Here's mine with minimal cutting. The offroading I've done so far hasn't fully tested the limits, and I'll probably have to do some more modifying to the front. So far so good. This is with 4" susp lift, 37" MT/Rs on 17x12.5 H2 rims.

with 4 inches you need to cut your fenders for most anything other than 33x12.50, from what I understand.......... that is if you wheel very hard at all.. But I really don't know, I'm sure alot of people get away with alot bigger tires than that without cutting, its all to do with what type of wheeling you do I suppose. Sand duning and muddin is will probably let you by with less cutting than say, rockcrawling or trail riding...
Just cut the fenders and go with as big of a tire as you have gears to turn.. What gear ratio do you currently have? Do you plan on changing gears anytime soon?

You are probably going to have to get over your hesitance in regards to trimming sheetmetal if you want to run larger tires. One thing that does help a ton is to move the front diff forward between 1" and 1.5". This gains you some much needed room at the rear of the fender opening.
Here is my truck on 40's with 4-5" of lift (really old 4" lift that's a little sagged plus a 1" body lift). My front diff is moved forward 1 1/4" (redrilled the perches and spring plates) You could get offset "zero rate"s from ORD, which will gain you an inch and get the diff forward...
Here is an older pic (before cage and stuff) that shows the fender trim a little better.
I still have inner fenders, and the trim looks good with very consistant arch radii. I made a template and took my time...
Going taller just means it'll be less stable on the sidehills, and more prone to flopping or rolling over. Losing a little sheetmetal to gain a lower CoG was a no brainer for me.

That's pretty much the way to do it right if you wanna wheel.

if you have stock gear ratio, its probably 3.08 or 3.73.... If you have an auto tranny and either one of those gears you will not really want to go larger than 35. It will overheat your tranny and lug your truck way down... personally, I would stick to 33's...... or regear to something like 4.56 or 4.88 before I even thought about slapping on 36, 37, or 38 inch tires.
to find the ratio, jack the back of the truck up and spin the tire on revolution, counting how many times the drive shaft turns...... if it turns 3 times, you have 3.08....... if it turns 3 and 3/4 times, you have 3.73.......... if it turns just over 4 times, you have 4.10 (that's a good thing)...... or if you have a heavy duty truck and its your lucky day, it might turn over 4 and a half times (4.56).................
I'm betting its 3.08 if you have a K5 or K10..... so you might want to do a search on changing the ring a pinion gears in the front and rear of your axles...
