New Tech reports succesful test of non-pneumatic car tyre

ERJ staff report (DS)

Boca Raton, Florida--New Tech Tire, a division of Scitech Industries said it has successfully tested a version of its New Tech Tire Airless Tyre at speeds and loads consistent with passenger car applications. The test was carried out at an industry laboratory in Ohio.

The inventors, led by Morris Corn, are seeking tyre and composite industry strategic partners to commercialise and market the product.

New tech said the tyre achieved a cool and uniform 10-hour run at highway speed at passenger car load. The tyre was mounted on a standard rim with a conventional tyre mounting machine.

The tyre is self-supporting, with internal glass fiber composite ribs supporting the load. The tyre was built & cured in a conventional steam-bladder mold at a commercial tyre factory. The composite rib and tyre construction are covered by world wide patents.

The patent, US 7546862 B2 was issued on 16 Jun 2009, shows a tyre which is in cross-section similar to conventional radial tyres, but with a much thicker shoulder, as well as a support ring inside the rim and a rubbbing strip on the inner surface of the tyre, to minimise friction when the tyre collapses.

"Commercial versions of the New Tech Tire will create a new tyre for almost any thing on wheels, from a garden tractor to the largest off the road vehicle,” stated Morris Corn, President.

The company claimed rolling resistance of the tyre is better than a conventional tyre, as well as weight-saving, due to the lack of need for spare, or tools needed for wheel replacment.

In addition, the tyre is simpler to build, requiring only three different compounds, in comparison with 10 or more in a conventional passenger car tyre. The tyre is moulded, but does not need calendering processes.

A further key benefit, said the comany is that the tyre can be retreaded many times without losing structural performance.
