Kuba amatayara aqinileyo enziwa ngobunzulu obuhlukeneyo bokunyathela,itayaraizikhonkwane zenziwe ngobude obahlukeneyo ekufuneka zihambelane nobunzulu bemingxuma ebunjwe kwitayara (jonga kumfanekiso ongezantsi).IIisayizi ze-Stud zichongwa nge-Tire Stud Manufacture Index (FTS) inombolo yobude be-stud bubonke kwiimilimitha (mm).Izikhonkwane zeTire zemoto ukunika amatayara ukuqina kakuhle.Njengoko amatayara agayiweyo eqhutywa ebusika, iCarbideitayaraizikhonkwanezenzelwe ukunxiba ngesantya esifana nerabha yokunyathela enezikhonkwane zetungsten carbide ezinxibe kancinci kancinci kunezindlu zentsimbi ezizijikelezileyo. Oku kugcina ukusebenza kwe-stud ukuqhubeka nokungena emkhenkceni njengoko ivili linxiba. Nangona kunjalo, njengawo onke amatayara, xa amathayi agxininiswe ehla ukuya kutsho malunga ne-5/32 "yobunzulu bokunyathela obuseleyo, baya kulahlekelwa ukusebenza kakuhle kwikhephu elinzulu kwaye isethi entsha yamatayara kufuneka ifakwe ukuba ukuqhuba kwekhephu elinzulu kusalindelwe.
