A few days ago Presidential Candidate Barack Obama advised the Americans to inflate their cars’ tires. This move, said Senator Obama, will help us save money on gasoline. I’ve heard and read many discussions on this subject, and would like to bring to your attention a few (reasonably short) articles, which I found interesting and informative.

 
1. An article “ FACTBOX: Government backs Obama call to inflate tires” by Reuters discusses the subject and offers Energy and Transportation Departments’ recommendations, such as: “Proper tire inflation also plays a large role in keeping vehicles fuel efficient. For example, a vehicle with a recommended pressure of 35 psi whose tires are at 28 psi will have increased its rolling resistance by 12.5%.” and “If you keep your tires inflated properly, you can improve your fuel economy by as much as 2.5%.The recommended tire pressure can be found in your owner’s manual or on a sticker on the doorjamb of your car, not on the tire itself.”

 
2. Kate McLeod in her article “Tires are the key to gas bills savings” in San Francisco Chronicle writes about rolling resistance of your car’s tires.
Here is one quote for you to ponder upon: “Not all tires are created rolling-resistance equal. Rolling resistance is influenced by design, dimensions and tread compounds. Different tire brands of the same size and type to equip the same vehicle can differ by up to 50 percent in rolling resistance or fuel efficiency performance.”

 
Also, “Ask about high fuel-efficient tires. Make sure you’re getting well-rounded performance. Tires that improve fuel economy but last only half as long won’t be a good value in the long run”.

 
3. How to find out the correct pressure for your tires?
