Aren't these wheels like ~4K though? i don't see how you'd want to re-use tires to save money when spending so much on rims, but that's just me.
Except for wheel offset! Do you mean overall diameter? That is maintained within 1% on 265/35/R19 tires with 19x9.5 wheels.
EDIT: Actually i don't think Signature Wheel makes a 19x9.5 wheel, maybe thats why? Their fitment section for Model 3 is interesting - either 8.5" square or wider staggered set-ups, but nothing wider that is square for some reason
