Slight vibration at high speed (2019 RAM Classic, brand new)

Mine does the same thing, you can see and hear the passenger seat vibrating a little bit but it stops when I go over 75 or under 65. I'll be watching your thread for responses.

This is precisely my case also... I would say nothing under 60 or over 75 MPH. This behavior is definitely related to tire balancing usually! This is why I think the mechanist at the dealer is wrong (or just don't care...)

Mine has this vibration too. From my research, it appears to be a tire balancing issue. When I got my truck in 2017, it vibrated badly from 60-70. I had the tires balanced, which they said was way off, and that certainly helped. However, the vibration still occurs most notably around 60-65, but it's way better than it was. I have the Goodyear SR-As on there and they appear to be a replacement set (tire date says 2017 and my truck is a 2015). I've heard of the GY tires causing vibrations since they aren't the best quality. I'm gonna replace with Cooper AT3 4S within the next few weeks.

Thank you very much! That's definitely something I thought about me too. The factory Goodyear SR-A have a pretty spaced tire thread (for a highway tire) and on my previous vehicle I had the Michelin Defender LTX and they were extremely quiet when the noise level of the Goodyear SR-A are pretty much like winter tires on dry and hot pavement. In fact after Google-ing it, I just found several vibration complaints regarding the SR-A on Ford and Chevy forums, since they seems to be factory tires for almost all 1500 pickup trucks of the industry...

Hi,

I drive my brand new 2019 Ram Classic for 2 weeks now and I am just back from a pretty long 700 Miles trip around Boston, MA and I noticed a slight (not huge) vibration in the truck at high speed (65-70 MPH) and it's like a general body vibration (not specific to the steering wheel I mean). I can also see the water stirring by itself in a water bottle left in the cup holder. I bring my truck back to the dealership and after a (very) short road test around the dealer, the mechanist told me that a pickup truck always vibrate as soon as there's a tiny imperfection on the road when the box is empty and because the rear end is much lighter than the front... well, this is my first pickup truck, but when I drove to Boston, I drove like 200 miles straight line on the highway 93 where the pavement is brand new (like very brand new from 4-5 days) and even on a very perfect pavement, the truck is always slightly vibrating.

I am pretty sure it can be something as stupid as a tire incorrectly balanced at the manufacture... but since the dealer's mechanist doesn't even wanted to check tire balancing as he just answer "a pickup truck always slightly vibrate" I just don't know how true it is (about the normal vibration) and if I should pay to get my wheel balanced somewhere else?

Any comments or hints are welcome!

I had my tires rebalanced yesterday and now that vibration is gone, tire tech said they were all off by 2-3 ounces. Should have done this months ago.

Son had same problem. Brought back to dealer said everything was fine. Took to tire shop and had all 4 tures balanced on Hunter Road Force machine and problem solved.
