Bridgestone has upped the ante on the ‘street to track’ concept with the introduction of the RE-71RS.
The new street legal semi-slick promises increased grip levels, improved handling, and better wear life over its predecessor, the RE-71R, while retaining practicality for everyday use.
The Potenza RE-71RS is Bridgestone’s entry-level motorsport product, positioned above the road focussed RE003 and S007A in terms of outright dry grip, and as a street legal alternative to the track-only RE-11S product.
The RE-71RS tread pattern design boasts an 11 per cent larger contact area than its predecessor through the use of a high-grip polymer compound for exceptional grip levels in dry conditions.
The slick outer shoulder allows for maximum contact, increasing the tyre’s cornering capabilities, while two deep grooves provide high levels of water drainage to deliver strong wet performance characteristics.
Bridgestone says driver feedback is also direct because of the tyre’s rigidity, improved by the low angled grooves along the face of the tyre.
There’s an improvement of 5 per cent in wear life over the RE-71RS predecessor due to its asymmetric tread design and uniform contact pressure. The benefit extends to the road, with greater wear life and lower noise than conventional semi-slick tyres.
The company says that the Potenza has been tested extensively by Bridgestone R&D department in Japan, putting the new tyre through its paces at the Tsukuba Circuit in Japan, utilising a professional Bridgestone Motorsport test driver and a modified Subaru BRZ.
RE-71RS demonstrated an improvement to the average lap time of 1.1 per cent, with a peak lap time improvement of 2 per cent. A further 8,000km of durability testing was conducted, with tyre rotations conducted at every 2,000km to validate the 5 per cent wear life improvement in extreme conditions.
Bridgestone is launching the RE-71RS in 27 sizes ranging from 15-20 inch options, all warehoused locally.
