A tire marked A/T is designed for all-terrain use and also performs well on the highway. An all-terrain tread has many independent blocks separated by large grooves for limited off-road traction. Varied sizes and shapes of tread blocks minimize highway noise. The A/T could be compared to a tennis shoe: comfortable and dependable but only able to handle mildly rugged conditions.
An A/T tire might offer options that an off-road enthusiast would enjoy, but it is not as aggressive as the max-traction tire, designated with an M/T. These dutiful M/T soldiers easily handle muddy and rocky surfaces frequented by the serious adventurer. The M/T tire is the "hiking boot" of tires. Rugged tread elements with large tread voids offer excellent traction to handle the most severe driving conditions.
An A/S denotes all-season tires, which are dependable for many road conditions. For severe snow conditions, tires with a mountain snowflake pictograph and an M+S represent the industry's standard for tires. Much like snow boots, they are designed for wintry conditions.
When selecting tires, don't be intimidated by the choices. Think of it as a chance to shop for shoes - but for your automobile. Search for comfort, style and performance to suit your personal driving habits.
