The Aventador came out in 2011 as a 2012 model in the US with a standard wheel option called the Iperione Wheels. This is a paired 5 spoke design that is 19″ in the front and 20″ in the rear. It is available in a satin silver finish or painted shiny black.
For model year 13 they have released a new design that is a larger 20″/21″ size with a sharper spoke design similar to the Scorpius II design of the MY2011+ LP570. It is available in silver, shiny black, and matte titanium. Here are some pictures of the different designs.
