fairlane1320 Posted January 24, 2023 Share Posted January 24, 2023 I'm looking for the dimensions of AMT's PP034 Firestone Wide Oval Tires as pictured. If anyone has a set and could measure them, I'd appreciate it! Quote Link to comment Share on other sites More sharing options...

peteski Posted February 1, 2023 Share Posted February 1, 2023 I'm not a muscle car expert, but I knew (mainly from looking at various model kit tire markings over the years) that back in the day tire markings were different than they are today. Plus the different numbers were mentioned on the box. Quoting https://en.wikipedia.org/wiki/Tire_code Prior to 1964, tires were all made to a 90% aspect ratio. Tire size was specified as the tire width in inches and the diameter in inches – for example, 6.50-15. From 1965 to the early 1970s, tires were made to an 80% aspect ratio. Tire size was again specified by width in inches and diameter in inches. To differentiate from the earlier 90-ratio tires, the decimal point is usually omitted from the width – for example, 685-15 for a tire 6.85 inches wide. Starting in 1972 tires were specified by load rating, using a letter code. In practice, a higher load rating tire was also a wider tire. In this system a tire had a letter, optionally followed by "R" for radial tires, followed by the aspect ratio, a dash and the diameter – C78-15 or CR78-15 for bias and radial, respectively. Each diameter of rim had a separate sequence of load ratings; thus, a C78-14 and a C78-15 are not the same width. An aspect ratio of 78% was typical for letter-sized tires, although 70% was also common and lower profiles down to 50% were occasionally seen.

This thread is getting funny, but I remember this sticker in the glovebox of my '68 Mustang. My '68 Cougar probably had a similar one, but I don't remember.
