After some digging around it seems 235/85r16 tires will clear the strut with a back space <= 3.75in, which translates into an offset of <= -6mm. Since I have stock 7Jx16 ET20 rims with +20mm offset, seems 1.5in wheel spacers will do the trick, in lieu of getting new rims. Now rubbing on the wheel well, flaps, fender etc. is a different story, but I'm willing to sculpt my truck into a modern art masterpiece lol.
