the DN has previously written about the drivers that are critical to the vehicles used for school transport and passenger transport within the city of Stockholm may not be equipped with studded tires. This is according to the contract procured by the municipality and the entrepreneurs. Several readers have heard of and asked what type of tire is best when icy roads prevail.

on Däckspecialisternas Riksförbund, DRF), believes that the road conditions, and the specific situation determines which deck is best and considers that the argument that the run can always be controlled by the speed did not hold. In addition, he thinks that it is evidence that the vehicle may have studded tyres when they are both used in the city and in the countryside, and at times that are unfavorable.

– In certain weather situations and on some road sections needed studded tires, especially if it is isgata. In addition, you must have the speed to come forward. Of course, a reduced speed to compensate if you run dubbfritt, but when do you know that it is slippery? Get out there in time? It’s not safe and then it can happen, ” says Peter Buhre and adds:

in addition, request that a chauffeur should have the chain with it is the ban on Hornsgatan, I think, is a bit strong.

to the drivers themselves to decide which tyres are best and to dubbdäcksförbudet on Hornsgatan, Flemminggatan and on the part of Kungsgatan where the prohibition will be removed.

– To run without studded tires when necessary is like saying that you can run with the pads of inferior quality. I run for myself dubbfritt and there are benefits with both options. But it is up to the skier or the driver to choose the deck based on the situation. We are critical of the ban that exists on these streets.

But how dangerous are the particles, after their size, known as PM10, which arises in connection with the dubbdäckskörning? According to Bertil Forsberg, professor of environmental medicine at Umeå university, causing vägdamm according to Swedish estimates, more than 200 deaths per year.

a professor at the department of environmental science and analytical chemistry at Stockholm university, and luftexpert of the environmental administration of Stockholm city. He works thus on the management together with serviceförvaltningen has constructed the agreement that apply to school buses and passengers. He argues that it is necessary to reduce the dubbdäckanvändningen. At the same time, he points out that it is not so often that Stockholm has icy roadways, but that it becomes a problem when it occurs.

” I think there can be exceptions for these cars. Drivers can not refrain from running, without the need to transport the kids to school. You should have as few exceptions as possible, but it can certainly be justified, ” he says.

Daniel Helldén (MP) is trafikborgarråd in Stockholm. He believes that the city has a duty to keep down partikelhalten and to dubbdäcksförbudet is necessary.

” We have a duty to keep order on the Stockholmsluften. In the past, the state would have received a fine of sek 100 million of the EU on the basis of the air here. It meant that we introduced a dubbdäcksförbud. PM10-particulate matter is directly harmful to people’s health, ” he says.

According to Daniel Helldén is stud-free tires are usually good enough to ride in the Stockholm region shall be safe.

– There are times when they are not there, but there are so few times that the health aspect weighs heavier in this case. The dmv is clear that there are stud-free tires that are so good that it should work. You will have to adapt to the road conditions prevailing. The largest taxi company in Stockholm is Taxi Stockholm, has not some studded tires and have done well.

the Swedish transport administration is clear that there are stud-free tires that are so good that it should work.

– It is difficult to answer because I do not know what cars they have, and that Taxi Stockholm does not have. But we don’t have any studded tires, which means that we get up partikelvärdena.

the Swedish transport administration makes it quite clear that studded tires are not needed, but there are special vehicles which is not capable of running without it, I think that they can comment on it instead, ” says Daniel Helldén.
