No More Flat Tires July 15, 2015

Ummmm Donuts!

Currently tires are…

at their core they’re just piles of air, surrounded by a rubber donut.

Hankook Tire thinks we can do better. The South Korean manufacturer has been developing a non-pneumatic tire for a while. We first saw the concept in 2013, when it was one integrated unit, combining tire and rim in one.

Now, Hankook has completed initial testing on its fifth-generation airless tire, dubbed the iFlex. The tires do not require any air pressure, instead relying on a new type of eco-friendly material (the company demurs when asked for details). Geometric shapes built into the material provide the bounce and springiness normally provided by air pressure. But, unlike the previous iFlex, this version’s designed to mount onto a traditional rim, making it compatible with current vehicles.

Hankook ran the iFlex through a battery of tests to compare it to more conventional rubber, measuring durability, hardness, stability, slalom and speed, at up to 80 mph. The company says the tires matched conventional tires in terms of performance.

If they had these years ago, Dave and I wouldn’t have gotten to know Kevlar Chick.
(We changed her tire at the first IB gathering in Ohio)

I’d be happy with those for my lawn tractor

But how do you air down for sand, snow, and rock-crawling?

They will probably have some squishy ones for off-roading.
Kind of like my biceps.

For strictly road-going vehicles this would probably be a great innovation. But they’ve now increased the number of tires a Jeep needs to haul around by 300%.

most vehicles, even SUVs, never hit the dirt road, leave alone really rough terrain. So, it is possible for these tires to become mainstream and pneumatic tires to become an off-road speciality.

Also, there are certain elastomers whose elasticity can be varied by electric current, so in theory it is possible to incorporate those in these tires and control the amount of flex.
