I use 185/60R15's for my snow tires. Other than the superior traction in the winter I have not noticed any differences in my C's handling. Of course MPG's go down with the winter tires for a multitude of reasons. My regular tires are 175/65R15 as was fitted on the C2 when bought new. The next time I buy regular tires I would definitely consider 185/60R15's unless my tire guy gave me a good reason not to use them.
