These fit a 2nd Generation Toyota Prius (2004-2009), I have a 2008. I used these last year to drive from Somerset to Fresh Pond where I work (typically putting them on in Camino). I used them about 6 times last winter. My Prius' hybrid battery took a dump and, thus, is the reason I no long need them. These are mud and snow tires with some extra studs and tire chains on them. One wheel is chromed, the other just standard aluminum.
