And of course if your valve stem fails, no amount of sealant will help! :flag:mdernst said:The Mobility kit was stamped good until Oct. 2006. I believe the tire damage was too severe for it to work. The tire was a Michelin Pilot Sport PS2 with about 5000 miles on it.
I believe it was a puncture (nail, screw, etc.) that came out on the interstate. I heard a pop and then heard something hit the underside of the car. It sounded like I had run over something in the road but I hadn't seen anything in front of me nor did I see any debris in my rear view mirror after the noise. Within a few seconds of the noise I changed lanes and the rear end felt "squirrelly" and within a few seconds of that I got the dreaded TIRE DEFECT on the dash. A few more seconds to clear traffic and get pulled over on the shoulder and it was all over but the crying...
All of this happened (from the initial noise to my stopping on the shoulder) in less than a minute and from the looks of the tire I believe the sidewall damage from running on it flat for that short period of time is such that it will require tire replacement. I never did see the actual puncture spot.
