Tallest tire I can run without adding a lift or level...

[OleMissRebels]

I'm curious as to what size tire I can get away with without installing lift kit or leveling on a 2018 z71 sierra ..  don't want to have to do any cutting, etc.

 

With that being said, I still am considering doing a 2.5 RC Lift, but am having trouble finding a place locally that installs lifts.  If anyone in the Nashville area knows of a place, let me know.

 

I'm seriously looking at bfg ko2 at 275/65/20

 

Many Thanks!

No way 275/65 fits at stock height. That's a 34 inch tire. That would definitely need a 2 inch or greater leveling kit. You can probably fit a 275/60 which is a 33. The 275/60/20's are on the new 2019+ body style. Although they do have the round wheelwells.

33's will fit fine. Not sure how much bigger, if any, you could go. I have a set of polished 20" wheels and tires from a new style silverado, and they fit without rubbing. They are 275/60/20.
