What is the most common tire size for a Superbird 14 or 15

[talkiemopar]

My 6pac 4 speed came with 15 in. new.   Rick.

[62 Max]

Don't think one is more common than the other,seen a" lot" of both.

the 15" wheels look better (IMO) if that helps any!

The majority of Superbirds came with 14" wheels & tires when NEW.
The new for 1970 15x7.0" wheels and F60-15 Polyglas GT tires were OPTIONED on less than 6% of '70 Road Runners (~2250 of 38,800+ total built).

GG's 1970 US spec. Road Runner F60-15 (U84) numbers:
RM21 coupes ~ 399 (2.7%)
RM23 hardtops ~ 1823 (7.8%)
RM27 convertibles ~ 21 (3.2%)

even "if" F60-15s were 3x more popular (25%) on Superbirds than all other Road Runner hardtops, that would account for ~500 of the 15" cars 

WAG  "road Wheels" & F70-14s w/RWL was the most common wheel/tire combination on a Superbird when NEW, and the rarest ..... 15x7" body color wheels w/hub caps & F60-15s w/RWL tires.

From pictures of dealerships and lots back in the 1968-71 period, what is also apparent is the large number of mopar muscle cars delivered with whitewalls.

White walls on a Roadrunner.  You bet - here is a picture of my 1970 the day I brought it home for the dealership - with white walls.  Wish I still had that car.
