235/75 r15 tire clearance

[SB587]

First off, thank you for letting me join. I've read a few threads, I'm happy with what I saw and I'm sure you guys will have great advise.

I bought a Baja a few days ago and I'm really loving it. Off course my first thought when buying one was bigger tires. My problem is I'm really picky about tires and of course my favorite tires are the more aggressive ones that only come in a few larger sizes.

So my question is will 235/75 r15s with 1" adapters and 1" lift clear the frame. I already know I'll have to modify the trim and wheel wells which isn't a big deal to me, my concern is the frame in the inside, back corner of the well. Since it is structural, I don't want to screw with it and ruin it's integrity. Will a 28" tire with 1 inch more offset have a problem here?

(and before anyone says it, I'm aware most 15 inch rims don't clear the calipers.)
