1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your MICHELIN PILOT SPORT 4 S performance tires. Adhering to these guidelines will help ensure optimal performance, safety, and longevity of your tires. Please read this manual thoroughly before use.
2. Setup and Installation
Proper installation is crucial for tire performance and safety. It is strongly recommended that MICHELIN PILOT SPORT 4 S tires be installed by a qualified professional tire technician.
2.1 Professional Installation
Always have tires mounted and balanced by a certified technician using appropriate equipment. Incorrect installation can lead to tire damage, vehicle instability, and potential accidents.
2.2 Vehicle Compatibility
Ensure the tire size and specifications (load index, speed rating) match your vehicle manufacturer's recommendations. Refer to your vehicle's owner's manual or tire placard (typically located on the driver's side door jamb, glove compartment, or fuel filler flap) for correct tire information.
2.3 Mounting and Balancing
Tires must be mounted on approved rims that are free from damage, corrosion, or deformation. Dynamic balancing is essential to prevent vibrations and ensure even wear. Use new valve stems when installing new tires.

3. Operating Guidelines
The MICHELIN PILOT SPORT 4 S is a high-performance summer tire designed for optimal grip and handling in dry and wet conditions. Adhere to the following guidelines for safe and effective operation.
3.1 Speed and Load Ratings
Never exceed the maximum speed rating or load capacity indicated on the tire's sidewall and in the specifications section of this manual. Overloading or exceeding the speed rating can lead to tire failure.
3.2 Driving Conditions
These tires are optimized for summer conditions. They are not intended for use in freezing temperatures, snow, or ice. In such conditions, dedicated winter tires are recommended.
The tire's hybrid reinforcement technology enhances high-speed handling, wear resistance, and overall durability, contributing to consistent performance.

3.3 Aesthetic Features
The MICHELIN PILOT SPORT 4 S features a "Premium Touch" velvet-effect checkered sidewall treatment. This design element is intended to enhance the visual appeal of the tire and the vehicle.
4. Maintenance
Regular maintenance is essential to maximize the lifespan and performance of your MICHELIN PILOT SPORT 4 S tires.
4.1 Tire Pressure
Check tire pressure monthly, or before long trips, using a reliable pressure gauge. Always check when tires are cold. Maintain the pressure recommended by your vehicle manufacturer, not the maximum pressure listed on the tire sidewall. Incorrect pressure can lead to uneven wear, reduced fuel efficiency, and compromised handling.
4.2 Tread Depth
Regularly inspect tread depth. The minimum legal tread depth is typically 2/32 inch (1.6 mm). Replace tires when they reach this limit or show signs of excessive wear. The PILOT SPORT 4 S has a new tread depth of approximately 9.5/32nds.
4.3 Tire Rotation
Rotate your tires according to your vehicle manufacturer's recommendations, typically every 5,000 to 7,500 miles. This promotes even wear across all four tires.
4.4 Wheel Alignment and Balancing
Have your wheel alignment checked periodically, especially if you notice uneven tire wear or steering issues. Re-balance tires if you experience vibrations.
4.5 Inspection for Damage
Visually inspect tires for cuts, punctures, bulges, or other damage. If any damage is found, have the tire inspected by a professional immediately. Avoid driving on damaged tires.
4.6 Storage
If storing tires, keep them in a cool, dry place away from direct sunlight, heat sources, and chemicals that could degrade the rubber.
5. Troubleshooting
This section addresses common issues you might encounter with your tires.
5.1 Uneven Tire Wear
- Cause: Incorrect tire pressure, improper wheel alignment, or lack of tire rotation.
- Solution: Check and adjust tire pressure, have alignment inspected, and follow recommended rotation schedule.
5.2 Vibrations
- Cause: Unbalanced wheels, bent rim, or damaged tire.
- Solution: Have tires re-balanced and inspected for damage or bent rims by a professional.
5.3 Loss of Air Pressure
- Cause: Puncture, faulty valve stem, or bead leak.
- Solution: Inspect the tire for punctures. If found, seek professional repair. Ensure valve stems are in good condition.
5.4 Noise Considerations
The MICHELIN PILOT SPORT 4 S incorporates Acoustic Technology designed to reduce cabin noise. However, perceived noise levels can vary based on vehicle type, road surface, and driving conditions. If you experience unusual or excessive noise, consult a tire professional for inspection.
