MotoGP spec-tyre supplier Brigestone will take an additional front tyre option to his weekend’s Argentina round in order to deal with ‘potentially variable track conditions;.

The Termas de Río Hondo circuit’s surface is very abrasive but with only a handful of riders turning in laps during a test last year, Bridgestone only have their best guess as to what will work so are taking harder rubber compounds.

“The Autodromo Termas de Rio Hondo is a new addition to the MotoGP in 2014, and our test at the circuit last year shows it is one of the harshest circuits on the calendar for tyres. This circuit has a high average speed with some sections featuring high-camber angles, while corners like turn six are large radius, high-speed corners that generate very high tyre loads,” said motorsport manager Shinji Aoki.

“The circuit is interesting in that although there are nine right-handed corners compared to five left-handed corners, the left shoulder of the tyre experiences higher temperatures than the right shoulder, due to the left-handers generally being faster, more demanding corners. As we have limited data for this track, we have decided to have a special allocation for the front tyres this weekend to ensure maximum safety for the riders.

“Both our front and rear tyre allocation for this race has to provide high levels of durability, stability and resistance to overheating, so we will provide tyres formulated from our harder rubber compounds for the Argentina Grand Prix.”
