| Description of the problem | The tire pressure sensor started to leak air around the valve stem. When it was removed it was found that the cheap aluminum stem had corroded and the stem in the process of breaking off completely.. If it had broken off driving on the highway, the tire would have deflated immediately and i would be in big trouble. People automatically think that aluminum is a great metal, but it has to be anodized or alloyed to get corrosion resistance. We already had the jeep hood replaced because of corrosion. There are "marine grade" alloys available, but whether they can be crafted into valve stems,i dunno. I see by the internet, a great industry evolved in providing replacement sensors. What may have been a great idea to develop these devices, i don't see a great idea to having to replace them, what, every 2 or 3 years, at 3 or 4 hundred a pop to preclude blowing out the tire. If they are only good for a couple years, what good are they. I am going to put the old rubber stems in mine !!!! If the gov't ls putting out these silly ass regulations for sensors they should have stipulated them to last at least 10 years, or have required that they be replaced by the mfr on specific schedule. |
