I fitted a pair of these to my smart fortwo rear wheels only, unfortunately kleber doesnt make 175/55/R15 yet, but as soon as they do i will probably buy a pair. the tyres worked just as good as my continental winter contacts fitted on my BMW, and perform just as good, quality grip in snow and ice and the cars DSC worked really well with the tyres. the car was pretty much undriveable with summer tyres fitted to the smart car in snowy conditions. a very good purchase for any rear wheel drive car.
