Does anyone know what the thread size and hex size is for the lugs on the TRD/RH 18" rims for the xA?
I am trying to get wheel locks for them and I don't know this info. Thanks.

12x1.5mm
At least if you have the same Lugs as me. I'd go for Cone nuts over flat ones as well..

Thanks for the info.
One more question: Do the locks replace the lug or are they an addition?
