Valve stem failure. Rapid deflation of tire. 2nd failure on this vehicle. 1st failure was 09/23/2008 on a different tire - vehicle not moving at the time. Driving along at highway speed 50-60 mph, 30 degrees, 8:00 am est. Low pressure warning indicator come on. Within a few minutes I feel truck handling change. I pull over into parking lot. I touch valve stem and here air escape. Within 2 more minutes tire was completely deflated.
2 oem valve stems have failed due to material defect. Both failed stems cracked at the on the stem enters the tire rim. These failures occurred on my 2007 Ford Explorer Sport Trac. All equipment is as delivered new from the factory.
I have had to get three valve stems on my 2007 Ford Explorer Sport Trac replaced within 3 days. They were cracked and rotted. 2007???? cracked and rotted??. At first I thought someone was cutting my valve stems on purpose. When the tire guy pulled to remove the old valve stem they split in half with hardly any force exerted on them. Now I find out that Ford knows about this problem. . Unreal.
