Whitewall tires or white sidewall (WSW) tires are tires having a stripe or entire sidewall of white rubber. These tires were most commonly used from the early 1900s to around the mid 1980s.
The use of whitewall rubber for tire has been traced to a small tire company in Chicago called Vogue Tyre and Rubber Co that made them for their horse and chauffeur drawn carriages in 1914. [1]
Early automobile tires were made of pure natural rubber with various chemicals mixed into the tread compounds to make them wear better. [2] The best of these was zinc oxide, a pure white substance that increased traction and also made the entire tire white. [2] However, the white rubber did not offer sufficient endurance, so carbon black was added to the rubber to greatly increase tread life. [3] 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 are made.[ citation needed ]
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. On 6 April 1934, Ford introduced whitewall tires as an $11.25 (equivalent to $256in 2023) option on all its new cars. [4] But automobile designs incorporating streamlining directed visual interest away from tire walls.
The availability of whitewall tires was limited in the US during the supply shortages of raw materials during World War II and the Korean War. [5]
Wide whitewall tires reached their height 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. During the 1950s, Fender skirts also covered up white wall tires. [6]
Wide whitewalls generally fell out of favor in the US 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-inch (1.9–2.5 cm) 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. 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 too high. [7]
New tires were wrapped in paper for shipping, to keep the white stripe clean, and for preventing the black of other tires from rubbing on the whitewall side. [8] 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. [9]
By 1968, wide whitewall tires were no longer available on the Chevrolet Corvette; replaced by F70x15 bias-ply nylon cord tires with thin stripes, either a narrow white or narrow red stripe. [10]
The single-sided whitewall remained a desirable option through the 1970s, becoming a hallmark of "traditional luxury". Radial tires made by Vogue Tyre featured a narrow whitewall with a thin gold stripe line toward the edge of the tire. They were most often fitted to luxury cars. [11]
Full-fledged wide whitewalls have made a return within modified car culture. The resurgence of traditional hot rods, customs, retro, lowriders and resto-cal cars have also contributed to the resurgence in whitewall tires.
Although wide whitewalls are virtually nonexistent as a factory option on modern automobiles, they are still manufactured in original bias-ply or radial form by specialty outlets such as Coker Tire and Vogue Tyre. The last car available in the United Kingdom with whitewall tires was the Kia Pride. Some companies manufacture wide whitewall inserts - the so-called "Portawall" inserts are usually sold through Volkswagen Beetle restoration companies. Another modern incarnation has been tire decals, which can be applied to a normal tire to give the whitewall look.
Modern trends toward more minimal styling, and large wheels favoring very low-profile tires leave little room for a whitewall. The Lincoln Town Car continued to be offered with a factory whitewall option—a narrow white stripe—until its discontinuation in 2010. It is not currently offered as a factory option by any car manufacturer, but it is possible to order whitewalls for motorcycles (for example, the 2014–present Indian Chief).
A tire is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, providing a flexible cushion that absorbs shock as the tire rolls over rough features on the surface. Tires provide a footprint, called a contact patch, designed to match the vehicle's weight and the bearing on the surface that it rolls over by exerting a pressure that will avoid deforming the surface.
The Continental Mark V is a personal luxury coupe marketed in North America by the Lincoln division of Ford Motor Company for model years 1977–1979. It was the third generation of the Mark Series that first began with the 1969 Continental Mark III. At 230 inches (5.8 m) in length, it was the longest two-door coupe Ford has ever marketed.
A racing slick or slick tyre is a type of tyre that has a smooth tread used mostly in auto racing. The first production slick tyre was developed by M&H Tires in the early 1950s for use in drag racing. By eliminating any grooves cut into the tread, such tyres provide the largest possible contact patch to the road, and maximize dry traction for any given tyre dimension. Slick tyres are used on race tracks and in road racing, where acceleration, steering and braking require maximum traction from each wheel. Slick tyres are typically used on only the driven (powered) wheels in drag racing, where the only concern is maximum traction to put power to the ground, and are not used in rallying.
Tire rotation is the practice of moving the wheels and tires of an automobile from one position to another, to ensure even tire wear. Even tire wear extends the useful life of a set of tires, but the value of this is disputed.
A radial tire is a particular design of vehicular tire. In this design, the cord plies are arranged at 90 degrees to the direction of travel, or radially. Radial tire construction climbed to 100% market share in North America following Consumer Reports finding the superiority of the radial design in 1968, and were standard by 1976.
The spinner on automobile wheels historically refers to knock-off hub nuts or center caps. They may be the actual, or intended to simulate, the design used on antique vehicles or vintage sports cars. A "spinner wheel" in contemporary usage is a type of hubcap or inner wheel ornament, that spins independently inside of a wheel itself when the vehicle is in motion and continues to spin once the vehicle has come to a stop.
The rim is the "outer edge of a wheel, holding the tire". It makes up the outer circular design of the wheel on which the inside edge of the tire is mounted on vehicles such as automobiles. For example, on a bicycle wheel the rim is a large hoop attached to the outer ends of the spokes of the wheel that holds the tire and tube. In cross-section, the rim is deep in the center and shallow at the outer edges, thus forming a "U" shape that supports the bead of the tire casing.
Automotive tires are described by several alphanumeric tire codes or tyre codes, which are generally molded into the sidewall of the tire. These codes specify the dimensions of the tire and its key limitations, such as load-bearing ability and maximum speed. Sometimes the inner sidewall contains information not included on the outer sidewall, and vice versa.
Plus sizing is the practice of replacing an automotive wheel with one of a larger diameter fitted with a new tire of lower aspect ratio so that the new tire has close to the same diameter and circumference as the original tire to minimize any changes in speedometer accuracy, torque and traction control, while reducing sidewall flex and (generally) increasing cornering ability.
Fender is the American English term for the part of an automobile, motorcycle or other vehicle body that frames a wheel well. Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface.
The Goodyear Polyglas tire was a bias-belted tire announced in 1967 by Goodyear. "Polyglas" was a registered trademark. The tire combined some characteristics of both bias-ply and radial-ply tires. They had a wider tread than most other tires on the market then and used fiberglass belts.
Coker Tire Company is a Chattanooga, Tennessee-based company that manufactures and sells vintage-style Michelin, Firestone, BF Goodrich and Uniroyal bias-ply and radial whitewall tires for collector automobiles. The company was originally a tire and service center founded in 1958 by Harold Coker. He would later give his son Corky Coker the opportunity to manage the antique division, which was a small percentage of the company's earnings. Corky devoted 40 years to growing the antique division of the business, eventually making it the company's primary focus. Corky retired in 2014, and he appointed Wade Kawasaki as President to oversee the operations of six companies and numerous brands under the Coker Group. In November 2018, Corky sold Coker Tire and its parent company, Coker Group, to Irving Place Capital.
A continental tire or a continental kit is the common U.S. term for an upright externally-mounted spare tire behind an automobile's trunk.
Kustoms are modified cars from the 1930s to the early 1960s, done in the customizing styles of that time period. The usage of a "K" for "Kustom" rather than a "C", is believed to have originated with George Barris.
A spare tire is an additional tire carried in a motor vehicle as a replacement for one that goes flat, has a blowout, or has another emergency. Spare tire is generally a misnomer, as almost all vehicles actually carry an entire wheel with a tire mounted on it as a spare rather than just a tire, as fitting a tire to a wheel would require a motorist to carry additional, specialized equipment. However, some spare tires are not meant to be driven long distances. Space-savers have a maximum speed of around 50 mph (80 km/h).
Formula One tyres are specialised racing tyres designed for use on a Formula One car. Tyres play a crucial role in the car's performance, affecting grip, handling, and overall speed. Tyres are also a component into racing strategy, depending on factors such as weather or deterioration. Throughout the history of Formula One, tyres have undergone major changes with different manufacturers and specifications used in the sport. Since 2011, tyres have been provided exclusively by Pirelli, an Italian tyre manufacturer. As of the 2024 season, there are 8 separate types of tyres available for use during events.
A bicycle tire is a tire that fits on the wheel of a bicycle or similar vehicle. These tires may also be used on tricycles, wheelchairs, and handcycles, frequently for racing. Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and braking. Although the use of a pneumatic tire greatly reduces rolling resistance compared to the use of a rigid wheel or solid tire, the tires are still typically the second largest source, after wind resistance, of power consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle.
The Michelin PAX is an automobile run-flat tire system that utilizes a special type of rim and tire to allow temporary use of a wheel if its tire is punctured. The core of Michelin's PAX system is the semi-rigid ring installed onto the rim using special equipment. It provides support to the tire and its sidewall to allow emergency operation at limited speed until such time as the tire can be replaced. Cars that use the system include supercars like the Bugatti Veyron EB 16.4, luxury cars like the Rolls-Royce Phantom, and more common vehicles like the Honda Odyssey and Nissan Quest.
Vogue Tyre and Rubber Co., also known as Vogue Tyre, is an American company providing custom luxury tires, wheels, and car accessories. The company was founded in 1914 in Chicago, Illinois by Harry Hower and then in 1940, sold to Lloyd O. Dodson who remained its chairman until his death in March 1996. Vogue Tyre invented the whitewall and patented the gold stripe in the 1960s.
Tire lettering is the practice of putting, or drawing visible letters on the sidewall of an automobile's tires. In modern usage, the lettering is often big car brands or tire brands names, with custom lettering being a much smaller niche of that. It can also refer to other after market customizations to the side wall of the tire, such as the "white wall tire" look, but any color of the spectrum is available now, including "rainbow wall tires".
