SS/B and SS/A Chassis and Suspension

I would guess the wheels in the photo on the back of Judy Lily's barracuda are 10" wide.
That puts them 2" wider than the 8" wheels that were being used when the
cars were introduced. 10.50 X 15 slicks were used on the 8" wheels which were 29" dia.
Cragars for Landy and Keystones for Sox & Martin.
11.00 X 15 were commonly used on a 9" wide rim.
The Crager super tricks became available in 71 and could be had in 16" X 10" and
used 12.00 X 16 slick. The super tricks were also made in all the 15" sizes.
The axle still appears to be the stock B-body width and I would say her car may still
be on the offset hangers same as the cars were delivered.
Hard to tell if she's using 15 or 16 dia. wheels in the photo. Both were possible in 72.
