Both the 00' and 06' Impala use high-offset wheel and 5x115 bolt pattern. If your not using a set of take-off rims from a newer Impala 17-inch aftermarket wheels for this application are quite common.
The tire size you have selected, P225/55R17 95_ is close enough on overall diameter to have only a very small impact on odometer and speedometer ratings. It is as close to perfect as one can get. Fit with a 2006 OE wheel or an aftermarket wheel with the proper high offest will be perfect. You should run your tire pressures 2 psi higher than the factory spec for the 16-inch tires though as the 17's have a slightly lower load capacity at the same pressures.
