Huh. That's a really interesting comment. I ran into a guy at home depot that pulled in with a Silverado with the same wheels I was looking to put on the new truck. It was a newer truck, so I asked what year it was. Late teens IIRC. But he said he put spacers on the front to try and correct that. I don't think I've ever read that, or noticed it on any of my Silverados.
The spacers were not cheap. not putting them on the back would have saved some money. To me it was, if I'm going to move the front wheels out a little, I need to do the same for the back. The idea is to be a little more sporty with the 18" 285 Toyo directionals. I'm learning to deal with several downgrades compared to my '14 LT. No steering wheel stereo volume control (sucks), no uplevel DIC. (sucks even more). It runs well, but sounds like crap.
