    Looks like my only option is going to be 275/70/18 and keep the stock wheels. At least It'll be a little taller!

    Thanks! That's what I'm looking for. They look really good on yours. Any fitment issues?

    There was just a slight bit of rubbing on the front mud flaps when backing up while turning sharp. I just removed the two front mud flaps via 2 screws each and problem solved. My wheels do have less offset though. Stock wheels at +60 offset are said to have zero rubbing while my aftermarket wheels are at +25 offset. You can see in the picture how close the front tires are to the front bumper and those little front mud flaps that hang fron the front bumper. That pic was taken before I removed those front flaps.

    I ran KO’s for two days and returned them to Discount Tire for Ridge Grapplers. The road noise is unbearable and the ride was horrid. Glad they are gone.

    Look at
    305/65r18. ½” more diameter and 1.2” wider (won’t be that much wider on a stock rim).

    I have the 275/70r18 and wish I did the 305’s. 2-3% of the time that I look at my truck my tires just seem too skinny. But the rest of the time I’m happy with them.

    I have zero rub with my current setup (stock trd off road suspension). No mudflap or liner adjustment. I’d expect a little of adjustment with 305’s but not much)

    I thought about 305's but theres just really not enough of a difference other than width. Wish they made a 295 in the KO2!

    Yeah. That’s why I like them with a stock suspension. Toytec makes urinal cake spacers that give you ½”-¾” lift. Might run those if the 305’s rub.

    275/70/18 no lift. It was funny though, pricing them out, this actually was one of the cheaper sizes, one or two sizes different was a pretty good price jump

    I would love this setup. I am looking at doing a Readylift 3/2 leveling kit. Would I need a body mount chop to get them to fit? Man, I wish they made a 295/70/18....

    275/70/18. Might have to bend skid plate just a tad. Took me about 10 seconds. Everything else clears perfect.

    I stayed stock 275/65/18. Didn't want to have to worry about clearance. No plans for a lift

    285/65R18, no lift.
    I bought my 2015 previously-owned in 2018 with 19,700 miles, pretty sure these have been on the truck since 2015 looking at the dates of the tires. ~33,000 miles now.
    They look tough as nails which I like, but I agree with @treihing.
    Loud road noise and stiff ride. Not a lot of traction on wet roads either.
    I bought a Sierra back in 2003 that had them also. Replaced them with Mastercrafts after they wore down. No regrets in not going back to KO2s.
    I don't off-road, but need snow-ready traction in the winter here in Michigan. Am thinking of going down to 255's in Pathfinders, Wildpeaks or Grapplers in 2021.
    Am open to comments/opinions on any of these three! Thanks!
