Slow down.
True
Understand that the primary function of tread on a tire is to divert water from beneath the tire to improve traction and avoid hydroplaning on wet roads.
...Vehicle is suspended in mid-air.
You will lose traction especially on wet roads.
A vehicle loses traction on wet roads especially if the tires are worn.
Cars might skid on wet roads because water creates a layer between the tires and the road, reducing friction. This reduced friction makes it easier for the tires to lose traction and slide, leading to skidding. It is important for drivers to adjust their speed and avoid sudden maneuvers to prevent skidding on wet roads.
They won't provide more traction when the roads are wet, it would be like driving on ice.
Salt or a mixture of salt and sand is typically placed on roads when it snows to melt the ice and improve traction for vehicles. Sand alone can also be used to increase traction on icy roads.
Yes, It is a rating of how well it "stop" in the wet. AA is the highest rating, A, B, C is the lowest.
Tire Ratings - Traction grades Traction grades are an indication of a tire's ability to stop on wet pavement. A higher graded tire should allow a car to stop on wet roads in a shorter distance than a tire with a lower grade. Traction is graded from highest to lowest as "AA", "A", "B", and "C".
Quite a bit especially if your tires are worn down to or below the tread depth limit.
It notifies the driver that the road conditions are creating reduced friction between the tyres and road surface, hence, reduced traction. You'll see it on particularly wet roads, snow/ice covered roads, etc.
