Wal-Mart uses super single, low rolling resistance tires on its company trucks. Although they are more expensive, super single tires are as safe, or safer, than two-tire designs, and are much easier to remove and replace. Rolling resistance tires decrease the amount of effort required for the tire to roll.
Wal-Mart considers many features when it chooses the type of tires to use for its trucks. The company takes into consideration factors such as the miles per gallon associated with various types of tires. Wal-Mart also takes into account the type of climate and the terrain through which the trucks are travelling.
