Tire sizes by trim

The 2018 Tesla Model X offered a range of tire and wheel options depending on the trim and selected packages. Tesla often uses a staggered setup, meaning the front and rear tires are different sizes to optimize performance and handling. It's important to note that specific availability could vary.

Note: Always check your vehicle's door placard for the most accurate and up-to-date tire size and pressure information for your specific Model X.

Recommended replacement tires

When replacing tires on your 2018 Tesla Model X, it's crucial to select tires that meet or exceed the original equipment specifications for load capacity, speed rating, and performance. Given the Model X's weight, instant torque, and focus on efficiency, high-quality tires designed for CUVs/SUVs, often with a "T0", "T1", or "T2" (Tesla specific) marking, are recommended. Prices can vary significantly based on brand, performance, and where you purchase them.

• Michelin Pilot Sport All Season 4: A popular choice for its excellent blend of dry and wet performance, long tread life, and comfortable ride. Often comes as an OEM option for Tesla. (Premium Price Tier)
• Pirelli Scorpion Zero All Season: Another strong contender offering good all-around performance, especially in varying weather conditions. (Premium Price Tier)
• Continental CrossContact LX Sport: A good balance of comfort, quietness, and handling, often chosen for its durability. (Mid-Premium Price Tier)
• Goodyear Eagle F1 Asymmetric 3 SUV: Designed for sporty SUVs, offering strong grip and handling. (Mid-Premium Price Tier)

When to inflate to max load psi

This section is primarily for heavy-duty trucks. The 2018 Tesla Model X is a passenger electric SUV and does not typically require inflation to "max load PSI." Always adhere to the recommended cold tire pressures found on your vehicle's door placard for optimal safety, performance, and tire longevity. Inflating to the maximum pressure listed on the tire's sidewall is generally not recommended for everyday driving as it can lead to a harsher ride, uneven tire wear, and potentially reduced grip.

Lug nut torque & pattern

The correct lug nut torque is vital to ensure your wheels are securely fastened to your vehicle without being overtightened, which can cause damage to the stud or wheel.

• Lug Nut Torque: 129 ft-lb (175 Nm)
• Bolt Pattern: 5x120 (This means there are 5 lug nuts with a 120 mm diameter bolt circle.)

Always use a calibrated torque wrench when tightening lug nuts and follow a star or crisscross pattern to ensure even seating of the wheel against the hub.

Common tire issues for this vehicle

Owners of 2018 Tesla Model X vehicles occasionally report specific tire-related issues, often stemming from the vehicle's characteristics:

• Rapid Tire Wear: Due to the Model X's heavy weight and instant torque, tires, especially on performance models, can wear more quickly than on lighter vehicles. Regular tire rotations (if applicable to your staggered setup) and proper inflation are crucial.
• Inner Edge Wear and Alignment: Some owners experience premature wear on the inner edges of tires. This can often be attributed to vehicle alignment settings. Regular alignment checks are recommended, particularly if you notice uneven wear.
• Noise: As tires wear, or if specific tire compounds are used, increased road noise can become noticeable. Tire choice can significantly impact cabin noise levels.
• Puncture Concerns (No Spare): Without a spare tire, punctures can be a greater inconvenience. The included tire repair kit is for minor punctures; more significant damage will require a tow.
• TPMS Sensor Issues: While generally reliable, TPMS sensors can occasionally malfunction, require reprogramming after tire changes, or have batteries that deplete over time (typically 5-10 years).
