Un cititor cu spirit de observatie se poate intreba pe buna dreptate,\u00a0daca este o diferenta intre pneurile\u00a0de zapada\u00a0si\u00a0pneurile de iarna?\u00a0 Buna intrebare.<\/p>\n

Si avem exemple practice\u00a0din\u00a0viata reala:\u00a0in familie\u00a0Bridgestone\u00a0Firestone,\u00a0Bridgestone\u00a0Blizzak\u00a0este anvelopa\u00a0de iarna,\u00a0Firestone Winter Force este\u00a0cauciuc de zapada, \u00a0in\u00a0familia\u00a0Michelin \/\u00a0BFG \/\u00a0Uniroyal,\u00a0 Michelin\u00a0X-Ice\u00a0este\u00a0anvelopa de iarna iar\u00a0BFGoodrich Winter Slalom\u00a0este de zapada, in\u00a0lume\u00a0Pirelli,\u00a0 Snowsport\u00a0este o anvelopa\u00a0de iarna iar\u00a0Winter Carving este un\u00a0pneu pentru zapada.\u00a0 Raspunsul vine observand evolutia anvelopelor.<\/p>\n

Pentru\u00a0o perioada mare de timp,\u00a0industria anvelopelor a functionat cu un numar limitat de standarde.\u00a0Orice companie\u00a0putea eticheta\u00a0orice pneu\u00a0asa cum dorea.\u00a0\u00a0Concurenta\u00a0 a impins companiile sa\u00a0creeze anvelope<\/a><\/span> care\u00a0sa functioneze\u00a0pe\u00a0zapada iar aceste pneuri<\/a><\/span>\u00a0pentru zapada \u00a0purtau marcajul\u00a0M\u00a0&\u00a0S. \u00a0Tractiune\u00a0pe zapada\u00a0 depinde de\u00a0mai multi factori :\u00a0flexibilitatea cauciucului,\u00a0o multime de\u00a0muchii\u00a0ascutite si de caneluri late.\u00a0 Deci,\u00a0asta este ceea ce\u00a0anvelopele de zapada arata :\u00a0blocuri mari, cu margini\u00a0patrate si canelurile late,\u00a0toate realizate\u00a0din\u00a0compusi \u00a0de cauciuc\u00a0care ramane moale la temperaturi\u00a0sub punctul de inghet.<\/p>\n

Aceste anvelope\u00a0pentru zapada\u00a0au avut o tractiune pe zapada multumitoare,\u00a0dar\u00a0punctul lor slab a fost asfaltul.\u00a0 Blocuri\u00a0patrate cu muchii ascutite\u00a0inconjurate de\u00a0caneluri late si adanci\u00a0au tendinta de a\u00a0se torsiona\u00a0mult. Din moment ce\u00a0banda de rulare\u00a0se torsioneaza,\u00a0produce caldura\u00a0si caldura cauzeaza\u00a0 degradarea pneurilor,\u00a0ele\u00a0uzandu-se repede.\u00a0\u015ei nu in ultimul rand,\u00a0au fost\u00a0zgomotoase. \u00a0In timp,\u00a0acest model\u00a0de baza\u00a0al\u00a0pneului pentru zapada\u00a0a fost imbunatatit\u00a0astfel ca\u00a0zgomotul a fost redus,\u00a0torsionarea a fost redusa,\u00a0uzura\u00a0ameliorata iar tractiunea nu a fost\u00a0diminuata.<\/p>\n

Companiile\u00a0de anvelope\u00a0au inceput sa utilizeze\u00a0noi retete pentru mixtura de cauciuc care au dus la micsorarea coeficientului de torsiune iar modelarea pe calculator,\u00a0a constatat\u00a0ca\u00a0blocurile\u00a0benzii de rulare\u00a0nu\u00a0trebuie sa fie\u00a0mari, patratoase si ur\u00e2te. Inginerii de\u00a0anvelope\u00a0au inceput\u00a0sa se refere la\u00a0cele mai bune\u00a0dintre aceste anvelope ca fiind “anvelope de iarna<\/a><\/span>,”\u00a0pentru a ajuta\u00a0sa le diferentieze\u00a0de rudele\u00a0lor\u00a0zgomotoase. Anvelopele de iarna\u00a0au fost\u00a0in mod dramatic mai bune\u00a0pe\u00a0asfalt\u00a0 decat\u00a0anvelopele pentru zapada.<\/p>\n

Apoi,\u00a0au inceput sa\u00a0fie adoptate standarde la nivel mondial.\u00a0 Orice\u00a0pneu\u00a0care trebuie sa fie conform,\u00a0 trebuie sa\u00a0aiba\u00a0logo-ul\u00a0anvelopei de iarna:\u00a0un fulg de zapada \u00a0inauntrul unui munte. \u00a0Un alt\u00a0sens bun al\u00a0 standardelor\u00a0a \u00a0fost\u00a0ca i-a inspirat\u00a0pe ingineri\u00a0 pentru a face\u00a0cele mai bune\u00a0lucruri pentru cele mai rele\u00a0conditii.\u00a0Bridgestone\u00a0a venit cu\u00a0compusul\u00a0multi-celule Blizzak, o\u00a0anvelopa\u00a0uimitoare\u00a0pe gheata, Yokohama\u00a0a ridicat stacheta cu\u00a0IG-10,\u00a0in timp ce\u00a0alte companii, cum ar \u00a0fi\u00a0Goodyear\u00a0si\u00a0Toyo\u00a0 au adaugat\u00a0 siliciu in amestecul\u00a0de cauciuc.\u00a0Michelin,\u00a0ca de obicei,\u00a0a mers pe calea ei \u015fi a produs\u00a0X-Ice,\u00a0un pneu pentru zapada\u00a0\u015fi gheata. Desigur,\u00a0toate aceste\u00a0cercetari \u015fi\u00a0tehnologii au\u00a0imbunatatit\u00a0si pneurile\u00a0de zapada.<\/p>\n

Deci, cu un pneu pentru zapada, tot veti avea\u00a0banda de rulare\u00a0groasa,\u00a0o stabilitate\u00a0ceva mai mica pe autostrada\u00a0si\u00a0mai mult zgomot,\u00a0dar\u00a0veti avea tractiune\u00a0pe zapada.<\/p>\n

Cu o\u00a0anvelopa de iarna,\u00a0aveti o plimbare\u00a0mai silentioasa,\u00a0mai putin zgomot\u00a0decat unele anvelope\u00a0all-season,\u00a0aderenta si rulaj bun pe asfalt, caracteristici de\u00a0rezistenta indelungata la uzura\u00a0\u015fi, \u00a0nu in ultimul r\u00e2nd,\u00a0tractiune buna pe gheata\u00a0\u015fi\u00a0zapada.<\/p>\n

Si avem exemple practice din viata reala: in familie Bridgestone Firestone, Bridgestone Blizzak este anvelopa de iarna, Firestone Winter Force este cauciuc de zapada, in familia Michelin \/ BFG \/ Uniroyal, Michelin X-Ice este anvelopa de iarna iar BFGoodrich Winter Slalom este de zapada, in lume Pirelli, Snowsport este o anvelopa de iarna iar Winter Carving este un pneu pentru zapada.
