[Chrysler300]

["Rich Barber" <c300@xxxxxxx>]

Wheel data for 1955 Chryslers from the 1955 service manual:

 

Windsor, New Yorker, 300: 15 X 5.5, 4 ½ bolt circle, 5-1/2X20; 7.60?s on the
Windsor, 8.00?s on the NY & 300

 

Imperial: 15X6, 5 ½ bolt circle, 9/16 X 18; 8.20?s

 

Crown Imperial: 15X6 ½, 5 ½ bolt circle, 9/16 X 18; 8.90?s

 

All use lug bolts with LH or RH threads.

 

 

 

Observations on the wheels from my C-300:

 

There are four cooling slots @ 3.5? each at the outer edge of the center
disk

 

There are two raised nubs for anti rotation-one on each side of the valve
stem hole only  These fit into depressions in the locking tabs on the wheel
covers and the wheel covers are the same as for Imperials, but with
different plastic centers.

 

Between each pair of lug bolt holes is a smaller hole with a square
extension and a second tiny hole.  The big hole is to receive the alignment
pin on the brake drum that assists in mounting the rim and starting the lug
bolts into the threaded holes in the brake drum.  Reasons for the square
extension to the alignment holes and for the tiny holes near each alignment
hole are unclear to me.

 

Measurement from the edge of the inside rim to the inside face of the center
disc is 3 7/8?

 

 

 

Opinion:

 

Seems like Chrysler could have easily and cheaply put the Imperial or Crown
Imperial wheels and tires on the 300?s.  The 8.00?s seem a little wimpy in
appearance, but maybe Goodyear was unwilling to make the Blue Streak tires
in anything over the 8.00.

 

 

 

Question:

 

Anyone seen 8.00 X 15 bias-ply tires with 3? WSW in anything other than
Coker?s or Lucas?s General Dual 90?s?

 

 

 

C-300?ly,
