Though the tire won't go flat from puncture, eventually the tread will wear, but Johnson points out that in the past, that has been a rar- ity in the ORV market. "The good news is most ORV tires, they don't ever wear the treads out because we have punctures and stuff well before we ever have to worry about tread wear," he said. "So it is going to wear like any other tire; there is a wear element. But the good news is we get to worry about that instead of punctures at 50 miles." While the tire is only currently available for the military MV850 and WV850 and a limited number of consumer Sportsman WV850 H.O. ATVs released in December, more consumer applications are in the works. "It will be offered as a standard option on a variety of ATVs and side-by-sides later this year," Dutch said. "We're going to offer the non- pneumatics on our side-by-sides, and that's geared more toward the work environment at this point because we've had so much feedback on this coming from that community." While Polaris is looking forward to rolling out the tire on more of its lineup in the near future, the OEM and Resilient have found that each vehicle requires that the NPT be tuned differently, so different versions must be cre- ated, depending on the vehicles' size and use. "What we mean by tuning, it's basically we're balancing the geometry of the web with the material of the web and the physical prop- erties of the tread band, the lug pattern, the material stiffness, so the tires perform in con- cert with the operation of the vehicle. We have to take things into consideration such as the weight of the vehicle, its capabilities, as well as the ease and the smoothness of the ride," Dutch explained, adding that different itera- tions may have different tread patterns or dif- ferent web material thickness. CREATING A SMOOTH RIDE Polaris has also had to factor in each vehicle's composition before adding the tire to it. Switch- ing a side-by-side or ATV from an air-filled pneumatic tire to an NPT isn't as simple a pull- ing out a few lugs and installing the NPT. "I can speak to this from experience. We thought, 'Hey, let's just bolt those things on; they'll fit,'" Johnson said. "There's a mas- sive amount of interaction between suspen- sion components, frame, driveline, steering and the tire itself, which we've learned as we've dug into this. That's why it's only been launched on two of our vehicles so far. You might physically be able to bolt it on and bolt it off, but if it's not properly tuned and you don't have the right integration from vehicle down through the tire, you're not going to have the best experience." But, Dutch explains, altering the makeup of the vehicles wasn't completely unexpected, considering that has happened when tires have changed in the past. "I think a lot of people forget that when we went from a bias-based tire to steel belts and radials, there was a transition with the automakers. They had to do different things and upgrade their suspension for that vehicle to be able to work with that new technol- ogy. And we're kind of going through that same process with it, so as we work through it, there will be more applications," he said. "We want to make sure that we're careful in putting it on the next application or the next platform. We want to make sure that it's a good fit for both the driver and the machine." It's likely that if dealers start carrying the NPTs on their shelves, they'll be selling them with an entire suspension upgrade package, except when NPTs are being replaced on vehi- cles on which they came stock. The NPTs are designed for most military and consumer uses as they can be tuned for everything from rock crawling to riding the dunes, and with the webbing pattern, they're self-cleaning, as the honeycomb shape spins dirt out as it's rolling. The only terrain the NPT isn't currently designed for is thick mud or deep, soft sand, but those are both areas that Polaris is studying. "ATVs are normally equipped with a tire that's most capable of handling a broad range of environments, so just like we're devel- oping different size NPTs for future vehicle platforms, we're also looking into developing multiple treads, and these could be precisely See Polaris tires, Page 17 See Polaris tires, Page 20 POLARIS TIRES CONTINUED FROM PAGE 16 Polaris reports that its non-pneumatic tires will be available on a variety of consumer ATVs and side-by-sides beginning later this year. Polaris' non-pneumatic tires were originally designed for military use. In tests, they've kept moving, even after being shot with 50-caliber bullets. P14x20-PSB7-Focus.indd 17 5/14/14 2:11 PM
