The difference between “old style” and “new style” is in the rim
back section design.
The top back section is “old style”. The bottom back section is “new
style”.
The top design utilizes 2 to 4 pry bar pockets formed into the back
section. These pry bar pockets are used by tire service personnel for
breaking the tire off the tire bead area during demounting. The problem
with this design is if the tire has seized up real tight, and the rim is
sufficiently fatigued, the pry bar pockets can be broken off.
The bottom design utilizes a continuous pry bar slot which goes 360
degrees around the rim. This slot is used with a hydraulic tool for
forcing the flange back and to push a mounted tire off the tire bead area
of the rim. The advantage of this design over the old design is that it
has more mass than the old style which results in a stronger rim section.
In addition tire service personal have a much greater ease of doing tire
changes utilizing the hydraulic tool.
