I am trying to follow this, but not 100% sure I get it. Could I run these with the 255.75.17s I dont rub with my Rubi wheels and 1.25 inch spacers unless i hit a rock really weird, and I couldnt make it rub with the spacers and stock XK wheels
2007 Jeep Commander: QTII, Leather, Sunroof, remote start, OEM Skid Plates, 2 in Daystar lift, 255.75.17 BFG Mud Terrains on Moabs, 1.25 " Spidertrax wheel spacers, 4x Guard front guard and Side Guards, Optima Red Top, Robbys half inch leveling spacer, Bilstein 5150 Rear Shocks, Pinch weld mod and trimming!
Do you know the specs of the rubi wheels? Did a quick search and came up with 7.5" wide with 6.25" backspace. If that's the case, with your 1.25" wheel spacers you're basically running 7.5" wide wheels with 5" backspace... which means these wheels will stick out 1.5" further than your current setup.
Same as posted above, turn your tire to full lock and see if you have 1.5" of clearance (imagine the tire being pushed out another 1.5" perpendicular from the hub, into the firewall)
I want to just drive down to Discount Tire and try them on, but if they won't work I am screwed because they will not put my rubi back on (rubi won't fit without the spacer) with the wheel spacer and I won't be able to get home again.

Rubi wheels have 6 inches of back spacing. I was at the dealer a few weeks ago and they were selling a set and I read the offset off of the inside of the wheel. Later that day I converted it and the calculator said 6 inches.

The issue is the stock wheels are only 7.5" wide. The stock wheels have 6" backspace... so with your 1.5" spacers you're basically running 7.5" wide wheels with 4.5" backspace. These level 8 wheels that are 9" wide with 5" backspace will stick out 1" further than your current setup. Turn your wheel to full lock and see how close they get to the firewall (keep in mind if your tires are worn that'll make a significant difference).
