The 1969 Mustang used six different tire types, with the types based upon the original engine equipment that was ordered on each particular car. The base 6-cylinder and 302 cars used a C78x14” tire as standard equipment. An E78x14” tire could be ordered optionally on any of the 6-cylinder or 302 cars, while also being standard equipment on the 351 and 390 equipped cars. The 302, 351 and 390 equipped cars could also be ordered with an optional E70x14” Wide Oval. These E70x14” Wide Oval tires were also only available optionally on the 428 and GT Equipment Group cars. An optional F70x14” Wide Oval was again offered for 1969, this time as optional equipment on the 302, 351,390,428 and GT Equipment Group cars. The FR70x14” Wide Oval Radial ply tires made their second appearance in 1969 as optional equipment on the 302, 351,390,428 and GT Equipment Group cars. The 185-R14” Radial ply was now discontinued and a new F70x14” Fiberglas belted tire was now mandatory equipment on the 428 Cobra Jet cars. The last tire that was available on the 1969 Mustang was the F60x15” tire, which was the standard and only tire available on the Boss 302 and Boss 429 cars.
