Yokohama Geolandar AT G015 All-Terrain Tire User Manual
Model: P255/75R17 113T
Brand: Yokohama
Introduction
The Yokohama Geolandar A/T G015 is an all-terrain tire engineered for pickup trucks, SUVs, and crossovers. This tire is designed to perform reliably in all weather conditions, offering a balanced blend of practical on-road performance and robust off-road capability. It is certified for severe snow service (3PMSF), ensuring confident grip and traction in moderate to extreme ice and snow conditions. The tire's construction features a flatter profile and a cut-and-chip-resistant Enduro compound, which contribute to enhanced treadwear and extended longevity. Additionally, its circumferential grooves are designed to efficiently clear water from the tread, resisting hydroplaning and improving wet performance.
Product Features
- All-Terrain Performance: Designed for versatile use on both paved roads and challenging off-road terrains.
- All-Weather Capability: Suitable for various weather conditions, including severe snow, indicated by the Three-Peak Mountain Snowflake (3PMSF) certification.
- Enhanced Durability: Features a cut-and-chip-resistant Enduro compound and Endurocore construction for increased strength and longevity, especially when carrying heavy loads.
- Wet Traction: Circumferential grooves effectively evacuate water to reduce hydroplaning and improve grip on wet surfaces.
- Comfortable Ride: Engineered to provide a surprisingly comfortable and quiet ride on highways, despite its all-terrain capabilities.

Setup and Installation
Proper installation of the Yokohama Geolandar AT G015 tire is crucial for safety and optimal performance. It is highly recommended that these tires be installed by a qualified professional tire technician using appropriate equipment and following industry standards.
Key Installation Considerations:
- Matching Tires: Ensure all four tires are of the same size, type, and construction, or as recommended by the vehicle manufacturer.
- Wheel Compatibility: Verify that the tire size is compatible with your vehicle's wheel rim width. Refer to the tire specifications and your vehicle's owner's manual.
- Mounting and Balancing: Tires must be correctly mounted on the wheel and dynamically balanced to prevent vibrations and ensure even wear.
- Inflation Pressure: Inflate tires to the vehicle manufacturer's recommended pressure, typically found on a placard inside the driver's side door jamb, glove compartment, or owner's manual. Do not exceed the maximum pressure listed on the tire sidewall.
- Lug Nut Torque: After installation, lug nuts should be torqued to the vehicle manufacturer's specifications. Re-torque after the first 50-100 miles of driving.

Operating Guidelines
The Yokohama Geolandar AT G015 is designed for optimal performance across various driving conditions. Adhering to proper operating guidelines will ensure safety, maximize tire life, and maintain vehicle performance.
- On-Road Driving: These tires provide a smooth and quiet ride on highways. Maintain appropriate speeds and follow all traffic laws.
- Off-Road Driving: The aggressive tread pattern offers excellent grip in mud, dirt, and gravel. Adjust tire pressure as needed for specific off-road conditions, and always drive within the limits of your vehicle and the terrain.
- Snow and Ice: With 3PMSF certification, the Geolandar AT G015 delivers enhanced traction in snowy and icy conditions. Drive cautiously, reduce speed, and allow for increased braking distances.
- Load Capacity: Do not exceed the maximum load capacity specified on the tire sidewall or in your vehicle's owner's manual. Overloading can lead to tire failure and unsafe driving conditions.

Maintenance
Regular maintenance is essential to ensure the longevity, safety, and performance of your Yokohama Geolandar AT G015 tires.
- Tire Pressure: Check tire pressure monthly, including the spare, when tires are cold. Refer to your vehicle's tire placard for recommended inflation pressures. Proper inflation is critical for safety, fuel efficiency, and tire life.
- Tire Rotation: Rotate your tires every 5,000 to 7,500 miles, or as recommended by your vehicle manufacturer. Regular rotation helps promote even tread wear across all four tires.
- Wheel Alignment: Have your vehicle's wheel alignment checked periodically, especially if you notice uneven tire wear, steering pull, or after hitting a significant pothole.
- Tread Depth: Inspect tread depth regularly. The minimum legal tread depth is 2/32 inch. The Geolandar AT G015 has a tread depth of 12/32nds when new. Replace tires when they reach the wear bars.
- Visual Inspection: Periodically inspect tires for cuts, punctures, bulges, or any signs of damage. Remove any stones or debris lodged in the tread grooves.

Troubleshooting
This section addresses common issues you might encounter with your tires and provides general guidance. For severe issues, consult a professional tire technician.
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven Tread Wear | Improper inflation, misalignment, unbalanced wheels, worn suspension parts. | Check and adjust tire pressure. Have alignment and balancing checked by a professional. Inspect suspension components. |
| Vibration or Shimmy | Unbalanced wheels, bent rim, worn suspension, tire damage. | Have wheels re-balanced. Inspect tires and rims for damage. Consult a technician for suspension check. |
| Loss of Air Pressure | Puncture, leaky valve stem, damaged rim, bead leak. | Inspect tire for punctures. Have a professional check valve stems, rims, and tire beads for leaks. |
| Excessive Road Noise | Uneven wear, improper inflation, tire design (all-terrain tires can be louder). | Ensure proper inflation and regular rotation. While all-terrain tires have some inherent noise, excessive noise may indicate wear issues. |
