ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to tires and wheels for vehicles and in particular to tires and wheels for creating the appearance of low-profile tires mounted on large-diameter wheels.
2. Description of the Related Art
In recent years, consumer demand for large-diameter vehicle wheels mounted within low-profile tires has increased dramatically. Such wheels and tires create a stylish look for the vehicle on which they are used, but they cost much more than standard-sized wheels and tires. As a consequence, large-diameter wheels and low profile tires are desired by many consumers, but are beyond the financial reach of a large segment of the market. Moreover, most companies that make wheels are set up for mass production of wheels of certain standard sizes, and have often lagged behind consumer demand in developing or re-tooling expensive equipment, including molds and casting machinery, to produce the largest wheels desired by consumers.
Some consumers who want, but cannot afford or obtain, wheels with a sufficiently large diameter mounted within low profile tires may be willing to pay an intermediate cost to make standard-sized wheels and tires take on the appearance of the more expensive (and possibly unavailable) products. Detachable wheel extensions, such as the one shown in U.S. Patent Publication No. U.S. 2002/0079735 A1, have been used to attempt to simulate the appearance of larger wheels mounted within low-profile tires. However, such extensions mask a portion of the front face of the wheel and do not provide a surface integral with the design on the face of the wheel. Thus, the attempted simulation does not have a realistic-looking appearance.
In particular, the wheel extensions of the prior art have an inner ring that is removably secured within an inside edge of the outer lip of the existing wheel using a compression fit (as with a standard hub cap). A wide outer flange is attached to the inner ring and extends radially outwardly across a portion of the outside tire wall. The wheel extensions are intended to be used with many different types of wheels having a variety of surface designs on their front faces. The outward surfaces of the inner ring and outer flange generally have a smooth, generic appearance to attempt to aesthetically interface with all of these different designs. Although outer flanges of the prior art may include a narrow, upturned lip formed along the outer diameter of the flange and/or an undulated outward surface (e.g., a smooth stair-step pattern of concentric rings), the flanges do not include protrusions, indentations, or slits on their surfaces as are commonly found on the central portion of the front face of many wheels.
The inner ring for securing the wheel extension to the wheel is generally at least about ½ inch thick around its circumference, which covers up a significant portion of the underlying wheel face. When mounted on a wheel with a 17-inch diameter, a ½-inch thick ring makes the wheel appear to be only 16-inches in diameter. This results in a reduction of the visible surface area of the wheel by well over 10 percent. In addition, the smooth outward surfaces of the inner ring and outer flange generally do not blend in well with the existing design of the wheel. Indeed, the wheel extensions of the prior art are usually easily detectable by even a casual observer, and merely give the appearance of an over-extended add-on lip covering a portion of the outer tire wall. Thus, the attempted simulation is not only ineffective, it actually creates the opposite effect. Rather than simulating a larger wheel mounted within a low profile tire, the wheel extension gives the appearance of a smaller wheel mounted on a standard tire.
Moreover, the detachability of the wheel extension gives rise to additional problems. For example, wheel extensions are generally secured to wheels by providing compressible tabs which must be pressed with a tamping force within the outer lip of a standard wheel. The tabs sometimes bend or break during installation or when the wheel strikes another object, such as a sidewalk curb, causing the wheel extension to wobble or to fall off completely when the wheel turns.
SUMMARY OF THE INVENTION
The present invention provides an improved wheel and tire for simulating the appearance of a larger-diameter wheel mounted within a low-profile tire. The wheel has an inboard side and an outboard side. The outboard side includes a wide outer flange which extends around the outer circumference of the wheel. The outer flange is preferably integral with the outboard face of the wheel and covers a substantial portion of the outboard wall of the tire within which the wheel is mounted. A design, preferably comprised of, for example, a plurality of protrusions, indentations, and slits, extends across at least a portion of the outboard face of the wheel, including the outboard face of the extended outer flange.
The improved tire of the present invention is intended to be mounted on the improved wheel of the present invention with an extended outer flange. The tire comprises an outboard tire wall, an inboard tire wall, and a tread therebetween. The outboard tire wall preferably includes a laterally extending wheel protector, a ledge, and a flange seat. The flange seat is preferably contoured to match the inner face of the outer flange of the wheel and is preferably more rigid than the remainder of the tire to prevent the tire from deflecting into the outer flange of the wheel under the load of a vehicle.
The wheel of the present invention may be mounted within a standard tire of the prior art or may be mounted within the tire of the present invention to produce a highly effective simulation of a larger-diameter wheel mounted with a low-profile tire.
