G'day there,
I went with my Smart forfour for my WOF yesterday and got it with flying colours, as she has now done 97000km, i thought they might find something wrong here or there but no, even the tires were ok but the left front is down to 3mm and will get replaced in the near future together with the right front one and i like to go to 195/55R15, as they are just that little bigger and fill the wheel arches a bit nicer to my liking, but i will compare the price difference between the 195/50R15 and the 195/55R15 tires, it will also correct the speedo a bit more to the correct speed.
Greetings,
Eddie.
