Zaj\u00edmav\u00e1 je tak\u00e9 historie n\u00fdtovac\u00ed matice. Vymyslela to americk\u00e1 firma BF GoodRich v roce 1930, kter\u00e1 sv\u00e9ho \u010dasu byla jedna z nejv\u011bt\u0161\u00edch v\u00fdrobc\u016f pneumatik na sv\u011bt\u011b, pozd\u011bji zakoupen\u00e1 francouzskou spole\u010dnost\u00ed Michelin. Firma se toti\u017e nezab\u00fdvala pouze automobilov\u00fdmi pneumatiky, ale tak\u00e9 pneumatiky pro letadla a pot\u00e9 vstoupila i do leteck\u00e9ho pr\u016fmyslu, kde pr\u00e1v\u011b do\u0161lo k vymy\u0161len\u00ed n\u00fdtovac\u00ed matice.
