According to AA Insurance, winter tyres effectively improve traction, braking and cornering on wet or icy roads at temperatures below seven degrees Celsius.
However, last winter there was confusion for many customers as some motor insurers considered the fitting of winter tyres to be a modification, warranting an increased premium or, at worst, withdrawal of cover.
Simon Douglas, director of AA Insurance, says: I believe that this was a misunderstanding by some insurers.
It is ludicrous for an insurer to penalise a driver for fitting winter tyres, given that doing so both underlines a responsible approach to safety by the driver as well as reducing the likelihood of a collision.
Mr Douglas says that provided the winter tyres and wheels to which they are fitted meet the car manufacturers specification and are fitted professionally, there should be no need to inform your insurer.
But if you do tell your insurer, there should be no change to your insurance premium, he says.
If your car insurance is due for renewal it would be worth checking with your insurer first. If they arent happy about you fitting winter tyres, you could move to an insurer that is.
