A load rating refers to a maximum allowable weight that a given wheel has been tested and rated at. All wheels can be rated differently, for instance the wheels on a
passenger car will require a smaller load rating than the wheels on a heavier SUV. A vehicle manufacturer will give a standard GVWR (Gross Vehicle Weight Rating) to
each of its vehicles. This rating is the maximum allowable weight for a fully loaded vehicle which includes passengers and extra equipment. At that point each of the
wheels is tested and rated according to the GVWR of all the vehicles they were meant to be mounted on.
The offset is a vital technical aspect of your wheel and your car. To better explain this, Cray has put together a brief 101 video on offsets. You can also go to our
wheel technology page to learn more about offsets.
The handling can be improved by running larger wheels on your Corvette. Generally larger Corvette wheels mean that you will run a lower profile tire and usually a
wider tire. The low profile tire often performs better when cornering and braking, as tire roll is greatly reduced.
Extremely large wheels are heavier and can increase braking distances. However, Cray will always endeavor to keep the wheels as light as possible without compromising the strength of the wheel.
With regular care and regular road conditions, Cray offers a one year finish warranty on its wheels with chrome and painted finishes. Cray provides a lifetime structural
warranty for wheels it manufactures that are structurally unsound because of a manufacturing defect caused by Cray that makes the wheel unfit for its ordinary purpose.
Damage or issues with wheels manufactured by Cray that are not caused by, or the result of, a manufacturing defect by Cray are not covered under the warranty. Additionally,
the following are expressly excluded from the warranty:
Cray does not offer a "road hazard warranty," so any damage or issue with a wheel caused by the wheel colliding with a pothole or any other object or debris
will not be covered by the warranty;
Wheels that have been used in racing are not covered by the warranty regardless of the damage or structural unsoundness; and
Wheels mounted on vehicles with a load rating in excess of the load rating of the wheel are not covered by the warranty regardless of the damage or structural unsoundness.
Wheels that have been modified, repainted, or powder coated.
Cray wheels are designed to fit on the Corvette C4, Corvette C5, Corvette C6, Corvette C6 Z06, Corvette C7 vehicles. Of course we always recommend test fitting for
proper fitment prior to mounting of tires, especially on heavily modified vehicles. You can also visit our vehicle fitment guide to check which wheels fit which vehicles.
