I recently had installed Michelin 235/60r/18 Defenders 2 on my 2021 NX. The ride feels a lot smoother compared to the OEM Yokohamas 225/60r/18 it brought from the factory. Has anyone else tried this?

I know they’re a little wider and taller than the OEM sized ones, but not by much.

 

I have been wanting to do the same thing and noticed your post today. From what I can tell there's not much difference. Diameter goes from 28.6" to 29.1".
width 8.9" to 9.3" and the Speedometer reads 60 mph you're really going 61 mph. Not much difference. I believe I'm going to do the same thing. Thanks for your post.
