2019 Tesla Model X — Wiper Blade Sizes

Quick reference

Note: Most 2019 Model X vehicles use the sizes above, but always verify against your VIN or existing blades before purchase.

Best aftermarket replacements

• Bosch ICON (beam): Premium performance and durability; excellent in all weather. Price: typically $25–35 each. Look for sizes 26" (driver), 19" (passenger), and 14" (rear) with a top-lock adapter included.
• Rain-X Latitude Water Repellency (beam): Great value with built-in water-repellent coating. Price: ~$18–28 each. Ensure the package lists a 19 mm top-lock/push-button adapter.
• Trico Force or Trico Titan (beam): Aerodynamic beam blades made for highway stability. Price: ~$20–30 each. Confirm the correct top-lock adapter.
• Michelin Stealth Ultra (hybrid): Sturdy frame with beam-like contact. Price: ~$15–25 each. Verify adapter compatibility with Tesla’s push-button arm.
• PIAA Si-Tech (beam, silicone): Long-lasting silicone rubber for quiet wipes. Price: ~$30–40 each. Choose the sizes above and use the included top-lock fitting.

Tip: Many beam blades are sold as single units. Buy the exact sizes for each position and confirm the adapter kit includes “top-lock 19 mm” (sometimes called push-button or PTB).

Attachment style

The 2019 Tesla Model X uses a push-button (top-lock, ~19 mm) wiper arm for the front positions. You’ll release a center button/tab to slide the blade on or off the arm’s top-lock rail. This is different from the common J-hook and side-pin styles found on other vehicles. The rear arm uses a compact push-button/side-lock style specific to rear applications.

• J-hook: Not typical on Model X front arms.
• Side pin/bayonet: Not typical on Model X front arms.
• Push-button/top-lock: Standard on Model X front; be sure your replacement blade includes this adapter.

How to install

1. Enable Wiper Service Mode: On the touchscreen, go to Controls > Service > Wiper Service Mode. This lifts the front wipers for safe access.
2. Protect the glass: Place a towel on the windshield in case the arm springs back.
3. Remove the old blade (front): Press the release on the push-button/top-lock adapter and slide the blade straight off the arm.
4. Fit the correct adapter: Select the top-lock (19 mm) adapter from the blade’s kit if it isn’t preinstalled.
5. Install the new blade: Align the adapter channel with the arm’s top-lock rail, slide until it clicks and locks. Tug gently to confirm it’s secure.
6. Rear blade: Lift the rear arm, press the small release tab, and slide the blade out; reverse to install the new 14" blade.
7. Exit Service Mode and test: Lower the arms carefully, turn off Wiper Service Mode, and test all speeds and washer spray.

Note: If your arm/adapter looks different, consult the blade’s instruction sheet for the alternate push-button variant. Do not force a J-hook adapter onto a top-lock arm.

When to replace

Replace wiper blades every 6–12 months, or sooner if you notice:

• Streaking, smearing, or missed areas
• Chattering or squeaking
• Split, nicked, or hardened rubber
• Poor performance in heavy rain or at highway speeds

Fresh blades improve visibility and reduce eye strain—especially important on the Model X’s expansive windshield.
