Kubera ko amapine ashobora gupimwa akorwa afite ubujyakuzimu butandukanye,ipineIbyuma bikozwe mu burebure butandukanye bugomba kuba buhuye n'ubujyakuzimu bw'imyobo ikoze mu ipine (reba ishusho iri hepfo).ItsindaIngano z'udupira tugaragazwa n'umubare watwo w'igipimo cy'umuti w'amapine (Tire Stud Manufacturing Index - FTS) w'uburebure rusange bw'udupira muri milimetero (mm).Amapine y'imodoka guha amapine gukomera neza.Uko amapine afite ibizingo atwarwa mu gihe cy'itumba,Karubideipineimitakozagenewe kwambarwa ku gipimo nk'icya kabutura yo ku rubura, aho udupira twa karuboni twa tungsten twambara buhoro ugereranyije n'ibyuma biyikikije. Ibi bituma icyuma gikomeza gukora neza mu rubura uko ipine rigenda rishira. Ariko, kimwe n'andi mapine yose, amapine amaze kwangirika kugeza kuri 5/32" by'ubujyakuzimu busigaye bw'urubura, azatakaza ubushobozi mu rubura rwinshi kandi hagomba gushyirwaho andi mapine mashya niba hagitegerejwe ko atwara urubura rwinshi.
