You might consider picking up a used set of 17x8" 94-04 GT/94-01 Cobra wheels & putting the 245/45's on those. The 245/45's will physically fit on a 9", though I would use them for snow only. For year-round use, I'd look for an all-season 275/40 like the Avon you mentioned, or the KDWS as MO guy...
