    Thanks! So probably can't get them here? Whom would one trust to do a wheel/tire trade out and get it done correctly?

    First, I want you to re-read post #1 a few times...

    Then decide if you want to stay with a 15" wheel so you can use your current OE tires, or decide if you want
    upgrade to 16 or 17" wheels & tires. Once you figure this out, it will be easier to help you.

    My first post in here, just got my 2018 Prime Plus and planning to get snow tires so I got some advice from the place I am getting from.

    They suggested me to use the stock rim and put snow tires on it so TPMS in the winter time is there.

    Save the stock tires and put them in the following suggested wheels:

    Option 1: Fast 7
    Model #: F213
    Size: 15x6.5
    P.C.D.: 5x100mm
    Offset: +45
    Finish Gloss Gunmetal
    Bore: 54.1 mm
    Seat: Flat
    Lip Size: N/A
    Load Rating: 1521 lbs / 690 kg
    Winter Approved Finish: Yes

    Option 2: RTX OE Aura Silver
    Wheel Size 15x6.5
    Bolt Pattern 5x100
    Offset 38
    Hub Bore 54.1
    Weight 8.65
    Finish Silver

    Which Option would you guys recommend to use with. I like Option 1 for the finish look but not sure about the ratio/spec/weight/offset will affect any issue to my Prime down the road. And then add TPMS sensor to the new wheels.

    Or do you guys recommend me to get steel wheels + snow tires without TPMS sensor and keep using the stock tires + wheels?

    I am always afraid the steel wheels are always heavier and my suspension/control arm will be wear and tear much faster. Since Prius Prime is all about efficient and I dont want to make it heavy like a tank to get less MPG.

    Please advise,

    Welcome.

    The problem with your question is that there are so many different ways you could go on this one, this makes choosing the
    best way more difficult. Here are some thoughts:

    1) Buy new steelies & snow tires and save money by not using TPMS, if purchased today this combo could be purchased for
    as little as $420 shipped based on Tire Rack rebates.

    2) Buy & mount up your new snow tires on your current wheels, then take your time and buy a used set of the
    exact same stock Toyota OE wheels that you currently have, figure roughly ~$100+ per wheel on Ebay.

    3) Upgrade to a Plus 1 (16") or Plus 2 (17") wheel & tire, thus making your current 15" wheels your dedicated snow tires.

    There are still many more variations to this, just consider all your options carefully first before purchase.

    Thanks Rob for the recommendation and yes there are many more variations to play with.

    I do have a concern with this section:

    3) Wheel Weight:
    Less is more, meaning try *not* to buy into heavy wheels if it can be avoided. IMO this would be any wheel above ~18.5 lbs in weight; 17 lbs or less would be great. One of the big problems with buying aftermarket wheels is much higher wheel weight: higher wheel weight (unsprung weight) *negatively* affects the chassis in many ways. Poor fuel economy would probably be first, other issues will be sluggish handling, slower acceleration & braking & increased strut/shock wear.

    Either I pick a steel wheel or alum wheel, it should be 17 lbs or lighter (probably more $$) or same weight as the OE wheel as a best practice so that our strut/shock/control arm tear and wear to be minimal?

    I guess I have to get that weight information ahead of time prior purchasing.

    Please advise

    This is an excellent question, so let me clarify a bit more.

    When I talk about wheel weight, and much more importantly overall wheel & tire weight (Unsprung Weight), I am referring
    to the negative effects over a Long Period of time. When the average guy buys into a wheel & tire package, they of course will
    have this mounted for 10's of thousands of miles. Let's assume for a minute that someone doesn't do their due-diligence & buys
    into a heavy wheel & tire setup that weighs in at ~45 lbs, this is roughly 33% more overall weight when compared to the stock
    OE setup; it's this ~33% weight increase over ~50K+ miles that can potentially cause wear & tear problems that go beyond the
    expected MPG loss in fuel economy.

    In the case of an OE size 15" cheap steel wheel at roughly ~19 lbs for a 15x6", 5x100 & one of the lighter weight snow
    tires at ~19* lbs, you can expect a overall weight of 38 to 39 lbs when mounted. This represents roughly a ~12%
    to ~15% increase over stock OE wheels & tires which really isn't bad considering the added grip & safety of
    your new snow tire setup.

    Since your new snow tire setup will only be mount for a short duration of time, ~3 months & roughly ~2K to ~4K
    miles, don't be concerned with the slight increase in overall wheel & tire weight.

    Do realize though that snow tires are the Opposite of LRR Tires, meaning that your MPG will suffer when using them.
    But your new grip level & safety (confidence level) will Greatly Outweigh any loss in MPG for the ~3 months that they're mounted.


    Rob43

    * 195/65-15 snow tires typically range from 19 to 21 lbs each.

    Thanks Rob for your explanation in detail for #3.

    I got a reply from fast site and the weight for this Fast 7 F213 15" wheel is 16.40lbs (lighter than OE stock wheel).

    Fast 7
    Model #: F213
    Size: 15x6.5
    P.C.D.: 5x100mm
    Offset: +45
    Finish Gloss Gunmetal
    Bore: 54.1 mm
    Seat: Flat
    Lip Size: N/A
    Load Rating: 1521 lbs / 690 kg
    Winter Approved Finish: Yes

    Since I am keeping the Prime for a long time (assuming it is the same DNA from the Prius), I would put snow tires to the stock OE wheel and put the stock OE tires in the Fast 7 wheel (will get a TPMS that can be cloned so no need to re-program each and every time during flipping season).

    Thanks,
    NSXT.

    Hello Rob. I am not quite familiar with how aftermarket wheels will affect my Prius Prime. I am new to this. I have a few questions. I was hoping you can help me. This is the wheel I am interested in from Tire Rack:

    Andros Spec L
    Size: 17x7.5
    Offset: 45mm
    Bolt Pattern: 5x100
    Weight: 19.9

    Goal: I would like to stay as close to the original MPGs as possible while getting some new wheels.

    1.) Are those wheels too heavy? Do you know how much miles I would lose?

    2.) I want to make my wheels stand out so I was thinking about tires with a short sidewall height. Is that a good idea? What tires would you recommend with those 17inch rims?

    3.) What size spacers would you recommend?

    Any help is appreciated. Please. Thank you. =D

    My recipe for averaging the least MPG loss possible while using an upgraded Plus 2 (17") wheel & tire:

    1) Pick a smaller width 17" wheel like a 7" wide wheel, your chances of finding a lighter weight 17x7" wheel is better when compared to a wider width 17" wheel. More metal = more weight weight when all things are equal.

    2) Go with a 205/50-17 tire size (25.1") because this size is the closest to the OE 25.0" size diameter. When comparing the same Exact tire, a 205 will have less rolling resistance when compared to a 215 or 225 tire.

    3) Always pick a LRR tire that's Light Weight, there are lots of heavy LRR tires out there, try to purchase a LTW tire.

    ******************************************************************************************************

    Here are two good LTW wheel examples, 1) My wheels on post #17, 2) The link below.

    MR131 Traklite 17x7, ET45, 17.3 lbs $132 Shipped.
    https://www.tirerack.com/wheels/WheelCloseUpServlet?target=runWheelSearch&initialPartNumber=MR13177051645BR&wheelMake=MOTEGI%20RACING&wheelModel=MR131%20Traklite&wheelFinish=Bronze%20Painted&showRear=no&autoMake=Toyota&autoModel=Prius+Prime&autoYear=2018&autoModClar=Advanced

    LRR Tires:

    This appears to be a fairly LTW 205/50-17 tire at 19 lbs, it should be a consideration. ~$127 shipped each with current Rebate.
    https://www.tirerack.com/tires/tires.jsp?tireMake=Firestone&tireModel=Champion+Fuel+Fighter+%28H-+or+V-Speed+Rated%29&sidewall=Blackwall&partnum=05VR7CFF&tab=Specs

    Continental PureContact LS 205/50-17, 20 lbs, ~$137 each shipped.
    https://www.tirerack.com/tires/tires.jsp?tireMake=Continental&tireModel=PureContact+LS&partnum=05VR7PCLSXL&vehicleSearch=false&fromCompare1=yes


    Prediction: ~5% MPG loss with the above setup...

    Hi Rob,

    I'm interested in the Advan RT and they have a 17x7, 5x100 but it's 50 "inset" as they put it. Will that fit the Prime? The wheel is stunning to look at (see below) so I'm really hoping it will fit.

    And here are the specs from the Advan website:

    Send them three questions before you go any further:

    1) What's the Hub Bore ?

    2)* Is "In Set" the same thing as "ET" ? (I don't like to assume)

    3) What's the weight of the wheel ?

    Take a look at the Maxxim Winner 17x7", 5x100, ET40, 73.1 Hub Bore, 17.0 lbs by Konig Wheels, they're roughly $105 shipped.
    Maxxim Winner - Konig Wheels


    Rob43

    * IMO if these are an ET50 wheel (which they probably are), consider passing on them.

    Thanks, Rob. I'm beginning to think that the search for the perfect wheel is a bit like the quest for the Holy Grail! :)

    I would ask them if they will guarantee that they fit and put it on their lap. Wheels is what they do and they should know.

    Good advice. Especially when the wheel is a special order and likely no returns.

    Rob,

    Here are photos of a Gen 3 Prius on Ray's Super Eco 17x7s with 50 inset. First, here's a photo of the unboxing (very exciting!):

    Image 1.JPG Image 3.JPG Image 5.JPG

    And here are photos of the wheels on the car:

    Formula Silver 1.JPG Formula Silver 2.JPG

    So, if the Advan RT 17x7 is also a 50 inset, shouldn't they also fit (assuming the "fitment" is the same for the Gen 4 as for the Gen 3)? What do you think?

    Chris
