Our long country offers often highly variable and sometimes very challenging driving conditions, especially during winter.
Nevertheless, we have a law that is so strict that in practice it can make the best studded tires on the market are not legal here on the rock.
In any case this winter. But to fall there will be changes on this.
Therefore, you must put on the tires right way
Sweden and Finland is ahead
In Norway namely the rule that a studded should not have more than 50 spikes per roll meter circumference. The same rule applies in Sweden and Finland. However, they have adopted an exception that allows the number of spikes kanoverskrides – while it can be demonstrated that it does not increase asphalt wear.
Norwegian authorities have also given an exemption from the prohibition of tires that are permitted Sweden and Finland until 1 October 2017.
Market leader Continental coming this fall with a brand new tires that are covered by this. It is in principle prohibited in Norway, but saved thus initially by the exemption.
– The new spike tire has several spikes and provides better grip on ice than its predecessor. The amendment in Sweden and Finland are good for road safety and road attrition, and we believe that the Norwegian exemption will go into a permanent amendment in 2017, says Technical Manager at Continental, Frank Larsen.
Calling new tire labeling a disaster
50 percent more spikes
Continental IceContact2 have, depending on the size of the tire, up to 50 percent more spikes than predecessor, which improves isgrepet without asphalt wear increases. The spikes are however both smaller and lighter than earlier so that wear on the road surface is not larger.
This is tested by running over a granite slab 400 times for 100 km / h. On the way, one can see that the wear on the road surface is not greater even if one has several spikes in the deck.
– This is good news for consumers. With IceContact2 they have from autumn 2015 the opportunity to buy a tire that is better, especially on ice than previously, while not struggling more on the road, says Larsen.
Therefore, be extra careful with new studded
25 percent lighter
The new studs on this deck is both smaller and 25 percent lighter than the spikes on predecessor, and this also means that the noise level is lower. The spike is specially designed to provide the most grip on ice, as well as specially designed reservoir front and rear spike to give room to crushed ice, which would otherwise hindered full spike effect.
Tyre characteristics by driving on dry asphalt improved by nine percent, while the improvement is two percent on ice. However, it is when it comes to braking and acceleration but sees the biggest difference.
To prevent spikes fall out when driving, Continental has developed a special technology that anchors spikes better covered. The spikes coated with “binder” and assembled by robots in the specially developed spike holes.
“binder” is activated then in a special climate chamber and ensures that the spikes are sitting in the deck.
This ensures 400 percent firmer attachment of spikes than is possible with conventional processes. Each spike can withstand tensile forces of up to 50 kg without being pulled out of the deck.
Winter: This year’s test winners
