9" is rather wide but the 265/70/17 p20 should fit given what people run. I have 285/70/17 on p10 rims with the LCAs pushed all the way forward. They scrub the mud flaps and do rub bits at full compression etc but this suggests you should be fine. Each car is slightly different though.
Have a look here for a rough comparison
