I just had the valve stems replaced (due to cracking) on my Jeep. They were coded as tr413 (obviously the same dill number covered in the recall. However, these tires and valve stems were installed on my car in December of 2005 - clearly not manufactured during the August-December 2006 time frame of the recall. This raises the question about the dill/chinese valve stem problem being much larger than has been claimed. I am a retired former rubber chemist, and have run hundreds of ozone resistance tests on rubber compounds, so I am fairly familiar with what to look for. Nhtsa should expand its investigation of this problem. I kept the old valve stems which were removed, and will make them available upon request.
