Looks like everything is fine, but I do make it a habit to manually check my tires every month (always in the morning, after the car has sat overnight, so as to get a good cold tire pressure). When the car was a month old, I checked and all tires were low. I added air to all 4 and decided they must not have seated the new tires well--or something. But, in the past month, I have checked the tires each Sunday morning--and the cold tire pressure (using the same air gauge)has decreased each week, & in every tire. After the last check, I aired all 4 up again! The loss was 2.5 lbs in 3 tires and 3 lbs in tire four. The spare's pressure has remained constant. I am in Dallas, TX, and it is hot here this time of the year. That being said, usually at the first cold snap each year I would loose tire pressure in my prior Lexus models with the tire monitors--I knew, because of the monitor. After 3 months of continued air loss, I took my car to my dealer--they remounted all 4 tires and aired them up to 36 psi. I just checked the tires and all 4 are loosing air as before (approx 1/2 lb per week). I plan to give this a couple more weeks to make sure the air loss continues--But who should I contact "Bridgestone or my Lexus dealer"?

In regards to chromes and losing air. On my LS430, I started losing air on the oem factory chrome in one tire. I brought it to Discount Tire (where I bought additional lifetime rotation and road hazzard *prorated*) and they said it was due to the wheel not the tire. I brought it to my Lexus dealership and they asked if I had hit any bumps and told them I had not. They ended up replacing the wheel under warranty.

I now have a 2007 week old Smokey Gray LS460 (ML, ADV Park, etc etc) with 18" chromes and hope this is not an inherent problem with chrome wheels. Unfortunately after reading the threads, this appears to be the case.

PS will a mod allow me to change my screen name? I want to change it to something more generic rather than the last car I had.....
