Spotting abnormal tire wear and correcting the cause can significantly extend tire life. Normally, tires will wear evenly across their surface until they reach the wear bars, which are 2/32nds of an inch above the bottom of the tread. When the tires are worn to the wear bars, they should be replaced.
One shot (1.5 ounces) of espresso has about two tablespoons of coffee (about 1/4 ounces). For best flavor, one shot of espresso, or two tablespoons of coffee, should be used to make 6 ounce of coffee drink. Likewise, a 12 ounce coffee drink will taste best with two shots of espresso.
At Starbucks, a 12-ounce cappuccino has 75 milligrams of caffeine, or one espresso shot, compared to the 260 milligrams of caffeine in a 12-ounce drip coffee. This means that anyone who is used to drinking drip coffee may want to order an extra shot or two with his cappuccino.
