Tire Sizes by Trim

The 2018 Tesla Model S offered a range of wheel and tire options across its trims. Most configurations either featured a square setup with the same tire size on all four wheels or a staggered setup with wider tires on the rear.

Note: Always refer to your vehicle's door placard for the most accurate and up-to-date tire pressure recommendations, as these can vary slightly based on specific vehicle configuration and tire type.

Recommended Replacement Tires

When replacing tires on your 2018 Tesla Model S, it's crucial to select tires that not only match the OEM size and specifications but also complement the vehicle's performance characteristics. Given the Model S's instant torque and significant weight, tires with excellent grip, low rolling resistance, and good load-bearing capabilities are essential. Road noise and ride comfort are also important considerations.

Here are a few popular options:

• Michelin Pilot Sport 4S (Premium Tier): A favorite among performance car enthusiasts, the Pilot Sport 4S offers exceptional dry and wet grip, precise handling, and a comfortable ride for a performance tire. It's a top choice for those who want to maximize the Model S's dynamic capabilities.
• Continental ExtremeContact Sport 02 (Premium Tier): This tire provides a fantastic balance of performance, comfort, and tread life. It excels in both wet and dry conditions and is known for its quiet ride, making it a great all-around performance option for the Model S.
• Pirelli P Zero (OE/Premium Tier): Often found as original equipment on the Model S, the Pirelli P Zero delivers high-performance handling and grip. While known for its sporty feel, some variations might be more prone to road noise or have a shorter tread life compared to other options.
• Goodyear Eagle F1 Asymmetric 3 (Mid-Premium Tier): The Eagle F1 Asymmetric 3 offers strong performance in wet and dry conditions with good steering response. It's a solid choice for drivers seeking a capable performance tire without necessarily opting for the absolute top-tier price point.
• Hankook Ventus S1 evo3 (Mid-Premium Tier): This tire provides a good balance of performance and value. It offers respectable grip and handling while often being a more budget-friendly option compared to some of the premium brands.

Lug Nut Torque & Pattern

The 2018 Tesla Model S uses a 5x120 bolt pattern. When rotating tires or installing new wheels, it is critical to torque the lug nuts to the manufacturer's specified setting to ensure safety and prevent damage to the wheel or hub.

• Lug Nut Torque: 129 ft-lb (175 Nm)

Always tighten lug nuts in a star pattern to ensure even pressure across the wheel hub and prevent warping of the rotor or wheel.

1. Start with any lug nut.
2. Move directly across to the lug nut diagonally opposite.
3. Continue this star pattern until all lug nuts are hand-tight.
4. Using a torque wrench, tighten each lug nut to the specified torque in the same star pattern.
5. After driving for approximately 50-100 miles, it is highly recommended to re-check the lug nut torque to ensure they have not loosened.

Common Tire Issues for This Vehicle

The Tesla Model S, with its significant weight and instant torque, can sometimes experience specific tire wear patterns or issues:

• Rapid Tire Wear: Due to the vehicle's weight and powerful acceleration, tires, especially on the rear axle, can wear more quickly than on lighter vehicles. Regularly checking tire pressure and proper alignment can help mitigate this.
• Inner Edge Wear: Improper wheel alignment, especially negative camber (wheels tilting inward at the top), can cause accelerated wear on the inner edges of the tires. This is a common issue on performance-oriented vehicles, and regular alignment checks are crucial.
• "Cupping" or Uneven Wear: This can be caused by worn suspension components (shocks/struts), improper tire balancing, or incorrect tire pressure. It often manifests as patches of wear around the tire circumference.
• Road Noise: As tires wear, or if specific tire compounds are used, road noise can increase. Tesla vehicles, being very quiet internally due to their electric powertrains, can make tire noise more noticeable.
• Flat Spots (less common): If a vehicle sits for an extended period, especially in cold weather, tires can develop flat spots. While often temporary, persistent flat spots can lead to vibrations.

Regular tire rotations (if applicable for your specific tire setup, especially for non-staggered), maintaining correct tire pressure, and periodic wheel alignments are key to maximizing tire life and ensuring optimal vehicle performance and safety.
