Tire blowout, stupid valve stems.. Options

[Andyrew]

So im driving my car back from sears, after getting the right tires fliped (they installed the tires as 4 left.. the tires I got where directional..) Im not 10 miles away, and I hear this pop, and PPPHHhhhhhhhssss, Sounds very much like a blow off valve right next to me.. Thats fine, some guy in a turbo just passed me.. one problem, no one passed me.. Then I feel this slight tug and hardening of the steering wheel.. Instantly I slow down and pull off the road safely. Yuppers, left front tires valve stem is gone. now I just got these tires... Im saying this is my first drive over 2 miles.... 225-50-16 kumo 711's.. and I got a little pissed... Call dad, he comes with one of my cookie cutters.. switch tires and baby it home. Valve stem is not in the tire.. and it looks like it shot out. They just replaced the valvestem, and Im going to put in some bolt in valve stems. Im wondering why that stem popped out.. Dad says its because the wheel is polished.. but that doesnt make sense to me.

Im going to put the bolt in stems on all of them, sears didnt ask me if I wanted new stems, but they put them in no charge.. nice of them.. but not good.

I've had two valve stem failures in the past 12 months. First one was a slow leak that required adding air about once a week. The second one leaked on my way home from work and required a roadside tire replacement.

I use the best tire shop in town and they could not come up with a good answer as to why this happened.

I'm running polished Fuchs.........6x16 in front and 7x16 in rear. Both of my leaks have occured with each front tire. I doubt that that polishing has anything to do with this as the tire stem hole has not been sharpened while going through polishing process. My ride is not used on the track and my street driving is more high speed than high G.

All is OK the last 5 months or so. The next time it happens, I'll upgrade to something stronger.

Where are you guys buying heavy duty (racing type) valve stems? My tire guys did not have a source and were a little nervous about specifying what would work with the Fuchs.
