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

UTQG ratings on sidewall of Toyo Tires Proxes R39 tire UTQG ratings (top) and tire code (bottom) on sidewall of Continental ContiProContact tire. Uniform Tire Quality Grading, commonly abbreviated as UTQG, is a set of standards for passenger car tires that measures a tire's treadwear, temperature resistance and traction.
Developments in tyres, particularly the development of radial-ply tyres, also permitted a multi-purpose tyre that performed well both on and off-road. The usual military replacement for a bar grip tyre today is now a pattern like the Michelin XCL or 'NATO Pattern'. This consists of large solid rubber blocks, of similar size to the bar grip bars.
Force variation axes. Tire forces are divided into three axes: radial, lateral, and tangential (or fore-aft). The radial axis runs from the tire center toward the tread, and is the vertical axis running from the roadway through the tire center toward the vehicle.
