don't know about a physical interference issue with that size, but the speedometer will be thrown off... the bigger wheel diameter means the wheel will turn slower and the speedometer will therefore read lower than you are actually travelling.

Although the effect will be minimal here, the larger overall tire diameter will negatively effect your braking and accerlation compared to the normal tire size.
