I know I'm late to the game on these, but I got them put on today and I'm impressed! The OEM Goodyear Fortitude HT went 21,000 miles and had 6/32" tread left, but in wet, it was like driving on racing slicks. Not only do these make the Z71 look better, but they are just as quiet as the GY. Now I know why they are so highly recommended everywhere online. I stayed with the stock 265/65R18 size.
