Will my 19" Breyton Race GTS wheels work on Model S?

    I'm just about to finalize a Model S order. I currently have a 2009 BMW M3, and I have a set of nice wheels and tires for winter that I'm hoping I can use on the Model S. I plan to get my Model S with the 21" wheels, but for winter I'm OK with 19" wheels. On the M3 these were configured as staggered wheels, but I'm not sure if this works on the Model S. The parlance and specs of wheels and tires is beyond me.

    Here is what I have:

    Fronts: 19x8.5 Black Painted Breyton Race GTS with 235/35R19 Bridgestone Blizzak LM-60
    Rears: 19x9.5 Black Painted Breyton Race GTS with 255/35R19 Bridgestone Blizzak LM-60

    I think these are 5x120 bolt patterns.

    Can I use these on the Model S? Do I need spacers? I needed spacers for the rears on the M3.

    The bolt pattern is the same for both BMW and Tesla (5x120) so you're ok there.

    One of the key specs you should have is the offset of these wheels. That will help in knowing if they will fit. I would guess they are +35 which will probably work.

    235/35 has a fair bit smaller rolling diameter, so your spedometer is gong to read quite a bit high. I just ran the #'s through a tire calculator and it will be high by ~8% THis also means that your top speed etc. will be 8% slower as well.

    Upon farther research you won't be able to use these tires, however the wheels might work. The load index on the 235/35 Bridgestone LM-60's is well below what the Tesla needs. Their load index appears to be 91 while the Tesla OEM tires are rated 96. (This is a carrying capacity difference of >200lbs per tire.)

    Thanks so much for the info.

    I hope I can use the wheels then. It would be a matter of finding comparable tires.

    I've tried emailing tire rack but no response.
