USE WIDE SINGLES. Wide singles weigh less than doubles and save fuel. They also cost less than the two tires they’re designed to replace, although you have to buy new rims to get in the game. Wide singles are retreadable, too. An automatic tire inflation system can help keep the tires inflated to proper pressure.
