Max Tire Size for 18x9.5 +12 Wheels-No CMC

Here are the details of my truck. I have a 2018 Tundra with a full OME lift and the 614 coils. RCI front skid plate and coachbuilder bumper shims (installed for anticipated rubbing with new wheels).

I was pretty much dead set on ICON 18" with a +25 offset and going with 295 70 R18's on them.

However, I was looking of craigslist and came across a set of Black Rhino's Barstow 18" rims. Looking at the specs they are 12x9.5 +12 offset with 5.7" of backspacing. I've been looking but really can't find an answer on what the largest wheel I should be able to run without having to do a CMC\BMC. Any input would be appreciated.

 

Guess it will be trial by fire. Scored these on CL for $340.00

 

Any pictures of these on your truck? What tire did you end up going with??

 

Not yet, waiting till I need new tires to put them on.
