My 07 edge had the same problem. Tire went flat while driving on the Interstate. The tire was ruined before I could get stopped. The valve stem failed and the other three were cracked. My dealer had seen this issue before and replaced the stems and the ruined tire. Ford has not acknowledged there is a problem yet, but I definitely believe there is one. So far my 07 F-150 is ok. I have done some research and they think that up to 6 million valve stems were produced without ozone and uv inhibitors in the rubber.

 

Man o man Tylus your amazing! Everyone, since Tylus hasn't experienced this problem then it must be in your heads and just plainly doesn't exist at all. Just because your special Tylus and have not ever had issues with your valve stems, dont mean others have not.

 

Years ago I had a stem fail on my van while I was pulling a 30' travel trailer on the freeway at 65 mph. I posted at that time about it. Since then I have all my valve stems changed to Short-Short Metal Tire Valve, Tires & Supplies - GEMPLER'S

 

and your back

 

I get all of my tires at a Disc***t tire dealer, and they wont warranty a tire unless they have put new stems in with the new tires. Would Chinese tire stems be a surprise in this day and age?

 

This is legit guys. Over the past week or two, our local (Chicago)NBC (channel 5) news station as aired 2 reports about it. I will paste the link to their website below. I believe most of them are on 06 and newer vehicles.


Defective Tire Valve Stems Could Be Dangerous | NBC Chicago

 

Here is an article on the subject; Warning issued on faulty tire valve stems following rollover death: Consumer Reports on Safety

 

I had a metal stem on a wheel come lose on Tuesday and it ruined a high performance Parada Spec-X tire. Tire was replaced under warranty but it could have been really bad had the stem leaked fast. So, check those metal stems... they can come unscrewed.

I'm now in the process of looking for a good TPMS system for my 2006...

 

I haven't received one of these letters yet, but I had a valve stem go bad on my 2007 F150 yesterday and found this while doing a search.

Ford Replacing Defective Tire Valve Stems, But Issues No Recall

 

Ford will nor replace all the valve stems for free, call your local dealer.

 

There has been an issue on some made in china valve stems. They were made for Dill who in turn sold them by the millions to all of the manufacturers and tire wholesalers, etc. I don't think Ford or any other car manufacturer has acknowledged or issued a recall, but Dill has acknowledged a problem. This has been reported in the media, but it has not been leading story news. If memory serves me correctly, 06 and 07 was the approximate time frame for manufacture of these defective stems.

 

I got a letter from Ford about a week ago regarding the valve stems on my '07 Explorer. Seems they are cracking at the base of the stem, and I can return to my dealer for replacement. Maybe the valve stems on the F-150 are the same, but no letter from Ford about them.....................yet.

 

I had this happen on the Mustang about two years ago, it was a valve stem NTB put in.I was cruising allong and PSSSSSST then the front right dropped at 70mph. I tought I ran over a piece of debri,but nope darn valve stem cracked.

 

is that 41 psi per the sidewall rating or fords rating on the doorpost.

 

I've never had a valve stem failure since my first vehicle in 2000. However this past Thursday, June 5th 2009 I experienced my first failure. The valve stem on my tire was also cracked near the base, it was not a slow leak either. I was really fortunate, because I had just driven 50 miles on the highway to my girlfriends house. I'm not sure if it was already happening when I was driving or once I had parked. What I do know is that my tire was almost completely flat once I came outside to drive back to my place. I put air in the tire and then quickly took it to the closest and available tire shop which ended up being Sears. Keep in mind that my tire was leaking the whole way, I slowly made my way to sears and got all 4 stems replaced. I couldn't throw on the spare cause I have bigger than stock size tires on my truck and the flat was in the left rear. I'm sure it could have been a lot worse, I definitely recommend you all check your tire stems just to be safe.
