Et0 downside?

Long story short, trying to order a set of 18x9, it comes with choices of et20 or et0, et20 is currently 8 months while et0 is half of that wait time, anyone with ET0 in similar size have issues? my worries are the road debris destroying the paint, is that a valid concern?

 

I have a 0 offset on mine. The tires are flush with the edge of my Bushwacker flares. Without the flares, the tires would be about 1 to 1.5 inches outside the fender. Let me see if I have pics without the flares.

 

@Downytide here is a pic with flares. Keep in mind that the right rear tire sticks out a tad more than the rest on these trucks. The other 3 are flush with the flare. I can get pics tomorrow when it's not storming out.

 

Te37xt , not planning for flares and was worried about the rash, I lost the mudflaps already too in a mud pit, I guess if go that route I gotta do ppf.....

 

20 mm is more or lesa 3/4”. Divided by 2, it will be sticking out 3/8” more or each side. I went with +1 and original 175/55-20. They stick out 2”.
