Load index 94 winter tires in 185/60R15 are hard to find: The Nexen Euro-Win LTR 185/60R15C is the only one I found.
(spec sheet here)
Some alternatives:
Go for a lower load index tire such as 185/60R15 88 T XL (see this owner's manual supplement from Nissan). With these, payload goes down to 1200lbs.
Get a slightly bigger tire. A 195/60R15 92T XL is only 2% bigger (diameter) and is closer to the OEM load index.
