update turns out my alignment was out Seems odd so new but we have some nasty highways in manitoba. Since have been on 4000 km trip no cupping

 

Thought I'd update cupping started again I have now gone to bilsteins I take stock ford shocks compress takes forever to return bilsteins is like instant. Can't believe the difference and that ford has such cheap shocks. New truck next year will go straight to bilsteins. Good advise thanks

 

x2. Centramatics make the truck ride as smooth as possible and tire wear is even. Love them. I did not remove any wheel weights though.

For those that rotate often, do you do it yourself? And if so, how do you reprogram the TPMS?

 

The stock shocks are a cheap shock, but that's not the reason for the slow extension compared to the Bilstein's. The slow extension is because they are different style of shocks. The stock shocks are twin tube (like Rancho) using a low charge, the Bilstein's are a mono tube with a high gas charge.

I have only experienced tire cupping on my other truck (not a SD). Aignment had been done but the tires that cupped did have issues with balancing. That same truck has 60k miles on the current set of tires without any cupping. Suspension was untouched. One shop said it could be caused by a few different things but that once it happens to the tire it doesn't go away.
