Another vote for the Nokian tires. I live near Boston, Ma and we get ice and snow these tires have made all the difference in the from the originals driving in these conditions. I took a small mileage hit and now the tires are broken in and I average 49 to 50 mpg. Not bad . FishHawk
any comments with the fuel saver tires out on the market? I believe now every manufacturer has a brand with the wording, "Fuel saving max, or green tire" in it.
Here in Europe it should get interesting at the end of the year. All road tyres will be tested for fuel efficiency, and will have to display a label at the point of sale with the test giving a score in 8 bands A to H. Know tyre will be given an A rating to start with to encourage manufacturers to develop better tyres.
Its far from scientific, but I have found the OEMs to be 5-10% better in terms of fuel economy than the Nokian i3 at least in our hot climate. I had these on my car for about a year, and struggled to keep the mileage in the high 40s. My wife had the OEMs, and while she also averages high 40s whenever I drove her car I could easily get low 50s. About a year ago I swapped wheels with her, as I'm more obsessive about mileage and the family usually rides in her car. As soon as I had the OEMs back on my car I was back into the low 50s without trying very hard. When those tires were up (~45k total miles), I decided to put on a used set of OEMs (7/32 remaining) for $240 installed from a local reseller. There seem to be plenty of low mileage used OEMs around given how many people don't like them. Here in Phoenix rain and snow are not much of a consideration, so I've never really had any complaints about the OEMs. Will likely keep a more capable tire on the family car and live with the mpg hit, but for my own this seems to be the best mileage and value option.
OK - I have the need to purchase new tires for my 2010 Prius II. I need prices at a good rate, good gas mileage and durable (like everyone else). I use my vehicle as a courier. Suggestions from Seattle.
Can anyone recommend Hankook Optimo 727s? Seems like a great tire, but am unaware of how they do on gas mileage.
I would not recommend them for great gas mileage as they are not a low rolling resistance tire nor are the known for great handling. They do well in snow and they wear well, however. My off the cuff suggestion for Seattle, good gas mileage, long wear and cheap price - Continental ProContact with EcoPlus.

There is a thread here on tirerack testing where I compared MPG results of various tires. In post #31 I list the tires in order of fuel efficiency with the best at the top. The math is complicated because not all the tests were done with the same size tire but the H727 gets about 2% worse than an average LRR tire to 5% worse than the best LRR tire. I'd be happy to put the H727 on my prius if I got them cheap enough but if you drive a lot of miles you may come out ahead paying for a better LRR tire. I'll paste in a list for you:
Hi. Can anyone confirm if the GY Integrity tires as mentioned are LRR? If so / not, can you point me to materials confirming such? Thanks.

As far as I know there is no specific coefficient of rolling resistance below which tires are allowed to be called LRR (and above not). At present the use or otherwise of this description is purely a marketing issue in my opinion. One brand may use the term ULRR (Ultra low rolling resistance) for a tire yet it be higher rolling resistance than another brands regular LRR tires. That's why at present we're basically flying blind, except for some particular tires that have been independently tested. Dhanson (above) has done a good job of collating the data from available tests to at least put a subset of candidate tires into approximate ranking. It's a bit like that with flashlight batteries (and some other products) here in Australia. They don't have to disclose the amp-hour rating and (annoyingly) are allowed to instead use meaningless superlatives. There's absolutely no guaranty that brand-A's super-extra-ultra-mega-heavy-duty battery will last any longer than brand-B's standard duty battery. Unlike real quantitative ratings these "marketing superlatives" are essentially useless in many cases. I've heard that tire manufacturers will soon have to place an actual meaningful rolling resistance rating on tires marketed as LRR. The sooner the better in my opinion.
I've had Continental ContiproContact LRR tires on my 2008 Prius Touring for about a year. Not a bad tire, but they do seem to show quicker wearing down than the OEM tires (Bridgestone I believe). I drive about 18k miles per year in my Prius with a 70/30 percent time split of city/hwy driving.
