A-bodies & B-bodies had many differences - it only confuses the question

1969 Road Runner w/383
STANDARD tire was T83 F70-14 Goodyear SPEEDWAY red streak ***
OPTIONAL "no-charge" tire was T82 F70-14 Goodyear SPEEDWAY white streak ***
OPTIONAL $$ tire was T85 F70-14 Goodyear POLYGLAS red streak
included with the OPTIONAL $$ "spring special" A14/A15 package - T87 F70-14 Goodyear POLYGLAS w/RWL (OPTIONAL "no-charge" tire was T85 F70-14 Goodyear POLYGLAS red streak)

*** Firestone WIDE OVAL Deluxe Champion (non-fiberglass belted) tires were used at some plants/during some dates - these tires are NOT available in reproduction

the most correct without a broadcast sheet no-brainer is - OPTIONAL $$ tire was T85 F70-14 Goodyear POLYGLAS red streak - ALL year, ALL plants, ALL OPTIONS available w/383
