With gas around $4 a gallon, sometimes I wish I owned a Prius.
Fortunately, the major tire manufacturers are starting to release fuel efficient low rolling resistance tires in SUV sizes.
Bridgestone recently released the Ecopia EP422 in the popular 235/65-17 size (current price is $116* plus shipping). 235/65-17 is a common Original Equipment size (please double check your size) on many mid-size SUV's. 235/65-17 is used on the Acura MDX, BMW X5, Chrysler Pacifica, Ford Edge, Jeep Grand Cherokee and the Volvo XC90.
Based on other Bridgestone tires we've tested, expect to see good wet grip, reasonable treadwear, improved fuel economy and good overall performance. This Grand Touring All-Season tire enhances a vehicle's fuel economy by reducing tire rolling resistance along with carbon dioxide emissions while delivering year-round, all-season traction, even in light snow.
Bridgestone says that the Ecopia EP422's 36% improvement in rolling resistance compared to a conventional Bridgestone tire may yield about a 4% improvement in fuel economy.
"[My] Jetta drives like a different car since the switch from the stock Bridgestone tires. Much quieter and more comfortable ride and feels more stable over rough surfaces. Highway fuel economy has increased from a range of 42-44 mpg to a range of 44-47 mpg..." -- Tire Rack Consumer, 2006 VW Jetta TDI
"A solid 4 mpg improvement over my previous tires..." -- Tire Rack Consumer, 2008 Toyota Prius
