Other than a slight rubbing of the front tires if you really hold the wheel in a very tight slow turn, no issues so far, and I'm 3-1/2 years into using these AT tires. The rubbing is only when the wheel is held extremely tight to the left or right, but doesn't occur with normal turning, and even when it rubs it's a very slight rub. Cannot see any area on the tires or the interior fenders where the rubbing occurs, so I take that to mean it's rare and inconsequential.
Thanks, appreciate your feedback. The main concerns I had going with this size is that

1) the new diameter is 30" instead of 29" which is slightly over the recommend 3% limit which some say might cause issue with ABS and traction control systems

Other than the speedometer being off by couple of mph (which I don't care much about) , my other concern was recommended rim width for 255/50 is 20x8 but the stock is 20x8.5

The stock KIA wheels worked just fine with the new AT tires, but there is a 1-2 MPH speed difference, which I find manageable. I haven't noticed any difference in ABS, general braking or traction control.

Thank you, you convinced me enough to go with 255/50 !!! :)
