Test “ojet\u00fdch” pneumatik<\/h2>\n

V testu bylo 5 celoro\u010dn\u00edch pneumatik od p\u0159ev\u00e1\u017en\u011b pr\u00e9miov\u00fdch zna\u010dek – Michelin, Goodyear, Pirelli, Hankook, Vredestein a Nokian. V\u00fdsledky nov\u00fdch dez\u00e9n\u016f najdete zde<\/a>, t\u011bmi se ji\u017e d\u00e1le v textu nebudu zab\u00fdvat. Z nam\u011b\u0159en\u00fdch hodnot lze jednozna\u010dn\u011b vy\u010d\u00edst, \u017ee se pr\u016fm\u011br vlastnost\u00ed pneumatik s jejich sj\u00ed\u017ed\u011bn\u00edm zhor\u0161uj\u00ed. Ni\u017e\u0161\u00ed vzorek sice pom\u016f\u017ee na suchu, nicm\u00e9n\u011b v kritick\u00fdch situac\u00edch, jako je aquaplaning, kde jsou kvality pneumatik pot\u0159ebn\u00e9 nejv\u00edce se u v\u0161ech zastoupen\u00fdch model\u016f vlastnosti z\u00e1sadn\u011b zhor\u0161ili. Nutno v\u0161ak podotknout, \u017ee pom\u011brn\u011b – pneumatiky, kter\u00e9 byly s pln\u00fdm dez\u00e9nem nadpr\u016fm\u011brn\u00e9 se po ojet\u00ed vyrovnali pneumatik\u00e1m nov\u00fdm pr\u016fm\u011brn\u00fdm atd.<\/p>\n

N\u011bkter\u00e9 \u010desk\u00e9 port\u00e1ly tak z testu usoudili to, \u017ee z\u00e1konn\u00fd limit 4mm pro zimn\u00ed pneumatiky je zbyte\u010dn\u00fd. To si osobn\u011b nemysl\u00edm a v testu to nezmi\u0148uje ani Autobild, kter\u00fd cel\u00fd test vytvo\u0159il. Kdy\u017e toti\u017e vezmeme nap\u0159\u00edklad pneumatiku od Vredesteinu, kter\u00e1 nov\u00e1 na sn\u011bhu vykazuje uch\u00e1zej\u00edc\u00ed hodnoty (2+ trakce, 1- brzd\u011bn\u00ed, 2- handling a slalom), tak p\u0159i sjet\u00ed na 4mm jsou zn\u00e1mky v\u017edy minim\u00e1ln\u011b o stupe\u0148 hor\u0161\u00ed a p\u0159i 2mm je nejlep\u0161\u00ed zn\u00e1mka 4 a u brzd\u011bn\u00ed a handlingu se dostaneme dokonce na “5+”. V re\u00e1ln\u00fdch \u010d\u00edslech to tedy znamen\u00e1 o v\u00edce ne\u017e 10metr\u016f del\u0161\u00ed brzdnou dr\u00e1hu z 50km\/h na sn\u011bhu.\u00a0<\/strong><\/p>\n

To sam\u00e9 lze pozorovat bez v\u00fdjimky u v\u0161ech testovan\u00fdch model\u016f v p\u0159\u00edpad\u011b aquaplaningu – zat\u00edmco nov\u00e1 pneumatika nedostala hor\u0161\u00ed zn\u00e1mku ne\u017e 2-, u 4mm pneumatik je nejlep\u0161\u00ed trojka a u 2mm pak dokonce 4+. Argumentovat j\u00edzdou na such\u00e9 vozovce v tomto p\u0159\u00edpad\u011b nen\u00ed vhodn\u00e9 – to, \u017ee na sucho nepot\u0159ebujeme dobr\u00fd dez\u00e9n je v na\u0161em klimatu, kde pom\u011brn\u011b dost pr\u0161\u00ed bezp\u0159edm\u011btn\u00e9. Dost podobn\u011b je tomu na sn\u011bhu – u v\u0161ech pneumatik se v\u0161echny hodnoty zhor\u0161ily a kdy\u017e si p\u0159edstav\u00edm kritick\u00e9 situace p\u0159i \u0159\u00edzen\u00ed v zim\u011b, tak zde m\u016f\u017ee b\u00fdt i t\u011bch 15% brzdn\u00e9 dr\u00e1hy, o kter\u00e9 se zhor\u0161ila nejlep\u0161\u00ed pneumatika d\u016fvodem nehody, nato\u017e pak zmi\u0148ovan\u00fdch 10 metr\u016f.<\/p>\n

Pom\u011brn\u00e9 zhor\u0161en\u00ed nov\u00fdch vs. ojet\u00fdch pneumatik:<\/h4>\n

    Z m\u00e9ho pohledu je tak sp\u00ed\u0161e nevhodn\u011b n\u00edzk\u00fd letn\u00ed limit 1,6mm, kdy pneumatika s t\u00edmto vzorkem nem\u00e1 \u0161anci aquaplaningu zabr\u00e1nit, co\u017e je podlo\u017een\u00e9 i zmi\u0148ovan\u00fdm testem.<\/p>\n
