Hubcaps are accessories designed to be mounted over the steel wheel, usually used for winter tires. Made from hard plastic (ABS), available in various colors and shapes, they help cover and conceal the appearance of the steel wheel, which is typically black and lacks design. Simoni Racing hubcaps are available with designs very similar to those of the best brand alloy wheels or original equipment on sports cars. Easy to install and remove, they allow the driver to customize the look of their vehicle in a thousand different ways, just like alloy wheels.
