    At the suggestion of F8L I am opening a Thread on LRR tyres (low rolling resistance) for the UK/European Prius vehicles. F8L has been of invaluable help to us all in the area of tyers, "and much more".

    Unfortunately the information on US tyres does not always apply to those here wishing to get the best out of there Prii and there tyres.

    I cannot even hope to emulate the work done by F8L, but will do my best to follow his good work in Europe.

    I will start shortly with a list of tyres for the gen2 following I hope with all the other Prius variants. Your contributions would be greatly appreciated and I will answer any queries you have to the best of my ability.

    (Edit) 27/4/2014.
    For 195/55/16 tyres go to post (8)
    For 205/55/16 tyres go to post (19)
    For 195/65/15 tyres go to post (26)

    As many of you will know Tyres sold within Europe now must have displayed at the point of sale "usually in the form of an attached lable" certain attributes of the tyre. These being:-

    (1) The tyres (RR) rolling resistance rated (A to G) the lowest rolling resistance rated (A)
    (2) The tyres wet grip rated (A to G) the best grip rated (A)
    (3) The amount of noise the tyre produces in DB (decibels) the higher the DB the more noise the tyre makes.

    It is important when looking at any tyre in the lists following for prospective purchase, all the details are followed this includes the speed rating designated by a single letter (eg h, s, t, v) and the load rating usually numbers (eg 87, 91 but can also have the addition XL "extra load") as both designations on the same named tyre can and does affect the RR, wet grip, and noise.

    Example:-
    Goodyear Excellence 195/55/16 speed V, load 87, gives:- RR (C), wet grip (C), noise 68db.
    Goodyear Excellence 195/55/16 speed H, load 87, gives:- RR (E), wet grip (B), noise 67db.

    As you can see two very different sets of results for the same named tyre.

    It does get you that way. I did intend putting this in the gen2 forum but as it will apply to all models i do not know where it should go. (Asking for trouble there):)

    Look forward to your further posts - particularly interested in info on 17" options.

    195/55/16 tyres. In this size I can find no tyres better rated than (C) for RR. I have listed them in no particular order of preference and not gone below this rating. There are more at this rating but I have ignored tyres with poor wet grip. This is not an exhaustive list. Other tyres will be added as found or notified.

    Details in order:- Speed letter/Load/RR/WG/Noise db.

    SIZE 195/55/16
    Michelin Energy Saver +
    V 91 C A 70
    V 87 C A 70
    H 87 C A 70

    V 87 C C 69

    Dunlop Sport Blue Response.
    H 87 B A 68
    V 87 B A 68

    For those people running 195/55/16 tyres on there gen2 Prius and intending to change all 4 tyres I would seriously suggest considering going to 205/55/16 size. There are a number of reasons for this:-
    (1) The 205 size generally has a lower rolling resistance "more mpg".
    (2) They are cheaper. (by as much as 20%)
    (3) There is a much greater choice of tyres in this size
    (4) They considerably improve grip and vehicle stability.
    (5) The speedo becomes more accurate "still reads about 1 to 2mph fast at 30mph".
    (6) The MFD fuel consumption readout becomes reasonably accurate (no need to calculate)

    As an example of cost saving going to 205's from 195's on the Dunlop tyre saves £23 on each tyre of the same rating.

    Downside:-
    The oddo under reads your millage by about 2.8% depending on your tyre choice. So remember when calculating your mpg to add 2.8% to your millage.

    Regular Energy Saver (not PLUS). Also 195/55/16

    Michelin Energy Saver V 91 XL C A 70
    ~ V 87 E A 70
    ~ H 87 E A 70
    ~ T 91 XL E B 70
    ~ T 87 C B 70

    Found here, but it is confusing, as there are two H 87's with E A and E B respectively...

    Googled which one I should get (need 2) and found this brand-new thread :)

    Sorry something wrong with format. I type it out as a list and when I post it jumbles it all.

    Working on it.

    I wonder if this should be a sticky in the International Owners section? I know I'll be searching for it when the time comes for some new tyres later in the year. A list of LLR tyres with ratings for grip and noise and approx prices would be ideal. I didn't realise the Bridgestone ER300 Ecopias were a badly rated as they are, as well as being noisy.

    With info to hand I'd rather pay a couple more quid for a better tyre, esp considering they'll be on the car for 30,000 miles.

    I'm deliberating the load rating...
    The car is some 1500kg all fuelled up? So a 87 loadrating leaves you 680 kg. I often have close to 500kg in the car, so just to be safe go to 91 rating? (320kg extra loading capacity, never going to use it, but headroom isn't a bad thing given the forces during cornering and braking???)

    Or am I seeing bears where there simply aren't any? (Difference is 11€, 9£ or 14$ per tire)

    Edit: just looked up the weight, and I guess it is hardly 1400 all loaded up, so 780kg for me and the passengers should be enough. The official loadrating is far less iirc.

    Those tyres have an (E) rating for economy but an (A) for wet grip. The best fuel economy with grip I can find is Hankook Ventis Prime 2 K115 rated (B) for economy and (B) for wet grip. There are no tyres with (A) rating for economy in this size.

    Thanks for working on this, John.

    We can work on the format as we go. I plan on making changes to my thread to attempt to make the subject less confusing for those not interested in specific. :) I.e. just tell them what to buy. lol

    Have you found a way to present the information as typed. I set everything out neatly in columns and when I post it it comes out all jumbled see post 8. If I go to edit the post it appears in the edit box as I typed it. "annoying":mad:

    There must be an on-line user friendly list of tyres, here is one closest I could find, you can chose almost any tyre that exists in Europe market:

    CONTINENTAL EcoContact 5

    MICHELIN Energy Saver +

    MICHELIN Energy Saver

    GOODYEAR EfficientGrip

    I will brobably buy Conti EcoContact 5 195/65 R15 91H, I already have Conti WinterContact TS830 195/65 R15 xxx for second winter and I am very happy with them.

    Does anybody know how do they test tyres for this energy label. As far as I know test is performed by the tyre manufacturer but at what tyre pressure and what load? Normally tyre pressure is specified by the car manufacturer and this specs are very different and not so much in line with car weight.

    RP if you need to keep cost down and want to stay with Michelin look at the "Energy Saver S1" T 87 same price as the tyres you quoted to me but better economy rating of (C) and wet grip (B) against your choice (E)(B).

    205/55/16 tyre size details. Although not an OEM fitment size for the reasons given in post 8, I include this size. Only tyres with the lowest RR shown. This is not an exhaustive list. There are no tyres in this size with a higher rating than (B) for fuel economy apart from the Bridgestone rated (A). Other tyres will be added as found or notified.

    (Edit) 24/4/2014. Found an A rated tyre for fuel economy. This is a Goodyear EfficientGrip tyre (not the performance version). It is a Fiat OEM tyre that is available designated FP FI. It is also one of the quietest tyres I can find rated at 67db.
    (Edit) 27/4/214. Kumho now make a LRR tyre.

    :ROFLMAO: I manage to get even more confused... Don't know if the country you're in has influence on where you land clicking the link*, but it was supposed to link to a "Energy Saver plus" which has (C) economy and (A) wet grip. I assume (, but don't know for sure,) they are internationally used ratings.

    Price is not the biggest issue (I'm used to motorcycle tyres lasting <10000 miles and costing >500$ a set:cry: ), but once a choice has been made, I will find the cheapest supplier.


    *: I mean the link in the private message. The link in the quote you replied to in the post above seems to malfunction somewhat.
