    I can't comment on the Z71, but I've got an 08 Silverado 4x4 with the stock 20's on it. No problems at all.

    Like Peter mentions the ride quality of a stiffer suspension and bigger wheels/tires would be of concern to many truck owners.
    Almost every set of 20" tires made have a lot less sidewall than any other size tires, unless your running low profile tires, this lack of sidewall equates to ride quality, low profile tires suffer from less sidewall flex than normal size tires and this makes their ride stiffer.
    This was a common knowledge issue years ago that if you went to low profile the ride quality got worse, new tire technology and softer suspensions have made this less of a problem than it used to be but the problem still exists.
    Most people arent aware of the fact that tires are a part of the suspension that determines ride quality.
