    I noticed this the other day...it starts around 70 and stops just after 80 or so. Nothing too bad, but very noticeable...for me.

    I had my radiator replaced..they had to remove the whole front end to do it. And I had the passenger side rear wheel replaced (just the wheel, not the tire). So the tire was taken off the old and added to the new. Not sure if either of those could have caused this, but it only started happening after the work was done.

    I have to go back to the dealer for another item in a week or so, so I'll ask them to check it out then...but has anyone else experienced this or dealt with it? Wondering what it could be.

    It sounds like they didn't balance that tire/wheel properly when they replaced it. Several people (myself included) had a vibration from the factory on their chargers in the 70-80mph range. I haven't had mine fixed yet, but I'm sure it's a tire/wheel balance issue. Others have had theirs rebalanced and the problem went away.

    The wheels/tires need road force balancing

    Feel the same around 75mph in my Charger. Never had any front end work performed. Will have them rebalance when it goes in for something else down the road.

    I've had Pirelli summer tires on from day one and it's been flawless from 0-162. This is only since they swapped radiator and wheel. Shouldn't be JUST the tires...from all the responses I'm confident it's balancing.

    I share your confidence - mine came to me like that originally, but the symptom/speed are exactly the same; hopefully easy.

    I missed the "162" - were you on a track? Couldn't have been on 611 - even at 3 AM! PA Turnpike? A really long driveway? (Or is that a secret. ;) ).

    DrBuick, where did you get the black weights. Getting ready to put my DR's on the rear this weekend.

    My buddy stopped to see me the other day and he was complaining his Hellcat Charger had a shimmy around 75 to 80.
