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.
