Nokian Tyres’ boss: How could we “have been so stupid”? – Ari Lehtoranta talks tyre test manipulation

,

“I didn’t have any choice.” – Ari Lehtoranta, president and CEO of Nokian Tyres, is convinced his decision to go public about the Finnish manufacturer’s manipulation of tyre tests in Europe over decades was the right decision. Lehtoranta, who has led the company since October 2014, wonders why Nokian Tyres went to the effort of supplying specially-made test tyres – particularly as the company’s non-manipulated products have always gained good results in tyre tests.

In an interview with Tyres & Accessories, Lehtoranta explains why it is now important to take part in the current public discussions on the subject and, through these talks, develop new industry-wide transparency rules.

Michelin releases statement on tyre testing and transparency

,

In the wake of the publication of such allegations, Michelin has issued a statement regarding its own approach to tyre testing. The tyre maker affirms that it has “never designed or manufactured tyres specifically for tests conducted by the media, automobile associations or any other organisations.”

Davanti completes Idiada benchmarking tests: video

,

Having launched at Autopromotec in May 2015, the Oak Group’s Davanti Tyres private brand has grown quickly, with the appointments of Sean Maddocks to UK and Ireland sales director, and Andrew Billingham and Andy Kent as regional sales managers. In addition to growing the management team, the brand has undergone a series of benchmarking tests for its current passenger car tyres at the large Applus+ Idiada proving ground near Barcelona, which has grown in stature since 1994 to become what is widely thought of as Europe’s premier independent facility – an opinion backed by the comparatively large number of tyre manufacturers currently testing on site.

The Fake Britain episode also showed the poor handling characteristics of non-compliant used tyres demonstrated on a test track and tyre assessments by TyreSafe’s tyre expert. It also gave a glimpse behind-the-scenes of a Trading Standards operation.

Goodyear the ‘top dog’ in all-season tyre test

Some industry observers assumed that the CrossClimate, the Michelin summer tyre certified for winter use, would blow away the competition in this year’s spate of all-season tyre tests. However results from the Auto Bild test published last week (issue 39/2015) show this not to be the case – a new tyre from former all-season segment top dog Goodyear dominated the results.

VW, emissions and the implications for tyre testing

,

In mid-September the emissions hit the fan for VW. What began with an admission that half a million Golfs and Beetles were not showing the right emissions values in lab tests, quickly became a global scandal involving 11 million vehicles, disastrously affecting the group’s share price, resulting in the ‘restructuring’ of the firm’s global leadership and worst of all affecting confidence in both VW and the wider automotive and automotive testing industries.

Evo tyre test – another win for Continental

Recent ads from Continental cockily ask ‘Who says you can’t win them all?’ The tyre maker raises a fair point – it has enjoyed a good run of test victories in recent times, with its ContiPremiumContact 5 topping the ADAC and Auto Bild tyre tests in Germany and the ContiSportContact 5 claiming victory in this year’s auto motor und sport summer tyre test. Here in the UK, the ContiSportContact 5 was named top tyre in the recent Auto Express test of 11 size 225/45R17 tyres, and now evo magazine has named the ContiSportContact 5 winner of its summer tyre test – for the second year in a row.

Budget SUV tyres had ‘no chance’ in premium comparison – Continental

German tyre maker Continental has shared its view on the comparative test of ten budget SUV tyres conducted by Auto Bild Allrad magazine. The tyre maker sees the test – which used its ContiCrossContact UHP as a reference tyre – as confirmation of its product’s clear superiority. In a press release, Continental comments: “None of the tested models matched the Continental tyre, which was utilised as reference tyre, in safety-relevant performance. Once again, the Far Eastern products possessed significant weaknesses.”
