Seven to nine bar on a WR/WX.  Wear limit five bar.  Maximum difference
between highest and lowest two bar.

Nine to thirteen bar on an MB.  Wear limit eight bar.  Maximum difference
between highest and lowest 2.5 bar.

Nine to thirteen bar on an RR.  Wear limit seven bar.  Maximum difference
between highest and lowest three bar.
