2001 Infiniti QX4 Automatic 4WD with RWD bias (4WD only kicks in when rear slips)

Had to replace one tire. Should new tire be on front with open diff or rear with LSD rated around 60lb breakaway torque?

The rest of the tires have about 60% tread left. Less than 15k miles on them.

I’m thinking front but want to make sure it won’t cause pulling to one side or mess something up.

Thanks!

EDIT: I know I should do pairs. Wondering if anybody had an opinion if I just kept the one.
