Now for a small test. Who wrote this:
Tires that are underinflated by 6 to 7 pounds per square inch increase tire rolling resistance 10 percent or more, increase tread wear rates and tire fatigue. When a tire is underinflated, the tire’s road contact zone and cyclic stress level changes resulting in undesirable loss in tire and vehicle performance.
To prevent the above, we recommend the following in maintaining proper inflation level (a vehicle’s proper inflation level can be found either on the door or on a placard in the glove box) and in checking tire wear:
â€¢ Check tire inflation pressure (including the spare) at least once a month and before every long trip. Tires must be checked when they are cold; that is, before they been run a mile.
â€¢ Tires should be rotated at least every 6,000-8,000 miles and the alignment should be checked once a year. Misaligned tires can cause the car to drag, which lowers mileage and causes unnecessary tire wear. If your tires need replacing, check out these discounts on Goodyear Tires to save yourself some money.
â€¢ At least once a month, motorists should inspect the tires closely for signs of uneven wear. Uneven wear patterns may be caused by improper inflation pressures, misalignment, improper balance or suspension neglect. If not corrected, further tire damage will occur.
Nearly ninety percent of drivers don’t check their tire inflation properly. However, this percentage is starting to drop as gas prices underinflate consumer pocketbooks.
With escalating fuel prices, the time is now for drivers to focus on simple things like proper tire pressure to maximize tire performance and increase fuel economy.

The answer is “4”. Check it our for yourselves.
Meanwhile McCain is mocking Obama’s suggestion that Americans can do more for immediate relief with proper tire inflation than with off shore drilling, and handing out these tire pressure gauges.
Tell John McCain to shove this thing up his ass.
