2020-2025 Model S & 2021-2025 Model X Wheel Cap Guide: Tempest, Cyberstream & Arachnid
This guide clarifies the critical differences between Tesla's aero covers and center caps to ensure you buy the right part for your specific wheels.
- Compatibility is critical: Tesla uses large 'Aero Covers' for 19" Tempest wheels and small 'Center Caps' for 20" Cyberstream and 21" Arachnid wheels. They are not interchangeable.
- When buying a used cap, the condition of the plastic retaining clips on the back is the most important factor; broken clips will cause rattling or detachment.
- Rattling from an aero cover is a very common issue that can often be fixed with foam tape or by bending the metal tension clips, avoiding the cost of a new cover.
- Installation is a simple DIY task. Always align the cover with the valve stem and press firmly until all clips snap into place to prevent it from falling off.
Wheel Cap & Cover Compatibility for Model S and Model X
One of the most confusing aspects of buying a replacement wheel cap for a 2020-2025 Tesla Model S or 2021-2025 Tesla Model X is understanding the different types available and which wheels they fit. Tesla uses two primary styles: large, full-face 'Aero' wheel covers and smaller, pop-in center caps. Compatibility is strictly determined by the wheel style and size equipped on the vehicle.
Warning: Before purchasing, physically inspect your wheels and identify their style name. The parts are not interchangeable between wheel styles.
| Vehicle | Wheel Style & Size | Part Type | Known OEM Part Number |
|---|---|---|---|
| 2020-2025 Model S | 19-inch 'Tempest' | Full Aero Wheel Cover | 1486286-00-A |
| 2021-2025 Model S | 21-inch 'Arachnid' | Center Cap | 1420238-00-A |
| 2021-2025 Model X | 20-inch 'Cyberstream' | Center Cap | 1420238-00-A |
Pro Tip: Owners of the 19-inch 'Tempest' wheels have options. You can use the full aero cover (1486286-00-A) for maximum range, or you can remove it and expose the underlying alloy wheel. To finish that look, you can purchase a separate, smaller center cap and lug nut cover kit, which is widely available in the aftermarket.
🎬 Watch: How to remove Tempest covers and install center caps.Common Symptoms and Known Issues
Failure of a wheel cap is typically audible or visual, rather than mechanical.
- Rattling or Clicking Noises: This is the most frequent complaint, especially with the full-face Tempest aero covers. The noise is most noticeable at low speeds and occurs when the plastic retaining clips or the metal tension springs on the back of the cover become weak or loose. Repeated removal and installation can accelerate this wear.
- Missing Cover or Cap: Covers can detach from the vehicle, often after hitting a pothole or if not installed correctly. Proper installation requires aligning the cover with the valve stem and pressing firmly around the entire perimeter until all clips are engaged.
- Cosmetic Damage: Scuffs, scratches, and cracks from curb impacts are common. While minor scuffs are cosmetic, a significant crack can weaken the cover's structure, leading to rattles or detachment. Some owners note that the factory aero covers do not fully protect the outer rim of the wheel from curb rash.
- Damage to Wheels: Some owners have reported that the plastic clips and edges of the OEM aero covers can scratch or wear away the paint on the alloy wheels underneath over time. 🎬 See how OEM covers can cause damage to your rims.
Pro Tip: A rattling aero cover can often be fixed without replacement. Applying foam padding tape to the inside perimeter of the cover can create a snugger fit and eliminate noise. Alternatively, the metal tension clips on the back can be carefully bent with pliers to increase their tension.

As of early 2026, there are no official recalls or Technical Service Bulletins (TSBs) from Tesla or the NHTSA specifically for the wheel caps or covers on these models. Issues like rattling are typically handled by owners with DIY fixes or, in some cases, replaced under warranty if the vehicle is new.
Buying a Used Wheel Cap: What to Inspect
A used OEM wheel cap is an excellent value, but a thorough inspection is key to avoiding problems. Focus on the back of the cap, as the structural integrity is more important than minor face scuffs.
- Check All Retaining Clips: This is the most critical inspection point. Carefully examine each plastic clip on the back of the cover. Reject any cap with cracked, broken, or missing clips. These are the primary cause of rattles and detachment.
- Test the Tension Springs: For full-face covers like the Tempest, there are metal tension springs integrated with the plastic clips. Gently squeeze them to ensure they still have springiness and are not rusted or weak.
- Inspect for Cracks: Check the entire cap, front and back, for cracks. A small surface scuff from a curb is usually just cosmetic, but a crack that goes all the way through the plastic means the part is compromised and should be rejected.
- Verify the Part Number: Flip the cap over and find the part number molded into the plastic. Match it to the numbers in the compatibility table above (e.g., 1486286-00-A for a Tempest cover, 1420238-00-A for a Cyberstream/Arachnid center cap) to guarantee you're buying the correct part.
Replacement Guide
Replacing a wheel cap or cover is a simple DIY task that requires no special tools.
- Difficulty: 1/5
- Time: Less than 5 minutes
Removal: Grasp the wheel cover firmly with both hands and pull it straight toward you to release the retaining clips. For smaller center caps, a suction cup or even a piece of strong duct tape can sometimes be used to pull it out. Tesla also makes a specific lug nut cover tool that can be used to pry the center cap off.
Installation: Align the notch or symbol on the cover with the wheel's valve stem. Press firmly in the center to begin seating the cap, then work your way around the perimeter, pressing on each spoke or section until you hear and feel it snap securely into place. As a final check, gently pull on the edges to ensure it is fully secured.
Cost Comparison

Frequently Asked Questions (FAQ)
Can I use the smaller center cap on my 19-inch Tempest wheels?
Yes. The 19-inch Tempest wheels have a finished alloy wheel underneath the aero cover. You can remove the full cover and install a smaller center cap and lug nut cover kit for a different look. These kits are widely available from aftermarket suppliers.
Are aftermarket wheel covers a good option?
They can be, but quality varies widely. Many owners use aftermarket covers to change the style of their wheels or to get a design that offers more protection for the wheel rim. However, be aware of potential issues like poor fitment, rattling noises, or even detaching while driving. Reading reviews for the specific brand and style is highly recommended.
Will a missing wheel cover affect my car's performance?
A missing smaller center cap will not affect performance at all. A missing full-face aero cover, like the Tempest cover, may slightly decrease your vehicle's aerodynamic efficiency, which could result in a very minor reduction in driving range, but it is not a safety concern.
Why does my Tesla app say the wheel cover isn't compatible with my car?
This can happen if you are trying to order a part for a wheel design that wasn't original to your vehicle's specific build year, even if it's the same model. For example, the design of the 19-inch wheels on a pre-refresh 2021 Model S is different from the refresh 2021 Model S, and their respective Tempest covers are not interchangeable.
