Changing from a 205 to a 215 is only 10mm - not much. Check the actual measurements of the tire from the manufacturer's specs. You'll be surprized how much variance there is actual size from one make to another.
A larger tire may rub (usually the front at full steering lock), will give slightly higher ride height and will minimally affect the gearing (speed will be higher than indicated).
