Hello, I have recently called a Smart ForTwo Cabrio my own. It stands on the front: 145/65/R15(Maxxis all-year tire) rear: 175/55/R15(Maxxis all-year tire) and drives cruelly. It pushes like sow over the front wheels and is always slipping when braking. Since I don’t really think of all-year tires, I would like to have very good winter tires including matching rims now. Through the search I have already found some information, which is not sufficient for me as a Smart newcomer, however, because there is always talk of 175 and 195. Sometimes the 195 with 50s height and sometimes not, then one reads something about 195/45/15…. The rims of 451 seem to not to fit because of the ET, but it should also be with track widenings here. :S Can’t even be so nice to one of them and make a complete listing, which wheel/tire combis fit on the 450s. From me also with indication of the corresponding lane widths. I would like to have a ride on the front axle or the best of the front axle. I would like to be happy.
