I saw on a previous post a recall for some tires. I have the Michelin LTX A/T2 LT 275/70 R 18 tires on my vehicle.In the past month my warning light has come on twice ,reminding me of low pressure.Yes...
Remove the wheel and put it in tub of water to see if you can find air bubbles leaking out. In addition to the valve stem, it could also be a small puncture in the tire, leak at the tire bead or a crack in the rim.
