A new generation of LRR tires coming soon (plus: video of coastdown comparison)
Found this interesting promotional video of a coastdown test of three tires at the Nokian factory.
Nokian Tyres - Summer tyres - Winter tyres - Friction tyres - Studded tyres
This is the promo article in Tire Review
Quote:
Nokian Tyres’ new prototype “tire of the future” rolled 64% farther than an eco-oriented summer tire in a recent rolling resistance test conducted at the tiremaker’s logistics center in Nokia, Finland.
In the test, conducted with Finnish motor journalists present, a car fitted with three different set of tires – The prototype tire, an eco-oriented summer tire, and the Nokian Hakkapeliitta R friction tire – rolled in neutral off a ramp in windless conditions. The eco-oriented tire rolled 78.9 meters, the Hakkapeliitta R 99.5 meters and the “tire of the future” 129 meters, according to Nokian.
“Our tire of the future nearly reaches the best EU fuel efficiency class A and consumes considerably less than the best passenger car tires of today, which are two classes worse and only get class C,” said Teppo Huovila, vice president of R&D with Nokian Tyres. “Nevertheless, the prototype offers a normal level with all other features.”
