He mea ka pā ki ngā kaipupuri waka katoa te whakawhiti potae ina whakamahi ana i ā rātou waka. He mahi tiaki waka noa tēnei, engari he mea tino nui mō te haumaru o tā tātou taraiwa.

Nā, he aha ngā mea hei aro atu māu ina whakawhiti potae kia kore ai e raru? Me kōrero tātou mō ētahi aratohu mō te whakawhiti potae.

1. Kaua e hē te rahi o te potae

Ko te whakaū i te rahi o te potae te taahiraa tuatahi ki te mahi. Kei te taha o te potae ngā tawhā motuhake o tēnei potae kua whakairohia. Ka taea e koe te whiriwhiri i tētahi potae hou o te rahi ōrite i runga i ngā tawhā kei runga i te potae taketake.

Ko ngā potae radial te tikanga he potae radial. Ko ngā whakaritenga o ngā potae radial ko te whānui, te ōwehenga āhua, te diameter o roto me te tohu tere tere.

Hei tauira, tirohia te whakaahua i runga ake nei. Ko te rahi o te potae he 195/55 R16 87V, ko te whānui i waenganui i ngā taha e rua o te potae he 195 mm, ko te 55 te ōwehenga āhua, ā, ko te kupu "R" he RADIAL, ko te tikanga he potae radial. Ko te 16 te whānui o roto o te potae, e inehia ana i roto i ngā inihi. Ko te 87 te tohu o te kaha kawenga potae, he rite ki te 1201 pauna. Ko ētahi potae he tohu tere tere, mā te whakamahi i te P, R, S, T, H, V, Z me ētahi atu reta hei tohu i ia uara tere tere. Ko te tikanga o te V ko te tere mōrahi he 240km/h (150MPH)

2. Tāutahia te Tāia kia Tika

I ēnei rā, he maha ngā tauira potae he kore taurite, he ahunga rānei. Nō reira, he raruraru te ahunga i te wā e tāuta ana i ngā potae. Hei tauira, ka wehea te potae kore taurite ki ngā tauira o roto me ngā tauira o waho, nō reira, ki te hurihia ngā taha o roto me waho, kāore te mahi a te potae i te tino pai.

Hei tāpiritanga, he kotahi te arataki o ētahi potae – arā, kua tohua te ahunga hurihuri. Ki te whakahurihia te tāutanga, kāore pea he raruraru mēnā ka whakatuwheratia noa, engari ki te mea he repo, kāore e taea e tana mahi rerenga wai te mahi katoa. Ki te whakamahi te potae i te tauira ōrite, kāore hoki he arataki kotahi, kāore koe e hiahia ki te whakaaro ki roto, ki waho hoki, tāuta noa i te wā e pai ai.

3. Me ōrite ngā tauira o ngā potae katoa?

I te nuinga o te wā ka tūtaki tātou ki tēnei āhuatanga e hiahiatia ana kia whakakapia tētahi o ngā potae, engari kāore e hiahiatia kia whakakapia ngā potae e toru. Kātahi ka pātai tetahi, "Mēnā he rerekē te tauira o taku potae e hiahiatia ana kia whakakapia i ngā potae e toru, ka pāngia te taraiwa?"
I te nuinga o te wā, mēnā he rite tonu te taumata o te pupuri (arā, te kukume) o te potae ka whakawhitia e koe ki tō potae taketake, he nui te tūponotanga kāore he pānga. Engari kotahi te mea hei mōhio, i te wā ua, he rerekē te kaha o te waikeri o ngā potae me ngā tauira rerekē, ā, he rerekē hoki te pupuri i te whenua mākū. Nō reira, ki te mea kei te pēhi koe i te motuka, tera pea ka rerekē te pupuri o ō wira maui me matau. Nō reira, me roa ake pea te tawhiti pēhi i ngā rā ua.

4. He hē te āhua o te urungi i muri i te whakawhiti potae?

E whakaaro ana ētahi ka māmā haere te ahua o te urungi i muri i te whakawhiti i ngā potae. He aha te raru?
Kāore rawa! Nā te mea he maeneene tonu te mata o te potae ina whakamahia noa te potae, kāore e nui te pānga ki te rori, nō reira kāore e nui te ātete o te urungi e peia ana e tātou. Engari ina whakamahia tō potae, ā, kua memeha haere tōna papa, ka piri haere tōna pānga ki te rori, ā, ka hoki mai te āhua o te urungi.

5. He mea nui te pēhanga tika o te potae

E mōhio ana tātou, ko te iti o te pēhanga o te potae, ka nui ake te whakamarie o te haerenga; ko te teitei ake o te pēhanga o te potae, ka nui ake te pūkeko. Tērā anō ētahi e manukanuka ana ka poka te motuka mēnā he nui rawa te pēhanga o te potae, engari ko te mea pono, e whakaatu ana ngā āhuatanga katoa mēnā ka poka te motuka nā te pēhanga o te potae, he iti rawa te pēhanga o te potae, kāore i te tino teitei. Nā te mea ko te pēhanga ka taea e te potae o te motuka te tu atu i te toru hauhautanga ki runga, ahakoa ka eke koe ki te 2.4-2.5bar, ki te 3.0bar rānei, e kore te potae e pupuhi.
Mō te taraiwa tāone whānui, ko te pēhanga potae e taunakitia ana kei waenga i te 2.2-2.4bar. Mena me taraiwa koe i te huarahi nui, ā, e tika ana kia tere te tere, ka taea e koe te eke ki te 2.4-2.5bar i te āhua makariri o te potae, kia kore ai koe e manukanuka ki te iti o te pēhanga potae me te poka i te tere nui.
