1) Low rolling resistance leh fuel saving: Belt layer avang hian tyre a tlak hnua crown-a tangential deformation leh relative slip chu tyre pangngai aiin a te zawk hle a, radial tire-a sidewall chu a hring a, radial deformation chu a lo dam nghal vat a ni. Heng thil pahnih hi tire chhunga a chhunga a chhe lutuk tihtlem leh rolling resistance tihtlem nan a hlawkthlak hle. Test-naah chuan radial tire-te rolling resistance chu bias tire pangngai aiin 20%{{2}%) a hniam zawk tih an finfiah a, hei hian fuel chu 5%{{4}%-in a humhim thei a ni.
2) Tread hian wear resistance tha tak a nei a, service life rei tak a nei bawk: wheel a roll chuan tire landing surface chu a chhe a, a slip bawk. Deformation hian slippage a tichak a, chu chuan tread wear a tichak a ni. Radial tire crown rigidity, deformation te te, slip awm lo tluk zet, chu bakah, crown contact area a lian a, unit pressure a tlem a, a inang tlang hle a, chuvangin tread wear a tlahniam bawk. Test-naah chuan radial tire service life chu bias tire aiin 30%-40% a sei zawk tih hmuhchhuah a ni.
3) Elasticity lian leh cushioning tha: radial tire cords te chu radial direction-a dah a nih avangin, wheel a inher chuan leia perpendicular-a tire deformation chu bias tyre aiin a lian zawk a ni. A ruang hi a nem a, a elastic bawk a, chuvang chuan car smoothness a ti tha hle. Sex a ni.
Strong puncture resistance: Radial tire hian hard belt layer a neih avangin tire crown-a puncture resistance nasa takin a tichak a, tire blowout theihna a ti tlem a, driving safety a ti tha bawk.
Large Adhesion: Radial tires hian an khalh laiin ground contact area lian zawk an nei a, chutih rual chuan belt layer hnathawh avang hian ground pressure distribution pawh a inang tlang zawk a, chu chuan adhesion a ti tha a, side slip a ti tlem bawk.

1) Sidewall hi a hring a, a crack awlsam bawk.
2) Sidewall deformation hi a lian a, lateral stability pawh a tha lo hle.
3) Radial tires siam dan tur a sang a, a man pawh a to hle.
