The Michelin Agilis CrossClimate is Michelin's most durable heavy duty truck tire. Michelin's CurbGard? technology resists curb scrubbing and has twice as much nylon reinforcement the Michelin Defender LTX M/S. Under heavy loads, the Agilis CrossClimate lasted 10-19% longer then three competitive commercial tires. SipeLock? technology provides hundreds of biting edges for improved wet and snow traction.
