CAR your deluded, gritters only really work well on dry roads and only when theyer expecting light snow or frost.
On wet roads it just gets washed away and gritters will never lay enough salt down to protect from heavy snow, youd need a gritter going up and down a road all night to protect from it and then you have the problem that as the salt melts the snow the roads get wet and wash the salt away.
As piggy rightly points out winter tryes are for the whole of winter. They are better at clearing water when it rains, a more suitable compound for 10*C and below as well as being better on snow and ice.
Theres at least 3 months of the year when they are good to use on the road, probably stretching to 4, 5 or 6 some years.
