289 front/rear tire size 15"?

[OttawaFFRer]

Gentlemen.

Am I correct in thinking the largest tire fitting under a 289 are: (and what I'm considering)

Front: 245/60/15 (mickey thompson street comp st)
Rear: 275/60/15 (MT ET street ss -OR- Nitto 555R2)

Are those my biggest and best choices for a street driver with a bit of a heavy foot at time?

Thanks

Those are the sizes I used, but mine are Cooper tires. Fill the wheel well nice, and they have been fine for regular street driving.
