Some say that the steel rims are lighter, while others claim that the aluminium rims are lighter, and the third say that the difference is minimal. Everyone is right with their own measurements. This question is specifically about 165/60 R15 as the required size; we are always interested in the weight of the complete wheels (since the tyres can also be different and sometimes only fit with aluminium rims or only with steel rims). n Tyres and can – indicate the total weight as well as – whether the rim material is steel or aluminium alloy as well as – whether it is summer or winter tyres? The exact tire and rim designations are also welcome. I know the general discussions around it and do not need any general information. So who comes with “mostly”, “usually”, and the like without reference to 165/60 R15, is a dip.
