    I plan to buy the new 2023 Prime, but I am torn between the SE and XSE. If I choose the XSE with 19" wheels and later decide to change the wheels to 17", can I put 2023 17" Prius, or 17" Corolla, or 17" Prius aftermarket wheels on it, or will they be incompatible? What's a good site find a good selection of cool, compatible Prius aftermarket wheels?

    Older generation Prius or Corolla OEM 17" wheels will not work on new Gen5 Prius or PriusPrime. They have different bolt patterns. Older Prius and PP and Corolla are 5x100. Gen5 Prius and PP are (PCD): 5x114.3 (5x4.5). The Prius V had the same bolt pattern and came in a 17" size wheel. It may fit. But, there will be plenty of aftermarket wheels that will work, I think.

    You can read this thread. Anyone can confirm bolt pattern on 2023+ models? | Page 2 | PriusChat
    The new Gen5 Prius and Prius Prime use 17/6.5J 5x114.3 with a 40 mm inset OEM wheel for 195/60R17 stock size 17" tire. The hub opening is reported to be 60mm by a Japanese Toyota publication. But IIRC, the older Prius I had (Gen3 and Gen4 PP) in the past used 54.1 mm center hub. So, any wheels with a smaller than 60 mm center hub hole are not going to fit. Aftermarket wheels have an oversized center hole and you can use a hub ring to make it hub-centric.

    According the Toyotas published specs, the XSE weighs 55 pounds more than the SE and gets about 7.7% lower fuel mileage, possibly due to the added weight of the wheels and added features. If I bought the XSE and replaced the 19" wheels with the SE 17" wheels, do you think I would increase my fuel mileage very close the the SE?

    What else besides weight difference (55 pound difference) might impact mileage between the SE and XSE?

    I have a set of wheels from a 21 rav4 that are 17" with the correct bolt pattern I have nokian studded snows and they will fit.

    You will need to calibrate the speedometer downsizing the wheels & tires because the 17s are a tiny bit smaller than the 19s.

    This is not necessarily true, it will depend mostly on the tire's outer circumference, not on the rim size.

    There are tire size calculators online and apps that can do the comparisons between wheel/tire sizes and let you know of any differences. It will tell you the difference in speedometer and odometer reading with the tire sizes compared to the stock/oem size.

    Definitely not true, lol. Regardless of wheel size, the outside diameters of the various tire/wheel options will be reasonably close, by design. There's no practical way to "calibrate the speedo" anyway.

    FWIW, the OD's of the two 5th gen options are more than the usual "slight" variation (comparing to previous gen's), but yeah you can swap between them with impunity.

    It's a 1.9% different between the stock tire sizes. Regulations may allow a margin of error to speedometers as high as 5%.

    yes I am aware of that. The 17 combo being smaller is also why the LE/SE sits lower.

    The difference is indeed very small. Didn’t know that they allow an error as high as 5%. Thanks for the info! It’s reasonable to believe Toyota might have not set a speedometer difference between the models anyways.

    Cant’t rule out the possibility. There are cars out there with different speedometer settings for different tire sizes from factory, even within Toyota group. Especially the one with AWD/RWD variants, staggered setups, etc.
    But what you said is most likely true with the Prius.

    Yeah, I thinking it was just +/- 3%. One source said 4% for the US, but, possibly amended, legal code says up to 5mph slower or faster when at 50mph for trucks and buses. In the UK, the speedometer can't read slower than the actual speed, but can read 10% high.

    As long as you are staying within the results of a Plus X calculator for different wheel and tire sets, there is enough fudge factor in the speedometer accuracy to not worry about recalibrating it. Also easy these days to check against GPS.

    Yep I have a set of 17" (225/65R17) from my NX 300h that would fit. They may stick out a little because they are wider and have a smaller offset so that would affect gas mileage probably as bad as the 19".

    The two stock tire sizes for 5th gen:

    195/60R17 (26.2" OD (Outside Diameter))
    195/50R19 (26.7" OD)

    Your prospective tire:

    225/65R17 (28.5" OD)

    Comparing to the stock 19" OD: 6.7%. Also will raise the car, by almost an inch.

    If he changes to a 215/55-17 the diameter falls in between those two. The Michelin Cross Climate 2 is 26.3”.

    Yes. The added weight of the vehicle has negligible impact. It's all about the wheels.

    The wheels are likely a good part of the added weight. That happens to be in the worse spot to add it.

    Have increased stopping distance from smaller brakes?

    Someone suggested Camry Hybrid 205/65/16s and I really want to try that. The rotor sizes between Camry and Prius are the same, so the wheels ought to clear the brake hardware.
