88 944s wheels on 89 911 carrera

Does anyone know if I can install some RUF wheels designed/used on an 88 944s 17x8.5, 17x10 with 225/45/17, 255/45/17 on an 89 911 carrera 3.2? I know that spacers will be required, but even with spacers, will these work? I have heard reports of 235/45/17, 275/40/17s being used on these cars, but I'd like to find someone that has personal experience. Any help is greatly appreciated.

TIA
