All you need to do to turn the interior sensors off is turn off your engine and take out your keys. Open the drivers door and press power lock button on your door to lock and then unlock the doors. Do this 5 times and the security light on the dash will flash quickly. Now when you get out and close the door and arm the car, the sensors will have been disabled.

You're all lucky. I get about 19mpg in my IS300

Lexus told me that the Bridgestones tread new where 8mm.

That's a great idea. I need to update mine too but £300 is a lot of dosh for a new one
