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...
If you cannot find the leak, air the tire up to 20-30 pounds more than the max inflation cold. This will not hurt the tire as it is only a temp increase in pressure. You should be able to find the leak with some soapy water as you slowly rotate the tire.
i just used this procedure on my wife's suv. It was shown to me by a tire mechanic that repairs big truck tires. I was unable to find a leak in one of my truck tires and this worked.
