    I know in Florida you can't drive off without a tag. They give you one to put in the window or where the plate
    goes. Not sure about other states.

    Where is the tire list and conversations about lrr tires? Why is this thread out of control?

    Mendel said in another thread that everything off topic in this thread is all “connected.” Somehow an entailed explanation wasn’t provided :LOL:

    False 195 is not the correct size for a Gen 2 and 175 is a size down for Gen 2
    175’s are normally on a Prius C

    Just adding to this thread.. I purchased *another* Gen3 recently, and it came with brand new Blizzaks... thats nice and all, but in Michigan, we definitely don't roll around on snow/ice tires year round! So I began my search for the same tires (see below) I have purchased for my Volt's and other Gen3's many times, but found that:
    * Michelin Energy Saver A/S - Discontinued
    * GoodYear Assurance Fuel Max A/S - Discontinued

    I could not find that either Michelin or GY replaced the tire with a side-by-side equivalent. I really prefer a specific LRR energy saving tire, not the Michelin Defender or Michelin Primacy that way down on the list of its positive attributes states that it is made with some portion of LRR tire compounds that make it possibly susceptible to decreased fuel usage :mad:

    Anyways, kind of bummed. I really enjoyed those 2 tires on my hybrids/Volts. Anybody find any good equivalents to the Energy Savers/Fuel Max Tires?

    I'd go for the Defenders, what's the suffix now, T+H? Defenders used to be badged "Green-X", but now it's "Total Performance". Not sure there's an iota of difference to their rolling resistance. My take: they're not the best for rolling resistance, but they're no slouch either, and they have a good record for longevity.

    Seems like rolling resistance is a crap shoot with any of them these days. Maybe there's more outsourcing of manufacture, and quality control is not what it used to be??

    Michelin Energey Saver is $163x4=$652
    Douglas is $51x4=$204
    Diff: $448
    40,000miles/40mils/gal=1,000gal gas over life of tires
    1,000gal x $3/gal=$3,000 gas over life of tires.
    $448 is about $500. $550 is 1/6th of $3000. Will Michilin Energy tires make my car 1/6th more efficient to pay for themselves and break even? 1/6th is 16%. Given that tires use of to 7% of the car's efficiency, no way. I'm sticking w Douglas tires.

    I know and what's really funny is those tires are made by Goodyear.

    Can we use a 205/55r15 on stock rims?

    Is there any consensus on the highest MPG/lowest rolling resistance tire for a 2010 Prius II in the stock size (195/65-15) available in the USA, now that the Michelin Energy Saver A/S has been discontinued and unavailable in that size? I am on my second set of Energy Savers and I have been pleased with them but they will probably need to be replaced within a year. I have been getting 51-52 calculated MPG.

    Although several Michelins have the "Michelin Total Performance" LRR badge, the relatively new Michelin Primacy All Season (not to be confused with the Premiere A/S, the Primacy Tour A/S nor the Primacy MXM4) is marketed on Michelin's website with Low Rolling Resistance as the first point. None of the other Michelins in 195/65-15 size have low rolling resistance in their bullet point list of top features. The Energy Saver (still available in other sizes) is listed as "Ultimate Fuel Efficiency" so presumably the Primacy All Season has higher rolling resistance than the Energy Saver but lower than other models. The Michelin website seems to have eliminated the 1-10 numerical rating for the various tire features, making them more difficult to compare. Does anyone have any experience with the Primacy All Season? Is it a reasonable successor the Energy Saver?

    Buy Michelin Primacy All Season Tires | Michelin

    I am open to any brand. I do not really care about anything besides highest MPG/lowest rolling resistance and the tires actually being obtainable.

    Thank you for any advice.

    My experience is that current generation Ecopia are the lowest LRR in the US.

    Continentals for me at least aren’t as low rolling.

    Of discontinued tires
    Goodyears LRR and everybody’s nightmare tire The “Integrity” both had the lowest rolling resistance despite potential bad performance

    There’s a slew of Ecopias. And, THREE iterations of EP422 plus. I used to sing the praises of EP20, but I believe it’s gone.

    I got those, labelled Green-X, and my mpg TANKED, for the first half dozen tanks, “kinda” came back after that.

    You are only as good as the last product you sold me. With the world the way it is these days it will be hit and miss on quality for any tire.

    I still prefer the Japanese owned tire companies, but each product is unique to say the least. One good experience does not make a trend, but SAMS Club and Tire Rack reviews are a good start!

    Walland had 195/65r15 Ecopias on clearance Bought a set of 4, the 2 on the rear are a different tread pattern than the front.

    Braking and handling are fine, fuel economy is better as compared to the somewhat mediocre Michelins I had before.

    Sadly the US (unlike Europe) has moved away from LRR marketing and seems to focus on treadlife and noise.

    Our law that was supposed to place NA tire efficiency ratings has been kicked down the road going on 10 years.

    Makes you wish Euro spec tires were easier to source

    I guess I will try out the Bridgestone Ecopia EP 422 Plus at Costco. I will have to make sure that they all have the same tread pattern.

    The Continental TrueContact is highly rated on TireRack but like Michelin, their website is mealymouthed about LRR. Continental uses the "ECOPlus" designation which, according to Continental, encompasses LRR, along with wet braking and tread life, similar to Michelin Total Performance, which is also a label that includes those three features, so LRR is a factor but "balanced" with the other features.

    My Prius came with EP 20 from the factory. They gave me about the same fuel economy as the Michelin Energy Saver A/S but the EP20 lasted only about half as long. I have not seen one available for some time.

    Treadlife and wet braking seem to be the priorities with LRR in third place at best. LRR is not important to Americans because despite the complaints about gas prices, they are still low by global standards. A LRR 2% improvement in fuel economy will show up on the Prius as a 1 MPG improvement, which we would notice. On a Ford F150, 2% would be about 0.3 MPG,.

    I did the math on this a while back on another thread and found that it was a waste of money. You're actually better off getting Douglas tires from Walmart for a lower price. The money spent on tires cannot be recouped with low relling resistance stuff. If you don't believe me you could do the math here and post it to show us
