Co se t\u00fd\u010de zimn\u00edch pneumatik, i k t\u011bm se vyjad\u0159uje Michael M\u00fcller, \u0161\u00e9f testov\u00e1n\u00ed ADACu. Podle n\u011bj nelze komer\u010dn\u011b vyr\u00e1b\u011bt ide\u00e1ln\u00ed pneumatiky do sn\u011bhu, proto\u017ee v zim\u011b v\u011bt\u0161inu \u010dasu panuj\u00ed i jin\u00e9 podm\u00ednky.\u00a0 \u0160\u00ed\u0159kou zimn\u00edch pneumatik se tak\u00e9 zab\u00fdval v testu pneumatik 255\/45 R17 s rychlostn\u00edm indexem 240km\/h. Vzhledem k jejich \u0161\u00ed\u0159ce byla j\u00edzda v sn\u011bhov\u00e9 b\u0159e\u010dce a na silnici pokryt\u00e9 vodou j\u00edzda a\u017e nebezpe\u010dn\u00e1<\/strong>, proto\u017ee se pod pneumatikou vytvo\u0159ila vrstva vody a auto se stalo neovladateln\u00fdm. Proto ADAC na zimu doporu\u010duje sp\u00ed\u0161e u\u017e\u0161\u00ed pneumatiky<\/strong>, proto\u017ee se l\u00e9pe dok\u00e1\u017e\u00ed vypo\u0159\u00e1dat s krizov\u00fdmi situacemi, kter\u00e9 v zim\u011b mohou nastat.<\/p>\n

Naopak v\u00fdrobce pneumatik Continental<\/a> na to jde opa\u010dn\u011b – \u0161ir\u0161\u00ed pneumatiky<\/strong> maj\u00ed v\u011bt\u0161\u00ed sty\u010dnou plochu s vozovkou, tud\u00ed\u017e lep\u0161\u00ed p\u0159ilnavost<\/strong>. To Continental roz\u0161i\u0159uje i na zimn\u00ed pneumatiky – proto\u017ee kdy\u017e vozidlo jede p\u0159es zmrzl\u00fd sn\u00edh a led, p\u0159ilnavost je kl\u00ed\u010dov\u00e1. \u0160ir\u0161\u00ed pneumatiky maj\u00ed v\u00edce hran blok\u016f a lamel, co\u017e zvy\u0161uje t\u0159en\u00ed.<\/strong> To znamen\u00e1 lep\u0161\u00ed p\u0159ilnavost, a tedy lep\u0161\u00ed ovladatelnost, akceleraci a brzd\u011bn\u00ed<\/strong>. To podle Continentalu vede k celkov\u011b lep\u0161\u00edmu v\u00fdkonu pneumatiky, zejm\u00e9na v zat\u00e1\u010dk\u00e1ch a pr\u00fd i na\u00a0 sn\u011bhu. Continental na druhou stranu uzn\u00e1v\u00e1, \u017ee trakce v hlubok\u00e9m \u010derstv\u00e9m sn\u011bhu bude v\u017edy lep\u0161\u00ed u\u017e\u0161\u00ed pneumatika, proto\u017ee se s men\u0161\u00ed plochou pneumatiky m\u00e1 mnohem v\u011bt\u0161\u00ed \u0161anci ze sn\u011bhu “vyhrabat.”<\/strong><\/p>\n

Na tom se shodne jak ADAC, tak i Continental – v hlubok\u00e9m sn\u011bhu jsou prost\u011b lep\u0161\u00ed u\u017e\u0161\u00ed pneumatiky.<\/strong> Je tak na zv\u00e1\u017een\u00ed ka\u017ed\u00e9ho, jak \u010dasto a jestli v\u016fbec se s takov\u00fdmi podm\u00ednkami v zim\u011b setk\u00e1. \u0160ir\u0161\u00ed pneumatiky maj\u00ed lep\u0161\u00ed vlastnosti za standardn\u00edch j\u00edzdn\u00edch situac\u00ed<\/strong>, ale naopak pr\u00e1v\u011b v p\u0159\u00edpad\u011b hlubok\u00e9ho sn\u011bhu nebo aquaplaningu jsou na tom l\u00e9pe u\u017e\u0161\u00ed.<\/p>\n","protected":false},"excerpt":{"rendered":"
