6.95x14 Firestone, BSW or WSW would be the most typical tire size, K codes would have had dual redline 6.95x14 as the base tire. A steel wheel or styled steel in the trunk would be correct. If the car was ordered from the factory with styled steel wheels, there is a high(er) chance that it had one in the trunk. If the wheels were installed by the original selling dealer when the car was new, it may or may not have come with the 5th styled steel.
