    I got 195/65/R15 tyres at the moment. Would that fit the current wheels? Bit of a novice here when it comes to tyres. I usually buy the cheapest I can find but want to do my little Prius proud.. and safe some petrol :)

    And why can't I find the Michelin Energy Saver A/S tyres they are always talking about here. Are they US only? I will be passing through the UK on the way to the Netherlands next month, btw..

    Sorry I was forgeting I was in the gen3 not gen2 forum. In that case see if you can find some Bridgestone Ecopia 001S tyres, only made in your size and the only tyre rated AA. When I reaserched them they were not expensive and you would easily recover any extra cost with the MPG gained.

    Michelin A/S are not available in the EU.

    Thanks for the advice.. will let you know what I get.. I will have to shop around for these.. price differences are huge.. if I can safe €10 per tyre that's a lot when you replace 4..

    Yes I know what your saying, but if you only get 2 MPG more with the better tyres over the life of the tyre say 30,000 miles thats 18 gallons of fuel at £6-40 (UK PRICE) = £115-20 saving.

    How much is fuel in Ireland now.

    Very true. I just can't find any A rated tyres so far online here in Ireland. Search is on going..

    The only A rated tyre made is the one I quoted in my previous post and that is only made in your size.

    If your trying to keep outlay down have a look at the Hankook Eco Kinergy tyre in your size rated BB 69db.

    Found them! And not a bad price either. Local Advance Pitstop quoted me €100 for Continental tyres. These are about €20/tyre cheaper. Geez...

    Our freinds in the US are dying to get hold of these but they are not available there yet. I've got to wait till they come out with my 16 inch wheel size either 195 or 205.

    Let us know what you decide and have you checked out the Hankook's.

    Hankook's are BB rated and about €20 cheaper per tyre. Very good price and rating. Would it be worth the difference. I would like a quiet ride as well. Roads here are crap so road noise reduction would be good. I won't be buying anything tonight but will decide next week when I get paid again.

    I use the Hakooks myself had the on for 20,000 miles and look good for another 20,000. I am using 205/55/16's on my gen2 Prius and find them very good for grip and low noise.

    They came on my previous car (not a Prius) as OEM and I was impressed. When I needed tyres for my Prius I checked them out and thought they would be good on the Prius.

    This was before the rateing system came out but when it did it confirmed my choice.

    I appreciate the problems with cost outlay against long term costs with an AA rated tyre. If it were me I would go for the AA tyres, but I can aford the outlay, and I do understand £100 saving or there abouts on the less expensive tyres has it's attractions, only you can decide.

    Give me your fuel prices in Ireland and i'll do the maths based on a gain of 2MPG at todays fuel prices (remember if fuel goes up) the savings will be more.

    Currently petrol is €1.61/Liter.. Another site is selling the Hakooks.. The 91H rated ones are just €55/tyre.. that is a good bit cheaper.. Bridgestone Ecopia EP001S are €80.71.. Wonder how well they would perform compared to the Hakooks and would the extra €102.84 be worth it..

    Primary concern for me is wet grip (lots of rain and bad roads here), noise reduction (for the same reason) and durability. If I knew the Bridgestones would last longer I would buy them but I can't seem to get any reviews up. Anybody out there have these to compare? I do 20000 miles in a year and was hoping to get more than that out of tyres.

    The reason you cannot get any feedback is that they are to new and are difficult to get hold of.

    As long as your car is in good order (wheel alignment etc) there is no reason why they should not last at leased 30,000 miles. I can vouch for the Hankook's as my car is now at over 90,000 miles, and expect to make it to 110,000 at leased on them.

    Noise level is given the same for both tyres at 69 db and I found my tyres very quiate compared with the OEM
    Turanzas ER300.

    I can see where your coming from on price the difference would buy two more tyres. I'll do some sums based on the tyres lasting 30 and 40k miles at 2mpg difference.

    Based on the tyres doing 30,000 miles at +2 mpg works out at 168euro - 102euro (price dif) = 66euro saving.
    Based on the tyres doing 40,000 miles at +2 mpg works out at 227euro - 102euro (price dif) = 125euro saving.

    The brake even point on the two different tyres is at just under 20,000 miles = no saving, below this the Hankooks are cheaper

    This is a reasonable estimate of the saving between an A and B rated tyre at 1.61euro per ltr of fuel.
    Hope this helps.

    Thanks John. Think I will give the Hankooks a go. The tyres that are on the car (bought used) were not standard and very cheap. They had been replaced recently probably to sell/trade in the car. They have lasted me only an aditional 15000 miles. Not sure what the ratings on them are. I find the tyres noisy so these will probably sort that part.

    Thank you for your help. Never knew you can get lost in the detail of tyres! :)

    Since there so many anal people on this site-I will throw this out. On my 2013 Prius II, the OEM tires areGoodyear Assurance Fuel Max Made in Japan. They have a different rating 540 vs 580 and the max pounds are 44 versus I think 50 pounds for US made. since Goodyear Japan is made by Sumitomo- HoW would they compare? ALso different speed rating (S). So what is it, any ideas/ THANKS

    It is likely you are seeing a difference between the Toyota spec version of the tire and the Goodyear spec on the aftermarket tire.

    An auto manufacturer often works out a contract with a tire manufacturer to build a tire with specific qualities they desire for their model of vehicle. This is especially true in the case of fuel economy where every manufacturer needs to eek every last bit of efficiency out of a vehicle for certain automotive standards and regulations such as CAFE. So in a lot of cases, the manufacturer will contract for a tire that is more efficient and comfortable but that requires a trade off in things like longevity, grip or handling. The tire manufacturer may then decide they want to sell their own version of the tire with qualities they feel are important so they alter the design of the tire. The tire is usually close enough in design traits to qualify as being the same tire but sometimes not. The Fuel Max tire is one where there are very obvious differences. I think the biggest difference in the case of the Fuel Max is based on one tire being a different load and speed rating.

    I hope that helps. :)

    Do you mind editing your post with the quote? It's bad etiquette to quote something so long. LOL

    News:

    It appears Michelin and Bridgestone are moving in the same innovative direction towards great fuel efficiency. While this isn't hot off the press news, I did find it interesting that the top names in LRR tires are working on the same ideas.

    Both companies are working on a tall & narrow tire design that I find intriguing. This may just be the answer to the prayers of PC members who want the look and handling of an 18" wheel without the mpg hit. Exiting times!

    I noticed that Pirelli has a fairly new lrr tire in the Cinturato P7 all season plus. Has anyone tried this?

    I need new tires, prefer the 205/50-17 size, and value handling first, wet traction, then fuel economy and tread life. Price too.

    I drive on twisty roads and in the rain a lot, and like to drive pretty fast. I laugh as I type that, as I do drive a Prius, though my previous cars were significantly more sporty.

    Other tires I'm considering are the Continental PureContact and ExtremeContact DWS.
    Thoughts?

    I saw those tires but I have not heard anything about them yet. I am waiting for TireRack to test them.

    I can say the PureContact is pretty good overall. I felt they were a bit rough riding but steering response was good and cornering grip didn't feel significantly different than the Primacy MXM4 despite being narrower and with a taller sidewall (PureContact). Meaning it felt pretty good in the corners for a LRR tire.
