My truck is bone stock, suspension wise. It does sit a tad lower than stock because of that big camper shell. My total weight is 8320. I didn't weigh it before the shell, so I don't know exactly what the shell weighs.
I have the slightest rub on the upper control arm. If I'm at full lock and if I hit a bump and if I'm moving a little fast when I do it. The tires left a clean spot around 1" long. Driver's side only.
So far I'm very happy with the Bridgestones, but I only have around 1500 miles on them, if that.
Here's a shot of the rub. Sorry, there's nothing for scale.
Here's a close up of the tire on the passenger side. Yes, I know I need to paint my hubs.
