Understanding the operating characteristics of your tires is essential for safe driving and maximizing tire life.

3.1 Tire Pressure

Maintain correct tire inflation pressure as specified by your vehicle manufacturer, typically found on a placard inside the driver's side door jamb, glove compartment, or owner's manual. Check tire pressure regularly, at least once a month and before long trips, when tires are cold.

3.2 Load Capacity

The Yokohama Geolander A/T G015 (size 215/70R16 100H) has a maximum load capacity of 1764 pounds per tire. Do not exceed the maximum load capacity of your tires or your vehicle's Gross Vehicle Weight Rating (GVWR).

3.3 Speed Rating

The 'H' speed rating indicates a maximum speed capability of 130 mph (210 km/h) under specified conditions. Always adhere to legal speed limits and adjust driving speed to road and weather conditions.

4. Maintenance

Regular maintenance extends tire life and ensures consistent performance.

4.1 Tire Rotation

Rotate your tires every 5,000 to 8,000 miles (8,000 to 13,000 km) or as recommended by your vehicle manufacturer. This helps promote even tread wear across all four tires.

4.2 Inspection for Wear and Damage

Periodically inspect your tires for:

• Tread Wear: Check for uneven wear patterns, which can indicate issues with alignment, balancing, or inflation.
• Tread Depth: The new tread depth is 12/32nds. Replace tires when the tread depth reaches 2/32nds of an inch (1.6 mm), indicated by tread wear indicators (bars molded into the tread grooves).
• Damage: Look for cuts, punctures, bulges, cracks, or other signs of damage. Any significant damage should be inspected by a tire professional immediately.

4.3 Cleaning

Clean tires with mild soap and water. Avoid harsh chemical cleaners that can degrade rubber compounds.
