Tesla Model 3: Tire - Front - LH (Repair)

DRAFT

Inspection

1. Remove the wheel. See Wheel (Remove and Install).
2. Inspect the outside of the tire. If any of these conditions exist, stop the procedure and replace the tire. See Tire - Front - LH (Dismount and Mount). Do not repair the tire.

• The puncture is in the shoulder or sidewall.
• The object entered the tire at more than a 15 degree angle from perpendicular.
• The object is more than 1/4" in diameter.
• The tread depth is less than 1/16".
• There are cracks deeper than 1/16" on the sidewall.
• The tire is more than 10 years old.

3. Dismount the tire from the wheel. See Tire - Front - LH (Dismount and Mount). Note: Mark the tire and wheel mounting locations, to simplify balancing later.
4. Inspect the inside of the tire. If any of these conditions exist, stop the procedure and mount a new tire onto the wheel. See Tire - Front - LH (Dismount and Mount). Do not repair the tire.

• There is evidence that the tire was driven flat. This is identified by inner sidewall cracking, separation, or a blue-ish color.
• A previous repair is close enough to the puncture that repair areas will overlap.
• Improper previous repair.
• Broken, kinked, or damaged beads.
• Any visible internal damage.

5. Repair the tire. See Repair

Repair

1. Mark the location of the puncture on both the outside and inside of the tire.
2. Remove the object.
3. If the tire has a foam sound absorber, cut out a section of the foam with a radius of 50 mm from the puncture.
4. Use the carbide cutter to clean the puncture.
5. Inside the tire, center a minicombi insert over the puncture, and trace a circle approximately 15 mm larger than the insert.
6. Apply pre-buff cleaner to the traced area.
7. Use the liner scraper to scrape the traced area.
8. Repeat step 6 and step 7 until the traced area is fully cleaned.
9. Lightly buff the traced area until smooth. Note: If the cords are exposed, stop the procedure and mount a new tire onto the wheel. See Tire - Front - LH (Dismount and Mount).
10. Vacuum any debris from the inside of the tire.
11. Apply blue cement into the puncture and apply a thin layer to the traced area.
12. Remove the protective cover from the minicombi insert and insert the guide pin into the puncture and out through the tire tread.
13. Use pliers to pull on the guide pin until the base of the minicombi insert is flush with the inside surface of the tire, and there is a slight dimple.
14. Roll the stitcher over the base working from the center outward, to fully adhere the base to the tire.
15. Remove the protective cover from the base and apply generous amounts of sealant to the base and traced area.
16. Cut the guide pin flush to the tread.
17. Mount the tire onto the wheel. See Tire - Front - LH (Dismount and Mount). Note: Use the locating marks made before dismounting the tire.
