Tire Repair Screws (also called Rubber Nail Screws or Vacuum Tyre Repair Nails) are self-tapping metal screws with a rubber sealing ring. They are used to quickly and effectively seal small punctures in tubeless tires without needing to remove the tire from the rim.
What’s Included in the Kit?
- Rubber-coated self-tapping screws (various sizes)
- Sometimes includes screwdriver or hex bit
- Optional: Reamer tool for widening the puncture (not always needed)
Size Chart (Match Screw to Puncture)
| Screw Size | Puncture Diameter | Vehicle Type |
|---|---|---|
| Small | 0.1 – 3 mm | Scooters, Motorcycles |
| Medium | 3 – 5 mm | Cars, SUVs |
| Large | 5 – 7 mm | Trucks, Tractors, Buse |
How to Use Tire Repair Screws (Step-by-Step)
Step 1: Locate the Puncture
- Inflate the tire if it’s flat.
- Use soapy water or listen for a hissing sound to find the puncture.
- Mark the puncture area.
Step 2: Remove the Object
- Pull out the nail, screw, or sharp object causing the puncture using pliers.
Step 3: Clean the Hole (Optional but Recommended)
- Use a reamer tool or small drill bit to clear debris and prepare the hole.
- Ensure the hole matches the screw size.
Step 4: Insert the Rubber Screw
- Take the correct-sized rubber screw.
- Using a screwdriver or hex wrench, rotate clockwise into the hole.
- Do not over-tighten — stop when the rubber head is snug with the tire surface.
Step 5: Inflate the Tire
- Use a portable air compressor or visit a service station.
- Inflate to the recommended PSI.
Step 6: Check for Air Leaks
- Use soapy water around the repair area.
- If bubbles form — tighten screw slightly more or reinsert.

Leak Test
After the screw is inserted and the tire is inflated:
- Apply soap water around the repaired area.
- If no bubbles appear, the seal is good.
- If bubbles form, you may need to:
- Remove and reinsert the screw.
- Use a larger screw.
- Use traditional rubber strip repair.
