M3 wheels to a MY?

    Taking delivery soon fo a MY LR-AWD.
    We will be moving to CO this Summer and so the need for a winter set is necessary.
    We are taking delivery of the MY with 20s, however looking for a set of wheels to put winter tires on.

    Ideally, 18s would be most economical, with 18" winter tires - but would they fit over MY Breaks etc.

    MY - 20 x 8.5 +35
    M3 - 18 x 8.5 +35

    So I assume they should fit - ? and have a small change in speeds, based on tire size.

    Thanks for your help.

    Another option would be the M3 19s, which are 19 x 8.5 too.
    MY 19s are 8.5 wide too.

    Bore size seems to be 64.1 too.

    Breaks <> brakes

    Model Y 19 and 20” wheels are 9.5” wide and ET45.

    Yes, 18x8.5 ET40 Aeros should fit over the Model Y LRD rotors; they’re the same as on the 3. They’ll be more efficient than the 19x8.5 Sport wheels from the Model 3.

    Look at 245/50R18 or 245/55R18 for the closest tire fit, the former is smaller diameter, the latter is larger than the OE tires.

    I'm guessing that the brake setup on the Y is comparable with the M3P setup - i.e. only wheels that fit the M3P will fit on the Y.

    Reason is that the model 3 Gemini wheels (winter tire set for M3) are specifically available for the M3P.

    I don't know if there are any 18" wheels that fit on the M3P.

    Of course you can always go with after market wheels if they come out in 18" for the Y.

    According to Musk, the mileage loss for the PUP is due entirely to the tires/wheels.

    That’s pretty much correct, which means it’s not entirely correct.

    It’s also not relevant to this thread.

    I just learned that the base Model Y has larger front rotors than the Model 3. I do not expect the 18” aero wheels to clear the Model Y front rotors. So ignore my previous post. You got to go with 19” wheels.

    The Aero wheels clears the front calipers of Model Y. The rear, probably not - the inside radius of the wheel is about 8.4 inch and the rear break calipers is at 8.5 inch.

    My measurements was not so precise, but too close to call.

    Either way, don't think 18 Aeros are good choice anyway...19" minimum is better.

    I'm not gonna use 18 Aeros, just testing for our information...

    Thanks!
    Would you be able to test fit?
    Also, are the MYP have bigger rotors?

    I am not going to test fit the 18" Aero to the rear, its risking damage to the calipers - it's to close if it will fit at all, sorry.

    Model Y rotor size is not the problem, they will fit inside the 16.xx" diameter of 18 Aeros. They are about 14" front and 13" rear diameter on any Model Y.

    The caliper is the thing that sticks out further...and by my measurement will not clear the inside wall of the 18" Aero wheel on the REAR Model Y Calipers.

    PSA: Model Y uses new Bluetooth (BLE) 2.4 GHz TPMS Sensors.

    The traditional 433 MHz TPMS Sensors OE or Aftermarket used on Tesla Models S3X will NOT work as of the current iteration of any Model Y. Screenshot_20200412-140025_Drive.jpg

    ^ that's interesting... thanks!

    Wonder what the advantage is over the "standard" freq, or is a future industry wide trend and we're seeing it start of it here and now?

    I was wondering that as well. I can't really think of any technical reason as the 433 MHz sensors have been in use for ages and work well.

    Likely the only reason is that it will cost less in the long run. Even a $0.01 cost reduction is worth it if you buy lots of them. And on the vehicle side it may allow getting rid of one type of component (the part that communicates with the 433 MHz tire tire sensors) as 2.4GHz is also used for other tasks, this allowing re-use of existing components.

    Here's some info I just found TPMS – tyre pressure monitoring system | HELLA

    For almost all tyre pressure monitoring systems, transmission occurs in the frequency range of 433 MHz. This frequency range is also, however, used by radio devices, radio headphones, alarm systems, and garage door drives, for example. Please take this into account in the event of malfunctions with the tyre pressure monitoring system. The current development is toward small active systems without batteries (transponder technology) which are just glued into the carcass or which are integrated into the tyre. These systems operate in the 2.4 GHz range, which is not so susceptible to interference, and can record other information, such as road condition and wear state, in addition to temperature and pressure values.

    Anyone put the 19s from a M3 on the MY yet?
    Thinking of taking delivery with the 20”
    Induction wheels and also buying a set of 19s for wife to roll around in for smoother rides.
    The Gemini wheels just don’t look good- I could always get them and paint them- however, buying a separate set or 20s, will be way more than the $2k at purchase

    I guess no one had done it.

    For reference this is 20" M3 Sportwheels with 255 Michelin Pilot Sport A/S Plus - it should look like it with about +10 mm tire wall.
