Realizing that it's time for tires on the '89 Westy-- I've decided that 15" rims are a must.  The question:  how much tire is too much?  I was contemplating 235/75/R15 -- anyone running the same,  and what if any changes (outside of the offset issue) have you encountered?

Pat,
They'll rub in the front when turning, unless you trim the wheel well opening and bevel the corner of the battery box. 225's might work, but I think 215's are what most guys are winding up with.
