I just took off a B and put a non-B on but unfortunately recycled the old already.
Both tires are 805 lbs with same load rating. Both have the LR-B
I don't see a B in a circle by the logo of the non-B
This does get confusing, this will help... the Heavier Load Rated Tire will have Three Plys as seen here:
