2 tires are from 2021 only used for roughly 4 months and then the other set are more worn and have been on the vehicle during spring/summer since 2011. All 4 are on rims, tires are 195/60 and 15 inch rims. Used on my 2003 Volvo V40. Tiger paws are the newer and the continentals are no longer sold. I got a flat and had to replace the two fronts hence the mismatch in brand. They rotated the tires at this time and moved the continentals to the front and tiger paws were on the back. All 4 are rated for mud and snow (all season)
