Do I need to cut going to 285?

hey guys, just have a question, running 265/70/17 Do I have to cut or trim anything if I go to 285/70/17 because I cannot for warranty purposes. I am looking at Mickey thompsons MTZs (I have an excellent deal) I know they are bigger...any suggestions to get a bigger tire without doing so?

 

you gotta trim a little but not much well i didnt have to trim much at stock height with stock rims.i also add 1/4 inch spacer

 

If the alignment is in spec and you have a 2.5" lift a little trimming is required and there may be some rubbing on the steel body mounts for the cab which is tolerable and only happens when the wheels is cranked over all the way. With only a leveling kit or less you may need to trim the steel back on the body mounts.

 

I am getting a 3" lift next week but was only doing for the tires, but if i cant get them on without trimming i probably will stick with 265s
