The South American circuit is a challenge to riders, teams, bikes and especially tyres, as the high temperatures and the abrasiveness of the asphalt makes this one of the most demanding tracks of the year. This will be further heightened this season because parts of the 4,806m circuit have been resurfaced, meaning Michelin and the teams have no data to process as to the type of surface and the difference it will make to one of the toughest laps on the calendar. Due to this change the MICHELIN Power Slick allocation will be slightly different from the normal three front and three rear tyres, as a fourth choice will be added to the selection. This will make the following selections available; soft, two medium and a hard compound for both the front and rear, with the two front mediums having different compounds, whilst the two rear mediums will have different casings from each other. The tyres will mostly be of a symmetrical design, with only the rear hard compound featuring an asymmetrical build with a harder right-hand shoulder. Michelinsupplies these different applications to give the riders as much choice as possible and allow them optimum performance around the Termas track.
