How much trimming will need to be done to clear a 265-35-22 with a 6" front drop? Pictures of what was trimmed would be great

I am running a 225/75r16 on the front of mine with a 6" static and it clears no problem... But with the offset change and extra width I am not sure what it might get into...

thats the size tire I'm running with a 4" drop and I have rub issues on the inner side of the front inner fender

so Id say your going to need to do something with your inner fender well

My front tires are .1 inch taller than that, you are going to have to tub it. And if you hit a big bump you are going to hit the a/c.

What year is your truck?

by "tub it" I assume you mean the inner fenders? I'm not worried about rubbing on the inners I've already pulled them out. I'm more concerned about the tire getting into the fender itself.

My truck is an 88

You will have to cut on the inside of the fender, not the lip.
