Trailer tire speed ratings are encoded.   Unless you have the proper code reader...... 
That one would be ''ST''. Let me decode:
''ST, 65mph, space shuttle weight rating, nobody cares until trailer tires explode, and then they still won't replace it with a quality tire, made in china, your kids safety isn't worth a $200 premium, RV shmucko approved, do not use if road temperatures exceed 65F, Good Sam Club seal of quality''
