I-1. I-bias eqhelekileyo ye-bias yesakhiwo se-bias eqhelekileyo ngetyhubhu yangaphakathi. I-Bias ITire ikakhulu iquka ukunyathela, i-Ply, i-buffer ye-buffer kunye ne-bead. Iintambo ze-ply kunye ne-buffer ye-buffer ye-bias eqhelekileyo icinyiwe enye kwaye ilungiselelwe kwi-angle engaphantsi kwama-90 degrees ukuya kumgca wetayitile.
I-2. Iipiti zetayara ye-radial zicwangciswe kwi-90 degrees okanye kufutshane ne-90 degrees ngomgca wetayiri, ohambelana ne-meridian yecandelo lamavili, ngokubhekisele kwi-meridia emhlabeni, oko kubizwa ngokuba yiTireal tiar. Ngenxa yelungiselelo le-Pies, inani le-Pies le-radial amatayara anokuncitshiswa malunga ne-40% -50}} iipesenti ezithelekiswa neetayile eziqhelekileyo zekhefu. I-radial tyheli iqhagamshelwe yirabha kuphela kwindawo yolwaphulo-mthetho, ukuze ikwazi ukumelana namandla amakhulu e-Traidian enesitayile esine-meridian, i-radle ye-ralting ifana nebhanti eliphezulu kwaye akukho lula. Ungqimba lwebhanti lwenziwe ngokubanzi ngentambo yelaphu (njenge-fiber yeglasi, i-fiber ye-fiber) okanye intambo yentsimbi enamandla aphezulu kunye nengqwalaselo yentembeko ephantsi.
