Non-pneumatic tires are currently in the testing stage for cars, light vehicles, and some light military vehicles. This type of tire negates the need to fill the tire up with air due to it’s flexible design. Michelin (owner of BFGoodrich, Kleber, Riken, Kormoran, and Uniroyal), Bridgestone, and Resilient Technologies with the University of Wisconsin all have working prototypes of these polymer tires. This type of tire design actually has load bearing, shock absorbing, and handling characteristics that are similar to or better than conventional pneumatic tires. Since they do not have to be maintained at a proper air pressure, they are always in the optimal zone for fuel efficiency. Holes can be integrated into the road surface part of tire itself since air is not held inside and this means that hydroplaning does not happen because the water will just go through the bottom of the tire. Only the outer tread needs to be replaced and this means that the environmental impact is lessened and possibly the cost of replacing worn tires is reduced as well.
