Just having trouble finding a definitive answer elsewhere on the forums. Are the OEM 16 and 18 inch wheels forged or cast? Just wanted to know whether sticking with oem is better than having to spend a lot on the TRD forged wheels. Also, I saw on tire rack some wheels with a good offset for me, but they are cast. Is this really bad for off roading? I was thinking about possibly going 285/75/18 and wanted 25mm offset to potentially avoid the need for spacers. Thanks
