There is less of a pressure change when the tires heat up verse when they are cold, compared to regular air. The Selling point at dealerships is that the low/flat tire light won't come on as much. "It is not worth it on any street vehicle", it is only useful in race cars, were tire temperature get close to 200 degrees. In a race little pressure change can cost alot of track time and affect handling.
