Frequently Asked Questions
How do these tire repair strings compare to regular rubber plugs?
KEX-363 strings use chemical curing fiber technology that forms stronger bonds with tire rubber than basic plugs. The blue poly wrap adds durability compared to standard plugs, making these suitable for professional shops requiring reliable temporary repairs until permanent patching.
What size punctures do these repair strings work on?
These 3/16" diameter strings work on standard nail and screw punctures in passenger car and light truck tires. They effectively seal punctures up to the string diameter size, typically from roofing nails, screws, and similar debris. Not suitable for large tears, sidewall damage, or punctures exceeding 1/4 inch diameter.
Are these suitable for permanent tire repairs?
No, KEX-363 strings are temporary emergency repairs only designed to get vehicles safely to tire shops. They provide reliable sealing for emergency situations but must be replaced with proper permanent inside patches. Tire industry safety standards require inside patching with patch-plug combinations for permanent repairs.
How long do these tire repair strings typically last?
When properly installed, these strings provide temporary sealing for several weeks to months depending on driving conditions and tire pressure maintenance. They should be replaced with permanent inside patches within 2-4 weeks for optimal safety. Highway speeds, heavy loads, and temperature extremes may reduce their effective lifespan.
