Since those are non-OEM tires, I would assume that the Goodyear Assurance tires are better than the Yokohama Avid S33 OEM all-season tires that most II-IV Priuses come with in N.A.
NL: Executive, Barcelona Red, Toyo Proxes A20 215/45R17; They make a lot of noise on concrete surfaces as well on asfalt will be replaced next year by Michelin Energy Saver
Yokohama Avid S33D. However I bought the Hankook Optimo H727's at Tirerack, they delivered to my dealer in one day, total cost including delivery after $30 rebate = $308, and the dealer didn't charge anything for installation. I took the Yoko's home, I have the Yoko's on sale on Craigslist, got one nibble so far, hopefully someone will buy them. I bought the Hankooks for my '04 Prius last year, and they made such a difference, especially in the wet and snowy conditions, we really wanted them for the new car too.
I think we have a pretty good database for the US cars, what do you think Danny? Do we still need more input?
