Amota simbi vhiriisimbi yakaita sedhiramu, yakasungirirwa nepakati chikamu chevhiri chinotsigira vhiri mukati meprofile. Iyo inozivikanwawo semarimu, marimu, mavhiri, mabhero ematayi. Hub zvichienderana nedhayamita, hupamhi, nzira dzekuumba, mhando dzakasiyana dzezvinhu. Hub size ndiyo dhayamita yehubhu, tinowanzonzwa vanhu vachiti iyo 15-inch hub, 16-inch hub chirevo chakadaro, icho 15,16 inches inoreva saizi yehubhu. Kazhinji mumotokari, kana saizi yehubhu yevhiri yakakura uye chiyero chakafuratira chevhiri chakakwira, inogona kutamba yakanaka kwazvo yekunetsana pachiratidzo, uye kugadzikana kwekutonga kwemotokari kuchawedzerwa, asi ipapo pane matambudziko akawedzerwa ekuwedzera kushandiswa kwemafuta. Kune akawanda makuru ma paramita mu vhiri machining, mukugadzirisa kunofanirwa kutarisisa kudzora ma paramita mune inonzwisisika renji, zvikasadaro zvinokanganisa chimiro nekuita kweiyo.Simbi Rim Wheel.
