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.
Measure the coffee for your latte. Each espresso shot will need to have a specific amount of coffee. Most lattes are made using a double shot of espresso, which means two shots. For each shot of espresso measure out 18-21 grams of ground coffee. You can do this by putting the espresso machine's portafilter on a kitchen scale.
