Designed with cutting-edge, semi-pneumatic technology, McLaren Nu-Air tires cannot be classified as pneumatic, foam-filled or solid tires. They are engineered to deliver the durability of solid tires with the soft, cushioned ride of pneumatic tires — all in one product. Manufactured from heavy-duty rubber compounds, Nu-Air tires are designed to withstand the harshest operating conditions and the most massive loads. These all-terrain tires provide maximum performance both on- and off-road, even in severe cutting conditions. The specially engineered tire structure prevents cuts and snags, ensuring that users will never waste time and money due to tire punctures again. The deep lug tread pattern is designed to provide traction in snow, sand or deep mud. Nu-Air tires have three times the life expectancy of pneumatic tires.
