Folks, would you happen to know if the "This is a set of beautiful Dunlop 266/65R18 Winter Sport snow tires and gorgeous Star Spoke 69 wheel 18 inch OEM BMW X5 rims part no.36116752027in mint condition" will work as a set of winter tires for a 2002 4.6iS?

There is a fellow on eBay that is selling that set for about $1200 delivered, and I read in this thread that I need 255/55/18 for a set of winter tires...

So... Should I consider these wheels/tires, or should I keep looking?
