New standard probably explains why Keystone changed tire load range from E rated to G rated from 2014 to 2015.
Same specs from manufacturer on exact same model in one year. Same 7K axles... just increased tire size. It was a smart move on their part because E rated 10 ply tires on any size Keystone Alpine won’t cut it.
