When your car tire gets punctured or leaks air, these repair nails work fast. Once inserted, the thick threads in the middle of each nail create a tight bond with the tire, forming a reliable and airtight seal. No flaring tools needed — reduces the risk of secondary damage to the tire! Simply check the size of the puncture hole, select the appropriate nail, and use the included screwdriver to screw the nail directly into the hole. Made of high-grade carbon steel + rubber, these nails offer excellent durability and firmness for a long service life. They won't easily fall out or fail, even when driving on rough mountain roads. Each repair nail has its own "home" — a plastic capsule that prevents breakage. All are stored in a transparent box for easy carrying. This tire repair kit is widely suitable for cars, mountain bikes, motorcycles, trucks, vans, and other vehicles.
