Some have posted that 235's will work without spacers, other's have reported rubbing (or very close) with 235's when loaded- so you may need spacers for tires wider than the stock 215's. Here are a few links to previous posts dealing with this issue:

Try a search in this forum or the Accessories forum using 'wheel spacer' - without the ' ' - I came up with 17 topics in the 2500HD/3500 HD Trucks & Drivetrain forum.
