Melbourne Fl Prius II Bridgestone Ecopia 89S 195/165/R15 just purchased car last Tuesday 2010/08/17 Max tire pressure stated on sidewall 44 PSI
I just got my Prius IV and it had Bridgestone Ecopia's. They seem to be quieter than the Yoko's on my wife's IV.
Picked up my leased 2010 Pkg IV w/Nav in San Francisco on 8/31/10 w/a set of Bridgestone Ecopias on it. Better than the tires that came on my 2006, but do not corner that well.
I took delivery of my new Prius IV last Saturday fitted with Yokohama AVID 33S tires. However, after reading through lots of tire threads, today I swapped them out for Hankook Optimo H727's. My goal was to find a better all-season tire that would have decent snow and ice performance for our Chicago winters!
Soon to be a new owner of a IV her and the tire are Bridgestone Ecopias. I plan to change them out...not really impressed.
Model V with Nav, and took delivery on 9/6/10 with Bridgestone Turanza EL400. Don't seem to read any positive reviews so once they are done, i will change them out.
Got my red 2010 in July--Bridgestone Ecopia's. Also, they were filled with N2, but they didn't try to charge me for that. Mine came from another dealer, so I didn't know about the N2 until I went to pick it up.
My III has Bridgestone Ecopia EP20's as well... Not too bad, I filled the fronts to 40 lbs and the rear to 38 lbs, they ride pretty well... Problem is most OEM tires are not the best, you just try to run them as far as you can and then replace them with something better...
I've got a loaner while my windows get tinted. It has the Yokohama tires and they seem to be significantly louder than the Bridgestone's I have on mine. Kind of glad I have the Bridgestone's now...
Toyota begining july no longer installing expensive Yokohama tires on Prius, mainly to cut the cost!! If you purching new prius and you want Yokohama tires; you need check date of production (before July 2010).
