Ngenxa yokuthi amathayi afundekayo akhiqizwa ngokujula okuhlukene kokunyathela,ithayiAma-stud akhiqizwa ngobude obuhlukene okumele buhambisane nokujula kwemigodi ebunjiwe ethayini (bheka umfanekiso ongezansi).IOsayizi be-stud babonakala ngenombolo yabo ye-Tire Stud Manufacture Index (FTS) yobude be-stud bubonke ngamamilimitha (mm).Izigxobo Zamathayi Emoto nikeza amathayi ukuqina okuhle.Njengoba amathayi afakwe izikhonkwane eqhutshwa ebusika,I-Carbideithayiizipikilizenzelwe ukuguga ngesivinini esifana nerabha ye-tread kanye namaphini e-tungsten carbide agqoka kancane kunezinsika zensimbi ezizungezile. Lokhu kugcina ukusebenza kwe-stud ukuqhubeka nokugxuma eqhweni njengoba ithayi liguga. Kodwa-ke, njengawo wonke amathayi, uma amathayi ahlanganisiwe eguga aze afike cishe ku-5/32" wokujula kwe-tread esele, azolahlekelwa ukusebenza kahle eqhweni elijulile futhi kufanele kufakwe isethi entsha yamathayi uma ukushayela eqhweni elijulile kusalindelwe.
