Amathayi asebusika azo zonke izimo zezulu
Amathrendi akamuva ekwakhiweni kwamasondo ebusika awashintshile - kufanele anikeze amabanga amafushane okubhuleka, ukubamba okuthembeke kakhulu nokubamba - kungakhathaliseki ukuthi hlobo luni lwesimo sezulu esihlangabezana nalo ethrekhi. Muva nje sibe nethuba lokwazi isondo lakamuva le-Goodyear.
Ubusika ezweni lakithi abufani nje kuphela, ngakho-ke isondo lesimanje lasebusika akumele lenze kahle hhayi kuphela eqhweni elisha noma eligcwele phama, eqhweni nasemfuleni, kodwa nasezindaweni ezimanzi nezomile. Akugcini lapho, abashayeli balindele ukuthi la mathayi anikeze izinga eliphezulu lokunethezeka okuhambisana nesitayela sabo sokushayela. Isondo kufanele lithule futhi linciphise ukusetshenziswa kukaphethiloli. Inkolelo yokuthi amasondo abanzi akufanele asetshenziswe ebusika isiyinto yesikhathi esidlule. Amathayi abanzi anezinzuzo eziningi: ukuthintana kangcono nomgwaqo, amabanga amafushane okubhuleka, ukuphatha okuzethembayo nokuzinzile nokubamba kangcono. Ngakho-ke, ukwakhiwa kwesondo elinjalo kuwumsebenzi wezobuchwepheshe wobuciko, lapho, phakathi kwezinye izinto, abaklami benyathela kanye nonjiniyela futhi banyathele ochwepheshe be-compound.
Umdondoshiya wamathayi waseMelika uGoodyear wethule isizukulwane sesishiyagalolunye sesondo lasebusika i-UltraGrip9 e-Luxembourg kubathengi baseYurophu abafuna amathayi omgwaqo aqinile. U-Fabien Cesarcon, obhekelele imikhiqizo yale nkampani eYurophu, Middle East nase-Afrika, ujabulile ngokuhlolwa kwamasondo emzileni wendawo. Idonsela ukunaka kuma-sipes nasemaphethelweni wephethini entsha eyakhiwe yi-UltraGrip9 ukuze ihambisane nokuma kobuhlalu besondo, okungukuthi indawo yokuxhumana yesondo nomgwaqo, eduze ngangokunokwenzeka. Lokhu kusho ukuthi kungakhathaliseki ukuthi lihamba kanjani, isondo lisabela ngokuzethemba lapho lishayela liqonde phambili, lapho lijika emakhoneni, nalapho libhuleka futhi ligijima ngesivinini.
I-geometry eguquguqukayo yamabhulokhi asetshenzisiwe inikeza ukuphathwa okuthembekile emgwaqeni. Inani elikhulu lezimbambo kanye nama-sipe aphezulu emabhuloki ehlombe aqinisekisa ukusebenza okungcono eqhweni, kuyilapho ukuminyana kwe-sipe ephezulu kanye nendawo ethintana nayo yesikwele ithuthukisa ukubambelela kweqhwa, kuyilapho i-hydrodynamic grooves ikhuphula ukumelana ne-hydroplaning futhi ithuthukisa ukudonsa. eqhweni elincibilikayo. Ngakolunye uhlangothi, amabhulokhi amahlombe ahlangene anobuchwepheshe be-3D BIS athuthukisa ukusebenza kwamabhuleki enkathini yemvula.
Kodwa-ke, lo mncintiswano uqaphile, futhi uMichelin wethule i-Alpin 5 njengempendulo yokuguquka kwesimo sezulu eYurophu, lapho, ngenxa yeqhwa elincane, amathayi asebusika adinga ukunikeza ukuphepha hhayi kuphela ezindaweni ezimbozwe iqhwa, kodwa futhi imigwaqo emanzi, eyomile noma eneqhwa. I-Alpin 5 ithuthukiswe kusetshenziswa iphethini yokunyathela ethuthukisiwe kanye nobuchwepheshe obuhlanganisiwe berabha ngokuphepha kwasebusika njengokuhamba phambili. Ngoba ngalesi sikhathi sonyaka, izingozi eziningi ezibangelwa ukulahleka kokudonsa ziyarekhodwa. Izibalo zibonisa ukuthi kusukela ngo-Okthoba kuya ku-Ephreli, kuphela izingozi ezi-4% ezirekhodwa lapho ushayela eqhweni, futhi ngaphezu kwakho konke, okungama-57%, endaweni eyomile. Lokhu kuwumphumela wocwaningo olwenziwa uMnyango Wokucwaninga Ngezingozi Zomgwaqo we-Technical University of Dresden Ngokutadisha imiphumela yalolu cwaningo, abaklami be-Michelin benze isondo elikwazi ukudonsa kuzo zonke izimo zasebusika. Ku-Alpin 5 uzothola ubuchwepheshe obuningi obusha, kuhlanganisa. Inhlanganisela ye-tread isebenzisa ama-elastomer asebenzayo ukuze inikeze ukubamba okungcono endaweni emanzi neqhwa ngenkathi igcina ukumelana nokuginqika okuphansi. Ukwakhiwa okusha kusekelwe kubuchwepheshe besizukulwane sesine se-Helio Compound futhi kuqukethe amafutha we-sunflower, okuvumela ukugcina izakhiwo zenjoloba nokunwebeka kwayo emazingeni okushisa aphansi.
Enye into entsha ukusetshenziswa kobuchwepheshe be-Stabili Grip, obusekelwe kuma-sipes azikhiyayo kanye nokubuyiselwa okuphumelelayo kwephethini yokunyathela ekumeni kwayo kwasekuqaleni. Amabhulokhi azikhiyayo ahlinzeka ngokuthintana kwesondo kuya phansi nokunemba okukhulu kokuqondisa (okwaziwa ngokuthi "umkhondo").
I-Alpin 5 inemisele ejulile kanye namabhulokhi okunyathela aklanywe ngokukhethekile ukuze kwakhe umphumela wekati nokukhasa endaweni yokuxhumana neqhwa. Lapho amabhlogo ebuyela esimweni sawo sasekuqaleni, imisele esemaceleni iwakhipha kahle amanzi, ngaleyo ndlela inciphisa ingozi ye-hydroplaning. Ama-sipe akunyathela isondo asebenza njengezinkulungwane zezinzipho ezincane ukuze abambe futhi abambe. Uma kuqhathaniswa nesizukulwane sangaphambilini, ukunyathela kwe-Alpin 5 kunezimbambo ezengeziwe ezingu-12%, ama-notches angu-16% ngaphezulu kanye nerabha engu-17% ngaphezulu ngokuphathelene nemigodi namashaneli.
I-Continental iphinde yethula isiphakamiso sayo saseZomowa. Lena i-WinterContactTM TS 850 P. Leli thayi lenzelwe izimoto zabagibeli ezisebenza kahle kanye nama-SUV. Ngenxa yephethini yokunyathela entsha ye-asymmetric kanye 
izixazululo zobuchwepheshe ezisetshenzisiwe, isondo liqinisekisa ukusebenza okungcono kakhulu lapho ushayela endaweni eyomile neneqhwa, ukubamba okuhle kakhulu kanye namabanga okubhuleka ancishisiwe. Isondo elisha linama-engeli aphezulu e-camber kanye nokuminyana kwe-sipe ephakeme kunangaphambili. Ukunyathela kwe-WinterContactTM TS 850 P nakho kunamabhulokhi amaningi endaweni yokunyathela okuholela ezimbambo eziningi eziphambanayo. Ama-sipes phakathi nendawo yokunyathela nangaphakathi kwesondo agcwele iqhwa elengeziwe, okwandisa ukungqubuzana nokuthuthukisa ukudonsa.
TOP inkomba
Umthengi angakwazi ukuqapha izinga lokugqoka amathayi, ngoba i-UltraGrip 9 inenkomba ekhethekile "TOP" (Tread Optimal Performance) ngesimo seqhwa. Yakhelwe ku-tread, futhi lapho ukuqina kokunyathela kwehla ku-4mm, inkomba iyanyamalala, ixwayisa abashayeli ukuthi isondo alisanconywa ukuthi lisetshenziswe ebusika futhi lidinga ukushintshwa.
Kuhle ezindaweni ezomile
Ukunethezeka nokuphepha emigwaqweni eyomile kuncike kakhulu ekuqineni kwesondo lesondo. Ukuze kuthuthukiswe le pharamitha, i-Continental ithuthukise ukwakheka kwehlombe kwangaphandle kwesondo elisha le-WinterContactTM TS 850 P. Ama-sipe ebhulokhi angaphandle esondo aklanyelwe ukukhulisa ukuqina kwebhulokhi. Lokhu kuvumela ukunyakaza kwamasondo okunembe nakakhulu ngesikhathi sokujika amakhona ngokushesha. Ngesikhathi esifanayo, ama-sipes namabhulokhi atholakala ohlangothini lwangaphakathi lwesondo naphakathi kokunyathela athuthukisa ukubamba.
