I've got them installed and they look great!
The tires fit really well. The stock 9.5" rims are really the max width the 255 width tires can accommodate, and they're a little stretched on the stock rims. 8.5" is a lot more natural.
I've never heard or read about what they described. I think there would be *less* issue on 8.5" because it isn't as stretched out.
