Hi all, I Just order a LR model S with 19"" wheel. I am planning to put my 21''Arachnid wheel set and tires that I received from referral couple years on the new car. However, I just notice on Tesla store that particular wheel set is shown to be compatible with 2012-2020 model S. Wondering if it is gonna fit the 2021 model, I haven't seen the new model S with the old 21'' Arachnid online yet.

Here is the response I got from a service manager.

“The original arachnid wheels would not fit the newer Model S for 2021+.

They are only meant to be installed on the original 2012-2020 Model S vehicles.

We would not be able to advise on using any spacers or anything to modify the way the wheels fit. The newer set up is wider than the previous years

Original Arachnids
Size + Offset21x8.5" +40 (FRONT)
21x9.0" +40 (REAR)
Bolt Pattern5x120
Center Bore64.1mm


The new Arachnids that come on the refresh as the $4500 option:

21x9.5 +40(Front)
21x10.5 +45(Rear)

I believe that its still Same bolt pattern and same center bore. But I havent seen anything to 100% confirm. But assuming both are the same:

Yes your old arachnids will fit the refresh. Wheels and tires will not be as wide as the new Arachnids. And the rears will sit inward 5mm more. (That is easily solvable with a good/quality 5mm hubcentric spacer).

Thanks. Sounds like it should be ok. 5mm offset difference shouldn't be really noticeable if I don't want to deal with the spacer.
