Diameter: .7035" or 17.9 mm

Width: 0.2435" or 6.19 mm

Normal 17" diameter x 6" wide wheel at 1:24 scale (Exact = 16.88" D x 5.88" W).

I have selected several sets of tires from various 1/24 scale kits by Model Factory Hiro and Profil24 to see how they fit. Those tires were intended for 16" diameter applications for Ferrari, Aston Martin, and Maserati. The fit was snug, but worked surprisingly well despite the slight difference in scale diameter. If you prefer to use them for exact scale applications, you can visit the Borrani Americas website where you will find a product listing for more wire wheels, with complete dimensions, as used on most of the popular sports racing cars from the 1930's to 1960's.
