In all respect Alloy Rims are better than Steel rims if they are OEM made (Not Chinese copies). The thing to be kept primarily under consideration is to avoid using unnecessarily higher rim size with shorter tyre wall which usually have higher chances of damage and also discomfort as per Pakistani road conditions which include pot holes and abundance of Cat Eyes here as well.
The OEM Alloy rims have more impact sustainability (dampening) capabilities than a steel rim and do not deform over the period of time which steel rims normally do thus needing less weight for the balancing of Tyre and hence less vibrating / no vibration / wobbling as compare to steel ones enhancing suspension components life.
Also being lighter in weight contributes to better fuel economy.
The Non Geniune Chinese Alloy rims are hard, brittle and heavy in weight then OEM Steel Rims which mostly people do not know. They are the one more prone to being cracked, chip off. More over they are Wider than OEM Alloy rim of same size which makes the tyre belly less making ride hard and creates discomfort as well as premature damage to suspension parts.......
Yes, Steel RIMS are better than Aftermarket CHINESE & TAIWAN RIMS.......it is advised to stay away to avoid premature suspension damage and compromise on ride quality.
