Ahhhhhh. Damn that's more than I thought they would.

So if they fit without cutting now, prepare for growth and cut preemptively?

If 150=1.5", then as long as you have an inch clearance you have more than enough :P

LOL. That is interesting about the growth factor. Never even thought about that before. What rear do you plan on running OP?

we got my friend 95z to fit 28s without cutting, just had to have adjustable control arms to center the rear end.

Well, seeing as 1.5" is 3/4" to the radius, you are absolutely correct. 1" should give 1/4" clearance. I realize you meant this as a jab but you kinda stepped on your dick with the math. LOL.

might want to roll the inside fender lip also. i was running 11.5 26, and it squatted too much and cut right into the sidewall.

I had 28x11.5-15 QTP's and was able to recenter the axle in the wheel wells with adjustable LCA's. No trimming, at least not to 130MPH. When I switched to M/T 28x10.5-15W ET Drags (M/T shows 28.1" diameter) with tubes, they were about 1/16" from the rear bumper. Cut the bumper plastic back, and at 130MPH on a chassis dyno they were still hitting the tip of the metal behind the cut away bumper cover. Had to hammer the metal back a little bit.

Here's the rear and the front edges of the wheel well:
