Since the largest variation of snow socks is in the market for cars and pickup trucks, wide or low-profile tires are often covered.
The snow strength developed by compaction depends on the properties of the snow, which depend on its temperature and water content—wetter, warmer snow compacts better than dry, colder snow up to a point where the snow is so wet that it lubricates the tire-road interface. New and powder snow have densities of 0.1 to 0.3 g/cm 3 (6 to 20 lb/cu ft).
Rainfall intensity, the amount of water likely to generated in a two-minute rainstorm is more important than average rainfall, the British Standards Institute [14] notes that an indicative storm in Essex, (annual rainfall 500 mm per annum) delivers 0.022 L/s/m²- while one in Cumbria (annual rainfall 1800 mm per annum) delivers 0.014 L/s/m².
