Warning issued on faulty tire valve stems following rollover death
The death of a Florida man in a rollover accident coupled with the recall of faulty tire valve stems made in China has prompted at least one safety expert to caution consumers to check vehicle wheels to make sure they don't contain the rubber replacement tire valve stems. The valves may crack prematurely and lead to serious crashes, says Sean Kane, president of Safety Research and Strategies in Rehoboth, Mass.
One U.S. distributor, Tech International, recently issued a recall of 6 million of the Chinese-made valve stems, which have been tentatively linked to the fatal rollover crash of an SUV in Orlando last year. The valve stems were made for Dill Air Control Products of Oxford, N.C. by Shanghai Baolong Industries Co. in China.
On May 15, the National Highway Traffic Safety administration opened an investigation of the valve stems.
Dill has told NHTSA that as many as 30 million of the suspected valve stems have been distributed in the North American market. The suspect valve stems identified by Dill include its TR-413, TR-413 chrome, TR-414 and TR-418 models, which were manufactured between August 2006 and November 2006. (The valve stem is a rubber tube with a metal valve used to inflate the tire with air.)
