currently have the stock 265x65x18 tires on now. Can I go 275x65x18 or 275x75x18 without having to do any mods? Has anyone ran this size tire on a 2014 truck? I was going to get a new set of BFG KO2 pretty soon.

Was thinking about leveling and going 285 but I think I will wait til the warranty runs out before I start adding stuff to the truck. Don't really want to void the warranty or have to battle the dealership of stupid stuff if I don't have to so 275 with no mods????

Will they work or should I stay with the 265s???

You should be fine with no mods to go with 275/70R/18 BFG AT KO2.
I just put the same tires on my 2012, but I did level the truck at the same time. 275 is only 10mm wider than stock. You could also add 1 or 2 turns to torsion bars for clearance if it rubs the valance. Your clearance to the ball joint should be fine.

What do you guys think of the Ko2??? Pretty quiet? Hows the initial wear?

Anyone else with first hand knowledge of 275s on a newer truck? I really don't want to do anything to the suspension if I don't have to and if I order the 275s in either 65 or 70 profile I am stuck with them. This is for a 18" stock rim.

I also have the same size tire on xd hoss +18mm offset wheels on my 06. No leveling kit. I rub a little bit at full lock in reverse but not bad. Torsion bars aren't cranked either

They seem a little bit louder than the old design, but not bad. Only have a couple hundred miles on them so not sure about wear yet
