After talking to Travis a decision has finally been made. I'll be ordering wheels tomorrow. Going with a 295 front on a 10.5 rim with 7.25 BS. I measured based on the 275 and offset the tool to make up the difference. Using a 275 with a 10" width 6.5 BS is perfect. I've offset the BS to compensate for 1/2" wheel width plus an additional 1/4 for tire width/height front and rear. I think it's a safe measurement....
I lose ~1/4 steering wheel turn from the 275 so I think it's ok to drive on the street too. I'll find up shortly...
