Whitewall tires are tires that have a stripe of white rubber on the outer sidewalls. The original whitewalls featured an entirely white sidewall. Modern whitewall tires often have a thin white stripe, or white raised lettering identifying the tire manufacturer & tire model. Such tires were made with a full strip of white rubber under the black. The raised white letters were revealed by buffing the cured tire sidewall. The black covering strip was made of Neoprene (polychloroprene) to avoid staining.

Classic vehicles have usually been optioned with wide whitewalls - it was popular during the pre & post-war era, only to resurface in the 1970s as a limosine trademark & within the pimpmobile culture. Although wide whitewalls are rare on modern automobiles, they are still manufactured by specialty outlets and/or classic car restoration companies such as Coker Tire & Vogue Tire Company. Some companies manufacture wide whitewall inserts - the Portawall inserts are usually sold through VW Beetle restoration companies.

Whitewalls were popular on classic cars, lowrider & Cadillacs. Modern trends toward more minimal styling, & large rims favoring low-profile tires leave little room for a whitewall.
