Does anyone have any negative feedback regarding these tires?

I have just purchased a 2006 F150 w/ the Continental ContiTrac Tires (14000 miles).

The truck has a very "hard" ride w/ some vibration. Tires have been balanced & front end has been aligned but the truck doesn't have a good ride.

 

I had those and could hardly wait till they wore out. In fact, I still had some miles left at 31,000 when I replaced them with Michelins. All the diference in the world.

 

Those were my stock tires on my 2006 rode fine no complaints

 

Have them on my wife's '05 Escape and have no complaints. However, they're still the factory tires on that vehicle, so I have nothing to compare them against......

 

They were OEM on my Expy. THey may be the worst tires I've ever owned.
