I'm looking for some OEM wheels to put snow tires on. I have seen quite a few 18" RX-8 wheels for sale. From what I can gather they are the same offset and are 18x8. I saw somebody on edmunds say they were running RX-8 rims for winter wheels on their CX-9. Is their anything to be concerned about with running these wheels on a CX-9? Are the TPMS the same?
