Early automobile tires were made entirely of natural white rubber.
However, the white rubber did not offer sufficient traction and
endurance, socarbon black was added to the rubber used for the treads.
Using carbon black only in the tread produced tires with inner and outer
sidewalls of white rubber. Later, entirely black tires became available,
the still extant white sidewalls being covered with a somewhat thin,
black colored layer of rubber. Should a black sidewall tire have been
severely scuffed against a curb, the underlying white rubber would be
revealed; it is in a similar manner that raised white letter (RWL) tires
The status of whitewall tires versus blackwall tires was originally the
reverse of what it later became, with fully black tires requiring a
greater amount of carbon black and less effort to maintain a clean
appearance these were considered the premium tire; since the black tires
first became available they were commonly fitted to many luxury cars
through the 1930s. During the late-1920s gleaming whitewalls contrasted
against darker surroundings were considered a stylish, but high-maintenance
feature. The popularity of whitewalls as an option increased during the
1930s, while automobile streamlining and skirted fenders eventually
rendered the two-sided whitewall obsolete.
The availability of whitewall tires was limited during the supply
shortages of raw materials during World War II and the Korean War.
Wide whitewall tires reached their zenith in popularity by the early-1950s.
The 1957 production version of the Cadillac Eldorado Brougham was fitted
with whitewalls that were reduced to a 1" wide stripe floating on the
tire sidewall with a black area between this stripe and the wheel rim.
The whitewall stripe width began to diminish as an attempt to reduce the
perceived height of the wheel/tire, during the decade increasingly lower
vehicle heights were in vogue.
Wide whitewalls generally fell out of favor in the U.S. by the 1962
model year. They continued as an option on the Lincoln Continental for
some time thereafter but most common were narrower 3/4"-1" stripe
whitewalls. During the mid-1960s variations on the striped whitewall
began to appear; a red/white stripe combination was offered on
Thunderbirds and other high-end Fords, and triple white stripe
variations were offered on Cadillacs, Lincolns, and Imperials. Whitewall
tires were a popular option on new cars during the 1950s and 1960s, as
well as in the replacement market.
Maintaining a clean sidewall was an issue. Some motorists added
aftermarket "curb feelers" that were attached at the bottom of the wheel
opening lip to help reduce scraping the whitewall tire against curbs.
By 1968, wide whitewall tires were no longer available on the Chevrolet
Corvette; replaced by F70xl5 bias-ply nylon cord tires with thin stripes,
either a narrow white or narrow red stripe.
The single-sided whitewall remained a desirable option through the
1970s, becoming a hallmark of "traditional luxury". In some cases,
having whitewall tires were a "must have" to get the right look on a
car; and for those who could not afford the real deal, add-ons could be
installed over the rim of the wheel that could leak if the pressure was
