Heavy Wheels

Have you ever had to change a big wheel for example of R18 or R19 size? Yesterday I wanted to help one woman-driver of BMW 740. It is terribly heavy wheel. It is good still, that the spare wheel of her car was thin. I don’t know how a woman can change by herself a usual wheel. And what if a woman drives, for example, Toyota Land Cruiser? Interestingly, whether those who projected these cars have thought above this situation? It is clear, that women in general can’t lift such weight. But what if her mobile phone is discharged?
