HUMMER TIP OF THE DAY
Posted: Sat Feb 13, 2010 10:49 am
you may notice that one tire that slowly loses air pressure over a period of days or weeks.
Abrasive elements in the environment may intrude between the tire and wheel at the bead seat. There is always some relative motion between the tire and wheel (when the vehicle is driven) and this motion may cause the abrasive particles to wear the wheel and tire materials. As the wear continues, there may also be intrusion at the tire/wheel interface by corrosive media from the environment. Eventually a path for air develops and a 'slow' leak may ensue. This corrosion may appear on the inboard or outboard bead seating surface of the wheel. This corrosion will not be visible until the tire is dismounted from the wheel. The correction is to cleaned the corrosion from the wheel with a light sanding and then coat the area with tire bead sealer to prevent further leaks and corrosion. cheers
