2018 Tesla Model S Wiper Blade Sizes & Replacement Guide

Maintaining clear visibility in your 2018 Tesla Model S is essential, especially given the vehicle's reliance on clear windshields for Autopilot cameras. Finding the right wiper blades is a simple maintenance task that ensures safety during rain, snow, and sleet.

Quick reference

Here are the wiper blade specifications for the 2018 Tesla Model S. Note that the Model S does not have a rear wiper blade.

Best aftermarket replacements

While you can purchase original blades directly from a Tesla Service Center, several premium aftermarket brands offer fantastic performance, durability, and a perfect fit for the Model S.

• Bosch ICON: (Premium tier) Widely considered the gold standard for beam blades. The ICONs provide exceptional wipe quality and longevity, resisting wind lift at highway speeds.
• Rain-X Latitude: (Mid-to-Premium tier) These beam blades come pre-treated with Rain-X water repellent, coating your windshield as they wipe to bead away water.
• Trico Force: (Mid tier) Designed specifically with a swept-wing spoiler to maintain maximum pressure on the glass, even at higher vehicle speeds.
• Michelin Stealth: (Mid tier) A hybrid blade design that combines the flexibility of a beam blade with the durability of a traditional hinged frame.
• PIAA Si-Tech: (Premium tier) Silicone blades that last incredibly long and leave an active water-repellent barrier on your windshield.

Attachment style

The 2018 Tesla Model S uses a push-button (sometimes referred to as a narrow pinch-tab/push-button) attachment style. This is a very secure and easy-to-swap mechanism. When buying aftermarket blades, ensure the package states it includes adapters for push-button or PTB (Pinch Tab Button) arms.

How to install

Replacing the wipers on a 2018 Tesla Model S requires placing the vehicle in a special mode so you can access the arms without damaging the hood.

1. Enter Service Mode: Sit in the driver's seat, go to the main touchscreen, navigate to Controls > Service > Wiper Service Mode, and turn it ON. The wipers will move to the center of the windshield and stay there.
2. Lift the Wiper Arm: Carefully lift the wiper arm slightly away from the glass.
3. Remove the Old Blade: Press the square push-button on the top of the wiper attachment joint and slide the blade down the arm to remove it.
4. Install the New Blade: Slide the new blade into the wiper arm until you hear and feel the push-button click firmly into place.
5. Lower the Wiper: Gently lay the wiper back against the windshield.
6. Exit Service Mode: Turn off Wiper Service Mode on the touchscreen to return the wipers to their resting position.

When to replace

For optimal safety and Autopilot camera clarity, you should replace your wiper blades every 6 to 12 months. Look out for these common signs that your blades are failing:

• Streaking or smearing water across the glass instead of clearing it.
• Chattering or skipping noises as the blade moves across the windshield.
• Torn or cracked rubber along the squeegee edge.
