Dear bbf: Sorry, I missed your point about the wear bars. Yes, understanding the location of the wear bars, the wear bar that is nearest the inside of the tire (toward the engine) CANNOT be felt without sticking my finger inside the tread. So, it sounds likely that it may be an alignment problem. Again, thanks!

Dear bbf: You've been very helpful. I'm taking it in for an alignment check and rotation tomorrow and will air up before I go. This experience and your advice have made me a true believer in timely rotation. Thanks for the lesson! BTW, "beerchug" shows up on the "quote" in the reply process instead of icons. Since I'd seen the icon on the post, I just assumed that was your screen name. Have a great day!

******************************************************************** Beerchug - Thanks for this heads up! I have TWO tire guages - (HA! - I've been cruising the forums and felt pretty smug about having a backup, but I see I was taken in by the prospects of TPMS being something more than an "idiot light" - DUH!) Both read 30 PSI on the front tires - 35 is recommended. The wear is about the same on both tires, with all wear bars showing except the inner one (3 of 4). Does this sound like underinflation?

I purchased my used (6K mi) 07 MKX (FWD) in December 07 from a reputable Ford dealership. They had replaced the tires (why didn't I ask why???????????). I've put 9K miles on this car (mostly highway miles), and the front tires are worn to the wear bars. The back ones are fine (although I've had 1 hole in each of the rear tires repaired - LOVE the pressure sensors!!). I had planned to rotate at 10K. It drives like a dream to me, no vibration or shimmy whatsoever. Any ideas on what the problem might be?
