    The ProContact with EcoPlus is not available in the size he is interested in. :) It's a great tire though.

    The reason i am going with them is purely based on recommendations frm one of my friend (not a prius owner).... I am exploring the michelin A/S Defender for now since they look fairly priced and highly recommended in this forum.

    You should look for tires available in your desired size. Looking at anything else is a waste of time. :)

    Then you should go with a 205/50/17 or a 215/45/17. 225 is too wide unless you are building a race car. :)

    Reading all this model names, only M Energy Saver sounds familiar, that seals also in Europe, but what does A/S mean, all season?
    Germans have a very good habit of testing everything, and from your writing and different tests, I would say that Continental came up with very good compromise. Do you get ContiEcoContact 5 in US, from tests here it has the lowest rolling resistance (kraftstoffverbrauch), sadly it wasn't tested in Prius size but it is available for 195/65R15:


    ADAC Test - Sommerreifen 2012 - 165/70 R14



    Continental Tires -ContiEcoContact™ 5

    Will see what this new labeling in Europe will bring, I hope that not all tires will be labeled A for fuel consumption.

    So far we have close to 2,000 miles on the Bridgeston Ecopia EP422 tires, 195x65x15 size.
    Yesterday my wife and I took a trip up to Cabelas in Lacey Washington and we returned home with an indicated
    average mpg of 56.5. Speed ranged to city speeds up to 70 + MPH on Interstate 5 in Washington.

    Calculated mpg would be 53-54 mpg. I believe the same trip on the Michelin Energy Saver would
    have achieved indicated 57-59 mpg for the same type of driving. But they were well broken in with
    over 60,000 miles.

    One thing for sure they appear to be more fuel efficient than the original Yoko Avid tires.

    I still have about two weeks to go as I have a 30 day money back guarantee
    on the tires, if I don't like them I just may go back to the Michelin Energy Saver
    AS tires.

    Ok, so here are my choices that I have shortlisted.
    1) Bridgestone Ecopia EP422
    2) Michelin Primacy MXM4
    3) Continental ContiProContact
    4) Yokohoma Advan S.4.

    Now there are some tires that I like but i am not considering them. Again, my choice is All Season Performance with good handling and traction. I dont like the stock Yokohoma because the only thing good about them is MPG. A Quiet Tire with good handling and traction would be great.. MPG is a plus but I avg only around 45-46 in my 2010 Prius (I am always on the gas pedal) i can still live with a small drop... Thanks

    Have you considered the new Bridgestone Turanza Serenity Plus? By the numbers, it looks like a good LRR with low road noise.

    Gasped, those tires look good in that test. We don't get them here in North America. The closest we get is the ProContact with EcoPlus and they are inferior to the Energy Saver A/S in fuel economy but better for braking and handling.

    A safe bet is the Primacy MXM4. The Ecopia may be better for fuel economy but my money is on the MXM4 for handling and braking distance. Noise is low on both tires and each has decent treadlife for a 17" tire. Just be sure to get the rebate for either brand. It makes them a great deal! Just remember you will lose quite a bit when going from a 15" to 17" wheel.

    I have yet to see any reviews for the new Turanza which would help me place it among the known 17" LRR tires. The tread wear warranty is outstanding for a 17" tire and they are priced well, especially with the rebate. Only available in the 205/50/17, however, that size would be my choice for efficiency, looks, and comfort. I would likely choose them over the Defender, EP422 and Ascend if I wanted sportier handling while retaining decent fuel economy. They are a grand touring tire after all.

    Updated the list to include the new "Bridgestone Turanza Serenity Plus" LRR grand touring all-season tire. It comes in most Prius sizes except GenII and c models. This looks like a more refined and comfort/handling/long wear option instead of the Ecopia EP422. It is competitively priced except for the 235/40/18 model. It looks to be competitive with the Michelin Defender and likely better than the Yokohama Ascend.

    I'm really intrigued by this tire as well. A review I read compared it favorably to the Michelin Primacy MXV4:

    Bridgestone/Firestone Tire Test - Motor Trend
    I like the fact that it comes in the 205/50/17 as well. I would love to see how fuel economy compares to the dedicated "Eco" tires. Maybe the smaller contact patch will make up?

    I just talked to a sales guy at Discount Tire about the three tires noted in the two post above. Interestingly, the guy believed the Ecopia would be both longer lasting and quieter than the Turanza Serenity Plus -- as well as better as an LLR tire for economy. I told him this didn't make much sense to me. He told me he had just gone through a driving comparison with the Serenity Plus tires and thought they were great tires, but he believed the Ecopias would be a better fit in terms of noise, wear and fuel economy. Of course, he felt the Michelins would be the tire to pick among the three, unless my number one interest would be MPGs (in which case the Ecopias would be his choice).

    I know F8L's recommendation is going to be the Primacy's, but I'm interested in a general reaction to the salesman's statements. (Also, the quoted prices among the three tires didn't show enough dollar difference to cause me to choose one over the other.)

    BTW, I would rate safety, noise, fuel economy and wear in that order, as my interests.

    I believe the tire guy is right. The Ecopia EP422 is likely the best for fuel economy and possibly noise. The Serenity Plus is a very heavy tire with a lot of tread depth (12/32) and it is designed as a bit more sporty for the luxury car crowd much like the Primacy MXM4 is. IMO the Serenity Plus is more of a competitor to the MXM4 than the Ecopia. From a safety standpoint I would chose either tire over the Ecopia. I would choose the Michelin if safety was my biggest concern. It has been thoroughly tested and it did quite well. I've driven it and while not the stickiest tire I've ever ran it did instill confidence. The wet braking is outstanding. The wet braking on the Ecopia was not so great according to TireRack tests.

    See this test to compare the older Turanza Serenity with the Primacy MXM4

    Then look at the stopping distance for the Ecopia EP422 in the same exact size on the same exact car.

    Very helpful, F8L. Thanks.

    I'm a pretty defensive driver and safety is important to me. I'm wondering whether driving 59,000 miles on the Toyos has been throwing caution to the wind, at least in comparison to these three tires. If I can get similar fuel economy out of the Ecopias, yet have a step up in safety and control, as well as a decrease in road noise, perhaps that is the tire for me. I'm not a slalom driver, and I don't play Formula 1 racer in a morning commute. I want to go somewhere in safety and reasonable comfort and quiet, all while getting 50 MPGs. If my best bet on these counts is the Ecopia, as opposed to the Primacy or the Serenity Plus (which suggests incontinence safety), you may have given me just the right assistance.

    I'm not sure if I was clear or not but to rephrase myself. From a safety and comfort standpoint I would go with the MXM4. The fuel economy is decent. I was getting 52-55mpg while I had them on my GenIII and that was before I got really good at driving it. AZGeek is averaging over 50mpg as well. I think he even got a 59mpg tank.

    The only reason I would purchase the Ecopia over this tire would be for the price and/or fuel economy.

    The only reason I would purchase the Serenity Plus over this tire is for the price. I did notice that another reviewer compared the Serenity to the MXV4 but slightly better. The MXV4 is a great tire if a bit dated. So the Serenity Plus should be good.

    I think you were clear enough. What you are reading is my musings about each of these tires being significantly better than my Toyos and that if the Ecopia is better in all ways and is still a high FE tire, then it may be the tire for me. I haven't felt unsafe driving the Toyos -- just a bit annoyed at the noise. If the Ecopias will give me a safer drive, better performance, and similar fuel economy (as compared to the Toyos), then they may be right. If I can get the Michelins at a lower price, I'd only walk away if I was going to lose 4 MPGs.

    (You seemed to move between the MXM4 and MXV4 -- just a typo? I think the Vs are for higher sidewall tires, right?)
