Ferrari experimented with their own version of the ‘extractor’-style rear wheel rims, as introduced by Mercedes at Spa last year. Holes on the inner face of the wheel align with those on the exterior to extract hot air more quickly from the wheel rim, thereby transferring less of the heat to the tyre. The nodules around the outer face of the rim add to the extractor effect and also provide a greater surface area over which to spread the heat – again reducing the heat transfer to the tyre.
