i will have 9" of lift when these are installed so the tires should clear. it is snowing right now but soon as it stops i will check out clearance of the spindle.
my wheels now are MWK m25 i dont know what the backspace is or anything else about them, they were on the truck when i bought it
Depending on which of these you have and your spindle to tire/rim measurement, will help determine if you clear.
MKW M25
Size .......... Bolt Pattern ...... Offset ...... Backspace ...... Hub Bore
17 x 8 ....... 6X139 ................. 0 ........... 4.50" .............. 78.1
17 x 8 ....... 6X139 ................ 25 .......... 5.48" ............. 100.3
17 x 8 ....... 6X139 ................. 0 ........... 4.50" ............. 109.8
Akuza with 6" proposed backspacing to the second MWK25 is 1/2" closer to the spindle.
Akuza with 6" proposed backspacing to the 1st and 3rd MWK25 is 1.5" closer to the spindle.
Sometimes, (maybe always), the nominal rim size and offset is stamped/cast into the rear side of the wheel. So if you have an inch clearance and your rims states 17 x 8 0, or similar, you can't do it without a wheel spacer, (but almost everyone says "Don't Use A Wheel Spacer").
Also, the tire issue.
Currently you're running the 35x12.5x17 on your 8" wide MKW m25s. They're 13.2" wide on the spec sheet's measuring 10" rim, and should be roughly about 12.4" wide on your 8" rims. The 37" Kumho KL71 on your proposed rims will be an inch wider, at about 13.5". Half an inch to the inside and half an inch to the outside of the rim.
So, best case, your current rims are the second ones I listed above, and you have a hypothetical 1" of current clearance, your new backspacing will put the rim 1/2" closer to the spindle, and the tires are 1/2" wider to each side, so you're rubbing, and need a wheel spacer of maybe an inch thick, or a different rim.
Worst case, your current rims are the first or third rims I listed with 4.5" backspacing, and you only have a hypothetical 1" of current clearance. In this case you would need a 2" wheel spacer, if they make them.
If you can make these fit and don't off road it would be an interesting/different look. But these rims don't seem like they would hold up to much, even a curb.
