall stability. The recommended range of 15-20 psi allows for excellent grip while minimizing the risk of tire damage. Always be prepared for reinflation and monitor your tire conditions closely.
