The Ultrac Vorti R is Vredestein’s most sporty Ultra High Performance summer tyre to date. Compared to the Ultrac Vorti, the emphasis with the Ultrac Vorti R lies with ensuring grip and driving precision for the most powerful cars. The tyre maintains its traction at higher temperatures, including on bends, and is exceptionally stable at high speeds. It is therefore the ideal partner for four-wheel and rear-wheel drive sports cars that demand the most from their tyres.

The Ultrac Vorti R was developed in close cooperation with Italian design company Giugiaro, and the carbon accents on the sidewall and in the tread are a design feature unique to this tyre. It is available in several sizes that have been specifically optimised for the rear axle. They include an adjusted belt angle and an even lower air ratio, with an increased focus on maintaining grip on dry surfaces (as the front tyres discharge most of the water on wet roads).

 EU Tyre Label and Efficiency Classes

EU Tyre Label and Efficiency Classes

The European Union has introduced the EU Tyre Label by Regulation (No. 1222/2009) identically and bindingly for all EU member states. It applies to passenger car tyres, light commercial vehicle tyres and heavy commercial vehicle tyres produced after 01.07.2012.

Three different areas are tested: rolling resistance, wet grip and the rolling noise the tyre makes on the road.

The following are not affected by the EU Tyre Label: retreaded tyres, professional off-road tyres, racing tyres, tyres with additional devices to improve traction such as spiked tyres, T-type emergency tyres, special tyres for fitting to vehicles first registered before 1 October 1990, tyres with a maximum authorised speed of 80 km/h, tyres for rims with a nominal diameter of 254 mm or less or 635 mm or more.

With this regulation, the European Union is pursuing the goal of promoting economic and ecological efficiency in road traffic as well as increasing road safety on the one hand, and on the other hand, granting consumers more product transparency and at the same time serving as an active decision-making aid.

Already during the incorporation, experts criticise the fact that the EU Tyre Label unfortunately only shows a few product characteristics. Apart from rolling resistance, wet grip and rolling noise, which are the main focus of EU tyre labelling, tyres have much more important and safety-relevant product characteristics, such as aquaplaning properties, driving stability, service life, braking properties on dry and wet roads, behaviour in wintry conditions, etc.

Tyre manufacturers point out that test results from various institutions and journals remain an important information medium for the end consumer. These tests usually focus on further safety-relevant product characteristics besides the EU standard qualifications for tyre labelling, which are always important for the final customer.

I cannot really rate the tyres accurately as I do such a small mileage and drive very carefully to preserve the value of the vehicle. I bought them for the economical price though by the time my nominated fitter had added £30/tyre, I'm not convinced. They are advertised as a quiet tyre - again, the poor quality of our road surfaces makes this tricky to judge. Porsche specialists are stuffy about tyre brands - do I care? No. They look the business and hold pressure so I'm ok.

Great tires!!! Road noise is not existing. But to be fair I have B&O sound system in my car and I might simply not hear the noise. Ride comfort is great. Driving in wet conditions seems to have no influence on them at all. It is a good buy.
