Yokohama Tire Corp. says its Fuel Savings Calculator has been helping commercial fleet owners and truckers improve their bottom line through fuel savings. Now the interactive Web-based tool has the Yokohama Fuel Savings Calculator housed within the commercial Web section at http://yokohamatire.com/fuel_calculator/. The savings are shown in three ways: annual fuel savings per truck, annual fuel savings for fleet and annual gallons of fuel saved. The Fuel Savings Calculator not only saves truckers money, but also has a "green" benefit because it shows the total carbon footprint reduction of Yokohama tires, the company notes.
