8.5" front and rear? I wouldn't do it. Front tires are going to be all stretched out while rears will be all compressed on the wheel. 8.5" is not an approved width for a lot of 265s. For AX, some guys run 8.5 front and rear 245s all around, but that's not what you're talking here.
FWIW, I like your Sport Classic IIs a lot. You can probably get another set for $1K.
I like my wheels and they were around 1,200. Fit great and look good. Dont know if your into the style though. If money were no object you should want fiskes, lol. Those are the baddest ass wheels out there.
