Multiple technologies have been applied, including an innovative AeroWing™ sidewall lug design, advanced tread compound, and optimized tread pattern to address the unique vehicle requirements, such as instant torque, rapid acceleration, the additional weight, and range efficiency. It also carries the Three-Peak Mountain Snowflake symbol for year-round, all-weather dependability.
