Don't let a flat tire slow you down. Temporary tire repair strings can get you back on the road without having to dismount the tire from its rim. Works for any passenger car's tubeless tires. These repairs are constructed of twisted cord permeated with butyl rubber inside and out. The high tensile cord assures no breakage during insertion while the soft and tacky butyl rubber seals the injury. These string repair units are for emergency temporary repairs only. The damaged tire should be taken to a repair facility and removed from the rim for inspection and for a proper repair.
