If your eyes are having trouble reading a tire gauge, how about one that talks to you and tells you the tire pressure? Simply push the nozzle of the gauge onto the tire's valve stem and the gauge will speak the air pressure! You can also program in the front and rear tire pressures (seems like I'm always searching for this information in my manual) so you know where to set them quickly. Place one in every glove box... because it's my guess your tires are under-inflated and the increase you'll see in fuel mileage will pay for this gauge in no time!
