What tires would you run with wheel well headers ?

I was running 165R15 (25.43" tall) on 15x3.5 Centerlines. They hit my Hooker Super Comp fenderwells no matter what I tried to do. I made some strategic "clearancing" on a few tubes, raised, lowered, etc. Now I picked up 155 80R15 (24.8" tall) for 15x3.5 Shelby Cal 500 aluminum slots. Waiting on lug nuts to try them out. The 14" ralley wheels with 185 75R14 (24.9" tall) didn't hit at all. I "should" be in the clear now as the new ones are the same height as the ralleys. For me, it seems like 25" or just under is the magic number, but I also clearanced some tubes already.
