I have a '98 Tahoe 2dr sport, and I'm looking to purchase some new wheels. I believe that the standard OE wheels have an offset of ET22. What range of offset can I get away with for the new wheels? For example, would an offset of -15 or an offset of 35 fit? (Just random numbers). At what point does the offset affect things like steering? I'm looking to keep the original 16" x 8" overall size also. Thanks a bunch!!
