Please help with tire size and selection

[100gold]

Okay, I'm getting to the point in my build that I need to nail my tires and wheels and get them ordered. I've settled on the Cragar ss for the wheels in the cast aluminums.

I'm looking at fronts of 17x7 with 4.25 bs and rears of 17x8 with 4.5 bs.

I gotta tell ya guys, I'm not even sure this will work at this point. It's been driving me crazy! I'm about confused at this point.

Front drop specs are 3" spindles with stock springs and rear is 5" springs.

I have an inner fender on at this time. Currently, front (inner) fender lip is measuring 30" at center of wheel. Rear is at 30.25 same.

Tires at time of measurement are 235/75/15.

Open to suggestions and all help.

Here's a pic or two as she sits now.
