Bigger tires

I bought a nitto ridge grappler size 285 70 17 tires. Do I need to cut on the cab mount?? I have a 1.5 wheel spacers and a 3inch lift..

They should work fine with at setup.
I just put the same size tires on I have no rubbing except at full turn on UCA. Going to install spacers to get rid of that as soon as they come in. Stock rims.

 

Do you have stock rims?

 

I'm stepping up to stt pros 285 70 17s next week. I've smashed down the pinch weld getting a cmc on Tuesday and will trim plastic as needed. 2.5 inch lift on 17 x 8.5 4.5 back spacing -6 offset wheels.

 

This is the rims I'm gonna be putting with my tires i hope it would work because I ordered it already.
