Michelin claims

"Michelin says it will withstand much greater impacts than a regular tire and wheel, and will have a "dramatically" longer lifespan, while adding no extra rolling resistance, not feeling any different to the driver and adding only around seven percent to the weight of the wheel less than existing run-flat tires do."

I can't see why an airless tire would last longer. Tires normal wear out due to tread wear. Given the same tread depth and rubber compound I can't see why an airless tire would wear slower than a conventional tire. Maybe they are counting longer life due to tires not failing early due to punctures?
