    When looking for a Prius, I had my sights on a "touring edition" because it had bigger wheels (16") as opposed to the "regular" Prius (15").

    The Touring edition 16" are low profile (/55). I see the regular Prius 15" tires have more sidewalls. I've seen parked in the area with tall 15" sidewalls. Wondering if the 15" Prius high sidewall tires are the same overall size as the low profile 16"?

    I would rather have more sidewall to absorb the bums. I can feel the harsher low profile tires.

    1. Are the 15" rims the same bolt pattern as the 16"?
    2. Is there a 15" tire with higher sidewalls that would make it as tall as a 16" low profile 195/55/16?
    3. Has anyone done the conversion from 16 to 15 and got the same overall size the same?

    Thank you,
    emb

    All of the factory sizes are the same outside diameter, overall. As the wheel gets larger in diameter, the sidewalls get shorter

    15” wheels offer the softest ride and the best fuel economy: 15” wheels are the lightest, 16” and then 17” wheels are heavier and heavier yet.

    Shorter sidewalls tend to corner and brake better, while they are more susceptible to wheels being damaged by curbs and potholes.

    Factory sizes:

    195/65R15 = 15” tall wheel. 5” tall sidewalls. 25.0” tall.

    205/55R16 = 16” tall wheel. 4.4” sidewalls. 24.9” tall.
    215/45R17 = 17” tall wheel. 3.8” tall sidewalls. 24.6” tall.

    The factory tires size also gets slightly wider as rim sized increased, but that is a separate topic. To keep things simple, I mentioned factory tire sizes only.

    If I go to a wrecking yard and get wheels from a Series 2 Prius with 15", is the bolt pattern the same as the 16"? (will they fit my car?)

    P.S. This is azaming. You think the 16" wheels are larger, but end up smaller. You think HID lights are better, until I go to the store and get quoted $800 for 2 ballast and 2 headlights.

    Thank you

    Second and Third gen wheel definitely swap. So should a Corolla, a Yaris, and some Subarus. Anything with a 5x100 bolt pattern. (5 wheel studs on a 100mm diameter circle.) Camry and other Toyotas bigger than those three smaller cars generally do not fit.

    HID lights are definitely much better than conventional Halogen, but the factory toyota stuff is not very reliable. There are cheaper aftermarket options like those from Morimoto which are brighter, far cheaper, and last longer.

    Rims sure got expensive since the last time i bought them.

    I was thinking, instead of getting the 195/65/15 to get the larger wheel, just get a 195/60/16. That way I can get the larger, more accurate wheel size without having to buy wheels.

    Would be nice to have tire size match constantly with the size. Talked to the tire guy and he said you can have tires all the same size and each one can be quite a bit different in size.

    So that means I can get a 195/65 that is lower then a 195/55.

    People say that you get better gas mileage with the 15 then the 16's because they thought the 16 was heavier. I think it's because they're smaller.

    Back in the 80's, I had a friend who had a car with 15" wheels. He put 13" mag wheels to lower it. The car would handle and corner better, but it got way less gas mileage. In my experience, I think the 15" gets better mileage is because they're larger. The 16" gets a couple miles less because smaller tires spin faster.

    If I can find a 195/60/16 with higher sidewall then my 195/55/16 I can test out if that is correct.

    I can get Prius wheels that have stamped on the inside,
    "made in the USA (thought it was Japan?) 15x6.0 LD JJ DOT CT&W 1 27 2012. Looks like the last numbers are made in 2012. In 2012 they came with 3 different rims. Two are spoke looking and one, these are solid with circles around them. From what you said, these should fit?
    Being these are the more solid mettle, seems like these are not the best that came that year.
