11R22.5 RIB TYPE Tires
Proper Maintenance Guide
The 11R22.5 RIB TYPE tire is commonly used for steer axles and long-haul applications due to its straight rib tread design. To maximize its lifespan and ensure safety and fuel efficiency, proper maintenance is essential.
✅ 1. Regular Inspection
Frequency: Daily walk-around + Weekly detailed check
Check for:
• Uneven tread wear
• Cuts, cracks, or punctures
• Bulges or sidewall damage
• Objects stuck in the tread
• Loose or missing valve caps
🔧 Tip: Use a flashlight to inspect tire grooves and sidewalls thoroughly.

✅ 2. Tire Pressure Maintenance
Recommended PSI for 11R22.5:
Usually between 115 to 120 PSI, depending on load and manufacturer specs.
• Check tire pressure when cold
• Use a calibrated pressure gauge
• Inflate or deflate based on load charts
• Avoid overinflation (can cause wear at the center)
• Avoid underinflation (causes sidewall flexing and heat buildup)
📉 Underinflation is the #1 cause of tire failure.

✅ 3. Proper Wheel Alignment
• Misalignment causes shoulder wear and vibration
• Check alignment every 20,000–30,000 km or when:
o You notice uneven wear
o After hitting potholes or curbs
o After suspension work
⚠️ Rib tires are especially sensitive to poor alignment.

✅ 4. Tire Rotation
• Rotate tires every 10,000–15,000 km
• Helps prevent irregular wear
• Always follow the manufacturer’s rotation pattern
🔁 For steer tires, sometimes cross-rotation is avoided — check brand guidance.

✅ 5. Balancing and Matching
• Balance new tires upon installation
• Rebalance if:
o You feel vibration
o There’s spot wear
• Dual tires? Match diameters within ¼ inch to prevent drag.
________________________________________
✅ 6. Proper Loading Practices
• Avoid overloading your vehicle
• Distribute weight evenly
• Overload causes excess heat and sidewall damage
📚 Use axle scales and follow DOT regulations.
________________________________________
✅ 7. Tread Depth Monitoring
(Depending on fleet or company standards)
• Minimum legal tread depth:
o Steer tires: 4/32 inch (≈3.2 mm)
o Drive/trailer tires: 2/32 inch (≈1.6 mm)
• Measure with a tread depth gauge
• Replace if irregular wear or below legal limit
________________________________________
✅ 8. Storage Best Practices (If Not in Use)
• Store in a cool, dry place, away from sunlight
• Stack vertically, or hang if possible
• Keep away from chemicals or oil spills
• Avoid prolonged contact with wet surfaces
