I've got an '05 Explorer with about 13k miles. The tire pressure sensor warning is about to drive me crazy. The dealer has replaced all 4 sensors under warranty, with no relief. We've compared tire gauges, with mine about
3psi below his. He's telling me I'm not keeping them inflated, the weather is cooling, etc. While the second argument is true, I don't buy it as the cause. A couple questions -1) Does anyone know at what psi these sensors are supposed to activate? I had been running 35 psi on my gauge, and have increased to 38 psi. I'm not comfortable taking it any higher.
2) These warnings NEVER go off immediately when I start driving. It may be 15 minutes later, maybe 2 hours later. It seems to me if the tire pressure was actually too low, I would receive the warning immediately. Is that a bad assumption on my part?Any and all feedback is very much appreciated. Thanx, JW
