Setup and Installation

Proper installation is crucial for tire safety and performance. It is highly recommended that tire installation be performed by a qualified professional using appropriate equipment.

Pre-Installation Checks:

• Compatibility: Ensure the tire size (235/75R15), load index (109), and speed rating (T) match your vehicle's specifications as recommended by the vehicle manufacturer.
• Rim Condition: Inspect rims for damage, corrosion, or deformation. Only use rims that are in good condition and of the correct size (15 inches diameter, 15 inches width).
• New Valve Stems: Always install new valve stems when mounting new tires to ensure proper air retention.

Mounting and Balancing:

1. Mounting: Use proper tire mounting equipment to avoid damage to the tire bead or rim. Lubricate the tire beads and rim flanges with an approved tire lubricant.
2. Inflation: Inflate the tire slowly and carefully, ensuring the beads seat correctly on the rim. Never exceed 40 psi (2.75 bar) to seat beads unless specified otherwise by the tire manufacturer. Once seated, adjust to the vehicle manufacturer's recommended operating pressure.
3. Balancing: Dynamically balance all new tires on the rim to prevent vibrations and ensure even wear.

Operating Guidelines

Adhering to correct operating procedures is vital for safety and maximizing tire life.

• Tire Pressure: Maintain tire inflation pressure at the level recommended by your vehicle manufacturer, typically found on a placard in the door jamb, glove compartment, or owner's manual. Check pressure monthly when tires are cold.
• Load Capacity: Do not exceed the maximum load capacity of 1399.79 kg per tire (Load Index 109). Overloading can lead to tire failure and unsafe driving conditions.
• Speed Rating: The Presa PJ88 has a speed rating of 'T', which corresponds to a maximum speed of 190 km/h (118 mph). Never exceed the tire's speed rating or the legal speed limit.
• Driving Habits: Avoid sudden acceleration, harsh braking, and aggressive cornering, as these can accelerate tire wear and reduce fuel efficiency.
• Road Hazards: Exercise caution when driving over potholes, curbs, or other road hazards that could damage tires.

Maintenance

Regular maintenance extends tire life and ensures safe operation.

• Tire Rotation: Rotate tires every 8,000 to 10,000 km (5,000 to 6,000 miles) or as recommended by your vehicle manufacturer. This promotes even wear across all tires.
• Wheel Alignment: Have your vehicle's wheel alignment checked periodically, especially if you notice uneven tire wear or steering issues.
• Tread Depth: Regularly inspect tread depth. Replace tires when the tread wears down to 1.6 mm (2/32 inch), indicated by the tread wear indicators (bars molded into the tread grooves).
• Visual Inspection: Periodically inspect tires for cuts, cracks, bulges, punctures, or other signs of damage. Any damage should be inspected by a tire professional immediately.
• Cleaning: Clean tires with mild soap and water. Avoid harsh chemicals that can degrade rubber compounds.
