WRC 2017 - The MICHELIN LTX Force S5 and H4 tires showcase their strength in Argentina

This year’s Rally Argentina produced a dramatic, atypical scenario in the hills and mountains that surround Cordoba and Villa Carlos Paz, some 700km northwest of the country’s capital, Buenos Aires. It was effectively the drivers’ first opportunity on dirt to take full advantage of the power delivered by the latest-generation World Rally Cars’, even though the conditions suffered due to persistent rain in the days that preceded the start.



After the wintry Rallye Monte-Carlo, snowy Sweden, Mexico’s high-altitude tracks and the year’s first pure asphalt skirmishes in Corsica, round five of the 2017 World Rally Championship saw crews join battle on the South American fixture’s infamous sandy-coated, hard-packed roads which are viewed my many as the some of the roughest of the season.

Despite cold starts to the day, the thermometer climbed to as high as 26°C during the day, yet the predominant tyre choice was the soft-compound option for maximum performance over the hard-packed ground exposed once the loose top-coating of sand had been swept aside by the first cars on the road. This was ideal territory for the soft-compound MICHELIN LTX Force S5 which made its competitive debut as recently as early-March’s Rally Mexico. The tread of this new tyre has effectively been modified compared with its predecessor – the LTX Force S4 – in order to cope with the higher power outputs and greater efficiency of the new cars.
