Russ..............in case you didn't know, a trailer tire is not the same as a car/truck tire - something about being dragged sideways when turning. Just FYI

Thanks John,
Yep I know, The trailer tires seem to be hard as rocks,not much flex in them.

Trailer tires are more stable when the trailer is loaded. No flex. Helps eliminate some of the "sway" at speed when loaded. Joe
