Hi Everyone. I'm looking to buy some 19 inch snow tires for my 2013 p85. I see a pretty good deal on 2 used Pirelli Winter Sottozero 3 tires, and 2 used Pirelli Winter Sottozero series II tires. They all have about the same tread left of 7/32. Do you think this would cause any issues or should all 4 tires be the exact same tires? Thanks!
