Monogram Cord and Lincoln tire dimensions

Hi;

 I believe they are representations of the 24x 8.75  white wall B.F.Goodrich tyres .

The Monogram 1941 Lincoln Continental tires are

I.D. .75 inches or 19mm 

O.D. 1.25 inches or 32 mm

Width .30 inches or 8 mm

White walls are

I.D.  .75 inches or 19mms

O.D. 1.0 inches or 27mms

The measurements aren't perfect but should be very close. I hope this helps.

Hi;

 I got this from just my tape measure and a newly delivered kit . Tire thickness ( widest point 5/16 )  Tire thickness at rim 3/16" , Tire inner Diameter ( At Rim )13/16" Tire outer outer dimension 1-3/8" . This translates to the Lincoln  and the Cord as well . O.C.G.
