The new Polaris Sportsman WV850 H.O. ATV/quad shows off its Novel Airless Tires, which isn't very new, but they're really durable; the kind that have only been used for military applications.
It won't be a true mass-production effort, because the WV850 in this spec will only be sold in limited numbers, starting from $14,999 (€11,100).
