Fuel economy can be a major factor for some tire consumers. If you're considering buying a tire that can assist in your vehicle's fuel economy, know that not all tires are made alike. Purchasing a tire that is different than the one you had when the vehicle was new may impact the fuel economy, for good or bad.
According to Bill VandeWater at Bridgestone Firestone North America, "consumers can see a 15 to 20 percent difference in their fuel economy depending on the tire they select." Some studies have shown that many consumers like high fuel economy, but not at the cost of mileage or performance, especially in wet conditions.
