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!
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).
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.

I took Jacobs XK over to Discount Tire today and tried these on. My battery was dead in the old camera and every time I tried to take a photo with my phone the blasted thing would ring and I had to answer it.
Anyway Travis took some photos and I am sure they will make it up soon after he does some research on the tires that we tested.
We tried two different size tires and I think I can even go one larger on mine since I removed the front bumper and fender, I will check when I get back from Moab.

Thanks for coming out last week Jon. It was nice to meet you in person finally.
We test fit the 17x9 0mm offset Level 8 ZX with two different tire sizes, 265/65R17 and 265/70R17. The vehicle we tested has a 2.5" lift/leveling kit and aftermarket upper control arms. It also already had some fender liner trimming done to it.
For reference. Here's the commander with stock wheels, 255/75R17 tires, and 1.5" bolt on wheel spacers.
Test Fit #1: 17x9 0mm offset Level 8 ZX wheels with P265/65R17 Falken Wild Peak AT:
Notes: This application could be good for those with stock suspension IF the vehicle owner is willing to make some modifications. The P-metric P265/65R17 tire size is approved for a 9" wide wheel. With stock suspension (no lift or leveling kit) this application may require some fender liner trimming in the front fender wells. With 2.5" lift/leveling kit little to no fender liner modifications would be needed. Please note, additional modifications may be needed for vehicle with rear Hvac.
(Test fit vehicle in pics below has a 2.5" leveling kit/lift)
Test Fit 2: 17x9 0mm offset Level 8 ZX with P265/70R17 Falken Wild Peak AT
Notes: This application is best for vehicles with a 2.5" lift or greater. Front fender liner modifications will be required to avoid rubbing. P265/70R17 is approved for this wheel. Please note, additional modifications may be needed for vehicle with rear Hvac.

Just a note for future test fitting.... there is considerably more clearance on the drivers side of vehicles equipped with rear hvac. By the looks of it, and based on the difference in clearance on my vehicle, even the 265/65/17 would probably hit the passenger side lining where the hvac lines are run.
