Until technology intervenes you will have to remember to do it yourself.

By 2008 all new cars will be equipped with a system that monitors tire pressure and alerts the driver when they need inflating. Right now, about half of the 2006 models have the feature, and the number will go up to 70 percent in 2007. The sensor alerts drivers when the air pressure is 25% lower than recommended.

Under-inflated tires lead to accidents and cause your car to guzzle more gas. In fact, keeping tire pressure at the proper level translates into a free tank of gas annually.

In cold weather tires lose pressure. Even a 10-degree drop in temperature affects the amount of air in your tires.

Even when all cars have the monitor, the Alliance of Automobile Manufactures recommends that you check air pressure every month and before you take a driving holiday.
