Just installed Bridgestone Ecopia EP100 185/65/15's on my 2004 Prius. Original Intergrys lasted 23K Second set were Michilen Destiny's (Discount Tire Only). They were great at first, but after 30,000 miles became very noisy. Finally replaced after 57,000 miles. The Ecopias were not stocked by my local Discount Tire. The manager said he had never installed them on a car and swayed me toward some Pirelli . Bleh. Driving away they are much quieter than the Destinys. I didn't drive the car while the Integritys were installed (just took the car over from my wife). Driving along my normal roads I can tell my gliding is longer even at 32 PSI. I will report gas mileage and general comfort over time. As far as price. Tirerack has them for $73. After shipping they were $84 a piece. Discount Tire wanted $92. Manager beat the Tire Rack AFTER shipping price by charging $80 a piece. After a $50 rebate the price per tire is $67.50 a piece plus tax.
