With the increasing costs of gasoline, more and more drivers are looking for ways to improve their fuel economy. Fortunately, tire manufacturers have recognized this need and how tires affect fuel efficiency.
Tire rolling resistance has an impact on vehicle fuel consumption estimated to range from about 4% during urban driving to 7% during highway driving. The engine and driveline is estimated to consume approximately 80% of the fuel, while the remainder is used to overcome inertia, wind resistance, converted into heat by the brakes or consumed when the vehicle is idling. The automotive industry estimates a 10% reduction in tire rolling resistance will result in a one to two percent improvement in vehicle fuel economy. And while that may not seem like a lot, it can reduce fuel consumption by a couple of tanks a year and make the purchase of lower rolling resistance tires a better value over their lifetime. When considering a low rolling resistance tire for your vehicle, take a look at the following options:
 Michelin HydroEdge with Green X |
 Bridgestone Ecopia EP422 |
 Goodyear Assurance Fuel Max |
Thanks
Hope this helps.
Based on our testing the Bridgestone Ecopia EP422 has the best fuel economy of any tire in your size.
For the Tucson I would suggest either the Bridgestone Dueler HL422 Ecopia or the Continental Cross Contact LX20.
Hope this helps.
For the Yaris, I would go with the Michelin Defender. Hope this helps.
I have worndown EP100 ecopia
1997 Camry LE in 195x70x14?
For your Jeep I would suggest the Bridgestone Dueler HL422 Ecopia or the Continental Cross Contact LX20. They seem to do the best for SUVs.
