Ramat Hasharon, Israel - Pelmar, an engineering company based in Israel has announced a new concept in runflat tyres. The idea takes a conventional tyre and inserts a rib along the central plane, to make a two-chambered product. If one chamber is punctured, the other can provide enough support to keep the vehicle mobile, said the company.
Pelmar currently has 2 patents pending. The concept was developed by the inventor, Eldad Rubin, with the investment mainly by Pelmar. The concept was investigated initially on behalf of Pelmar by Smithers Scientific Services Inc. in Akron and further developed, refined and tested in cooperation with ARDL, (Akron Rubber Development Laboratory).
Pelmar says the Lynx run flat tyre provides a solution to loss of structural integrity and loss of vehicular control that result from punctured tyres, "without requiring a significant change to the manufacturing and service infrastructures". As opposed to other manufacturing methods, Pelmar's Lynx process does not require the use of polymers or material that differ from those currently used today, said the company.
Pelmar added that the new system also does not require significantly different wheel rims or different casting or forging processes.
ERJ reported on a multi-chamber runflat tyre shown aon Bridgestone's stand at the 2006 Geneva motor show. Pelmar says it is studying whether that product breaches Pelmar's patents.
Pelmar is best known as a company that refurbishes and sells used machinery in the tyre and rubber industries.
Pelmar said it will reveal more about the Lynx concept at this week's ITEC show in Akron, where it has a stand (Booth 925).
