Think I can run 285s w/o a CMC

Cutting isn’t a big deal, I would rather be safe then sorry. Tearing up my tires is more expensive than a CMC

 

It provides enough. the 285/75R16 tire is just physically TOO big to fit in the wheel well, further exacerbated by aftermarket rims that push the tire out further like yours.

 

285/75/16s. 8”et-10. 3” front lift. No cab mount chop. Trimmed a lotta plastic though.

Alignment specs play a HUGE part in with what will rub where. If you push the wheels as far forward, you’ll gain a ton of clearance between the cab mount and the tire. You’ll have to trim more up front though.

Aftermarket UCAs with caster adjustment is a must to gain the clearance while keeping alignment specs within reason

Thi# truck sees a lot of average off road situations.

 

Not quite true, there are a few special cases where some brave souls have fit 305/70r16 with no more modifications than is required to fit a 285.. Granted they are not as tall but I have been pretty set on running 305/70r16 on Fn five star 16x8 -25 et and have done some extensive googling on this fitment

 

Umm, those two sizes are the same height, both are 32.8" tall.

 

Get alignment done after your bumper is installed. You should be able to increase positive caster and push the wheels forward.

My 2019 just got a hybrid bumper, 2.5” lift, and 305/70r16 with -12 offset this past weekend. Driver side was rubbing when locked in reverse and U-turn, on the cab mount. Got my alignment today and no more rubbing, no cutting. Good luck!
