White-Out

Truck has a 2.5" leveling kit from AS and 275/60's and I'm wanting to do a set of 20x10's -25 offset now. Has anyone tried to run wider wheels yet, and if so, what have you come up with. I'm thinking I'm basically near stock 4wd height, so if I have to mod or remove the crash bars I'd be ok with that, but I'm not looking to trim more than that.

The issue is with the diameter of the tire. 33" height and you should be fine. Any taller and you will have rubbing issues. Might be able go as far as 34" but that's really pushing it on just a level. 275/60/20 is exactly 33" you'll be fine.

10" is a wide wheel -25 offset would be about 4" of BS and 6" or 150mm off the hub which might rub. You probably really want to make sure that it will work before purchasing.

gahhh don't do it. I had 20x10 -12 on 33x12.5 toyos and they were so heavy. I said I'd never do that combo again. Now this was on my 04 with the 5.4 so the new motors might handle it better. I also had 3.55 gears. I had no rubbing issue with that setup. however i did have rub issues with 275/65/20 and that offset barely when backing up and I have rancho ready lift leveling struts which I also dont recommend
