Is the bolt pattern on a 97 dodge ram same as 98?

Yes, the bolt pattern on a 1997 Dodge Ram is the same as a 1998 Dodge Ram, *assuming we're talking about the same model and configuration (1500, 2500, 3500, etc.)*. There weren't any significant changes to the bolt pattern between those model years. However, always double-check the specific bolt pattern (e.g., 5x150mm, 6x5.5") using your owner's manual or a reliable parts website to be absolutely sure.
