Ukuhlolwa kwesondo lasebusika, ukuhlolwa kwesikhathi eside (isilinganiso sokugqoka ngemva kuka-6.000 km)

En ActualidadmotorPlay senza eyodwa ukuhlolwa kwesikhathi eside ngamathayi asebusika. Kade sino-6.000 km ne I-Michelin Primacy Alpine ngesilinganiso 205/45/17, sekuyisikhathi sokuphindaphinda imizwa esihlangabezene nayo, ukuziphatha ngokujwayelekile kwesondo nokuma ukuze senze isilinganiso sethu sokuqala sokuguga.

Ukuzwa kwami ​​ukushayela endaweni eyomile

En ukushayela emhlabathini owomile nikeza ukusebenza okuhle into embi kunesondo elihle lasehlobo, kodwa ngenzuzo ukuthi ukubamba kwayo akuncikile kangako ekushiseni. Enye inzuzo engiyitholile nge isondo lasebusika ukuthi inikeza okuningi ukuphepha okwengeziwe lapho ushayela emigwaqweni enendawo eshintshayo: Isibonelo, ukujikeleza ngokugcwele ubusika emgwaqeni owomile ngokuphelele, kungazelelwe ngemva kwejika kuvela ithunzi elivamile lapho ilanga lingashayi khona. Umgwaqo umanzi futhi uyashelela, kodwa amathayi asebusika awezwa neze ukushintsha phakathi kwenhlabathi eyomile nemanzi.

Izinzuzo ezinikezwa isondo lasebusika ngesimo sezulu esijwayelekile (15ºC) sifana kakhulu nalezo ezitholakala emazingeni okushisa abandayo (phakathi kuka-0 no-4ºC), okusho ukuthi, silandelana kakhulu futhi siyathuthuka. Ngakolunye uhlangothi, isondo lasehlobo liyawubonisa lo mehluko ezingeni lokushisa (kusuka ku-15 ukuya ku-0ºC), lishintsha indlela eliziphatha ngayo nokubamba kwalo.

Ngokuqapha, i isondo lasehlobo izosebenza kahle ukusuka ku-7ºC kuya phezulu, kuyilapho i- isondo lasebusikaikhuphuka ngaphezu kuka-14ºC, isuka emazingeni okushisa okusetshenziswa futhi ngeke inikeze isibambiso esifanayo kunesondo lasehlobo.

Ukushayela emhlabathini omanzi

Namuhla isibhakabhaka ukunika imvula echichimayo. Kusobala ukuthi kade linetha ubusuku bonke yize nginganakile. I-thermometer emotweni yami ifundeka ku-5ºC njengoba ngiphumela emgwaqweni wesibili. Ngithatha ithuba lokuthi ngiye kwelinye ukwehla kwedolobha ukunamathisela izitobhi ezimbalwa zokuma kungazelelwe ezimpambanweni zabahamba ngezinyawo... kuhle ukubona ukuthi isiliphu sezimpawu zomgwaqo kancane kancane kumanzi uma ugqoka amathayi ebusika. Noma kunjalo, kuyangibangela amahloni ukuthi lo pende ungaba yingozi kangakanani (futhi ngokwazi kwami, amabhayisikili awanawo amathayi asebusika).

ngiyaphuma ngiye umgwaqo omncane lapho ama-puddles amaningi angamukela futhi itiyela elingapheli kahle, naphezu kweqiniso lokuthi lo mgwaqo walungiswa eminyakeni embalwa edlule. I umuzwa wokulondeka uphakeme kulokho ebengikulindele: i i-hydroplaning anyamalale ngokuphelele futhi amathayi ashiye uphawu emgwaqeni obonakala kahle esibukweni esingemuva. Abakhiqizi bamathayi bathi un ukukhathala ehlobo ingakhipha amalitha amanzi angaba ngu-15 umzuzwana ngamunye! (okungukuthi ibhakede elilodwa eligcwele ngomzuzwana). Angazi ukuthi bangakhipha malini I-Michelin Primacy Alpine engikuthwalayo, kodwa kumele kube kuningi.

Ngibhekana namakhona okuqala ngesivinini esibushelelezi futhi angiboni lutho olukhethekile. Ngiphakamisa ijubane, ngiphoqa amabhuleki kakhulu futhi kancane kancane kumajika (for ukuphepha), ephawula ngokumangazayo ukuthi akukho okukhethekile okubonakalayo. Ngokusobala lokhu enye yezinhloso zamathayi asebusika, ukukwazi ukushayela emgwaqeni obandayo nogcwele amanzi ngesivinini esikhulu esihlinzeka ngokungeziwe kokuphepha.

Ngokusho UMichelin, emhlabathini omanzi emazingeni okushisa aphansi, Ibanga lokubhuleka lisuka ku-80 km/h lingamamitha angama-34 namathayi asebusika, ngenkathi no amathayi ehlobo ukubhuleka kuyakhula kuze kufike kumamitha angama-40. Anginawo amathuluzi wokuyihlola, kodwa ngingakuqinisekisa ukuthi ingabhuleka ngokugcwele ngokuthula kwengqondo.

Ngishiya umgwaqo wesibili futhi ngithathe umgwaqo omkhulu A-62 elibangise eningizimu. Lo mgwaqo usekela isiminyaminya esikhulu kakhulu kanti ne-pavement yonakala kakhulu kwezinye izindawo, kuyilapho kunezingxenye ezisanda kubuyiselwa. Umphumela uba ukuthie ishintsha isuka ku-asphalt enhle kakhulu ene-drainage enhle iye kwenye ngokunqwabelana okukhulu kwamanzi endabeni yamamitha, njalo. Ngezikhathi ezithile, ngokuzithandela ngidlula namasondo ohlangothini lwesokudla emachibini amancane amanzi akha ngokuhambisana nomugqa oqhubekayo ohlukanisa ihlombe eliqinile, ngibheka ukumelana okuphezulu kakhulu kwe-aquaplaning.

Ukuhlwa kuyaqhubeka futhi izinga lokushisa lehle kakhulu. Ngokusobala amasondo akuwona wodwa ahlushwa imiphumela yamakhaza, kusukela inkomishi yokuncela engivame ukuyisebenzisa ukunamathisela ikhamera emotweni uma amavidiyo ashuthwayo aqinile futhi awanamatheli.. Ufuna ukwazi, akunjalo?

Ukuzwa kwami ​​ukushayela eqhweni elingashoni

Ngacabanga lokho ohambweni lwami lokuya Ama-pyrenees aseFrance ebezoyithola nieve, kodwa akubanga njalo, kuye kwadingeka ngilinde. Kungazelelwe, ngaphandle kwesixwayiso endleleni ebuya ohambweni oluya e- ingxenye esenyakatho yeLeon seliqalile ukukhithika futhi ngokushesha umgwaqo umbozwe ungqimba oluncane lweqhwa. Ithemometha manje ifunda u-2ºC futhi isembozo seqhwa singu-1cm noma ngaphansi. Kulezi zimo asikwazi ukubeka amaketanga, ngoba i-metallic ibhubhisa i-asphalt (ngakho-ke ivinjelwe) futhi izindwangu ngeke zihlale ngaphezu kwemizuzu embalwa.

Yizo lezi zikhathi lapho amathayi ebusika abeke ukumamatheka ebusweni bakho. I-grooves ejulile yomdwebo inesibopho sokukhipha iqhwa eliningi kanye lamella bamba (ngokusemandleni akho) emgwaqeni noma eqhweni elihlala kuwo. Ingxube ekhethekile ye-rubber yokunyathela isebenza kahle amazinga okushisa aphansi futhi unike amandla isondo ukuthi lisebenze ngendlela elindelekile. Lngokungafani namanje ngesondo lasehlobo liyi-ABYSSMAL, okunzima ukuchaza ngamagama. Kumane kuwumehluko phakathi kokuzama ukushayela ngokucophelela okukhulu nangesivinini esiphansi kakhulu noma ukwazi ukushayela ngendlela evamile, njalo ngesivinini esimaphakathi, ngaphandle kokukhohlwa lokho. sishayela phezu kweqhwa.

Impilo yamasondo asebusika

Amasondo I-Michelin Primacy Alpin PA3 engizigibele emotweni yami zibe zintsha umdwebo 9mm. Kufanele zisetshenziswe ku-cizimo ezimbi kakhulu baze babe no-4mm womdwebo. Ukusuka lapho kuya emkhawulweni osemthethweni (1,6 mm), amathayi aphelele Zingasetshenziswa emvuleni nakubanda, kodwa zilahlekelwa ukusebenza eqhweni naseqhweni.

Ngilinganise ukunyathela kwesondo lasehlobo elisha "elilinganayo" (I-Michelin Pilot Sport 3) futhi ijule ngo-8,2 mm. Okungukuthi, isondo lasebusika (okungenani kuleli zinga) inokujula “komthetho” okucishe kube ngu-10%. ukuguga Lokhu kufanele kusebenzele ukunxephezela ukuguga okukhulu okuthi amathayi asebusika ahlukumezeke ngokomqondo uma kuqhathaniswa nehlobo.

Igeyiji esandleni, ngikala ukuguga kwamasondo ami ngemva kokusetshenziswa okuhlukahlukene okungamakhilomitha angu-6.000:

• Amathayi angaphambili: phakathi kuka-7,6 no-7,8 mm (ama-81% asele enyathela –> 31.500 km ubude beminyaka yokuphila)

• Amathayi angemuva: 8,6mm (94% esele ukunyathela okusele–>74.000km ubude beminyaka yokuphila)

Siyakubona lokho Amasondo angaphambili aguga ngokuphindwe kabili kunamasondo angemuva, ngokwengxenye ngenxa ye ukushayela ngenkani ngaphezu kokujwayelekile engikwenzayo phakathi novivinyo lonke.

Ukucabanga ukuthi ukuhlukunyezwa kuhlala njengakuqala, amathayi angaphambili azongigcina ubusika obubili futhi amane angemuva. Kungaba okunengqondo kangakanani zungezisa, kungashiwo ukuthi amathayi amane azongigcina ubusika obubili nginamandla aphelele futhi ngisezoba nenjoloba esele ukuze ngichithe ezinye izinyanga ezimbalwa zasentwasahlobo noma zasekwindla kuze kube yilapho esegugile ngokuphelele.

Okwamanje kubonakala kuyiqiniso ukuthi amathayi asebusika ahlala cishe isikhathi eside, sizoqhubeka nokwenza amakhilomitha futhi ukulinganisa ukugqokwa.

Ukuqhubeka ...
