Ken-Tool Tire String
Ken-Tool Tire String: Professional-Grade Repair from a Century-Old Leader
When a nail or screw finds its way into a tubeless tire, having the right repair material on hand can mean the difference between a quick roadside fix and a full-blown delay. Tire string — also known as tire repair string inserts or plug strings — are rubber composite strips threaded into punctures to seal the injury from the inside out, restoring air retention without removing the tire from the rim. For professionals and serious DIYers alike, the brand behind those strings matters enormously, and few names carry more weight in the tire service world than Ken-Tool.
A Century of Tire Service Expertise
Ken-Tool's roots trace back to 1920, when John A. Kennedy invented the Pacific Rim Tool and began selling it to garages and tire shops across the country. Over a century of focused innovation has made Ken-Tool the world's leading manufacturer of tire service tools, with a sprawling product catalog built entirely around the demands of tire professionals. Headquartered in Akron, Ohio — the historic heart of the American rubber industry — Ken-Tool brings that same depth of expertise to every product category it touches, including tire string repair inserts.
Why Ken-Tool Tire String Stands Out
Ken-Tool's manufacturing heritage is rooted in precision forging — drop hammer, upsetter, and press forging techniques refined over decades. That commitment to quality materials and exacting production standards carries directly into their tire string lineup. Professionals trust Ken-Tool tire strings because they are engineered to meet the real-world demands of busy tire shops and roadside service fleets, not just occasional DIY use.
Tire string inserts from Ken-Tool are designed to be inserted into punctures in tubeless tires — passenger cars, light trucks, commercial vehicles, ATVs, and more — typically with a plug insertion tool, sealing the injury quickly and reliably. Their selection of 19 tire string SKUs ensures technicians can find the right diameter, length, and compound for a wide range of puncture sizes and tire types. Whether you need standard brown string inserts for everyday passenger tire repairs or specialty variants for heavier-duty applications, Ken-Tool's lineup covers the spectrum.
Built for the Shop, Trusted on the Road
Ken-Tool products are a staple in professional tire service environments. Their tire strings pair naturally with Ken-Tool's broader ecosystem of tire repair and service tools, making it easy to stock a consistent, professional-grade repair solution across your entire operation. With over a century of industry presence and a slogan — "Wherever Tires Are Changed" — that has proven true decade after decade, Ken-Tool remains a benchmark brand for anyone who takes tire repair seriously.
