Question, will Level 8 Mk6 wheels in a 17x 9 with -12 offset need spacers?

Looking at 35x12.5 tires or 11.5 if I can get them. Running TC UCA's as well. Not sure how to figure out the offset needs for these wheels.

Thanks in advance

 

Use this to calculate and Visualize

 

Running 16x9 -12 offset on a 315/75 without spacers. Wheel already pushes beyond stock. Fender trim and cmc are definitely gonna be necessary for 35’s

 

Got any pictures? Fender chop at the bottom? CMC and pinch weld will be done, not an issue.

 

Fender trail full wheel well

 

Trim not trail

 

Im running 285/70R17's with those exact wheels and a 2 inch spacer lift that came on the truck. They rub the cab mount at full lock in a parking lot.

 

Bought the wheels... thanks for the input!
