Yes. The Zn is that it's zinc, and FN is the profile, that is, the shape of the rim it clips to.
FN is common on Japanese cars.
Very good, it is a Toyota Venza 245-50-20 tire.
They installed qty 11 1/4 oz weights on the inner rim.
They used Force Matching, but they don’t remember the reading but it was less than 20 lbs. I used a different tire installer and a junkyard OEM rim. The same tire on my car’s alloy generated a previous force of 36 lbs.
