steel rims with the "chrome look" ss hubcaps
bought 8/27/14
I first noticed it on the ride home but put 230 miles to see if it was a flat spot tire before i went to dealer when it didn't go away.
dealer confirmed they felt the vibration and stated the tires had gflat spots that needed to be worked out and chevy policy was the truck needed to have 500 miles on it before they would replace the tires. they also agreed to comp me a full tank of gas to go run the truck to reach 500 miles. I think he lied to me but he claimed they would replace all 4 tires with new ones and check the front end alignment at that time. I think he lied because from what I read they only replace one tire at a time until its decent enough to claim they no longer feel the vibration that people dsay it still has with thos dealer tires on it.
in researching I see the bridgstone dueler ht tires and the goodyear tires have many complaints about vibration issues just from buying them unrelated to the vehicle they go on so its safe to say stock tires are crap either way even if they aren't the main issue.

Webster,
The Bridgestone Dueler HT tires are ok tires and likely not your issue. We never experienced flat spots or vibration issues. Furthermore, flat spots are really a thing of the past and mostly affects bias ply tires. The newer radial design is far superior. These tires would have to sit for years to really develop a flat spot. However, as the Duelers wear the sipes are no longer useful at the edge of the tread face and they become dangerous in the rain. Hydoplane is a problem with these crap tires. I had a set on my wife's truck. It was all over the road when the tread sipes on the shoulder were worn enough to not allow water to channel off. I dropped them like a bad habit and installed a set of Cooper's. Damn fine tire. As far as the tire balance..if the "mechanic' is worth his weight he should be able to find and fix any lateral run out the tire if there is any present. Also, sometimes a tire requires to be spun 180 degrees on the wheel to help set the bead evenly and prevent run out. All of this sounds great but I suspect the tires are not the issue.
Ok, the vibration issue. GM is famous for letting their cars and trucks leave the factory without a balance on the drums and or rotors. These items do spin and require to be balanced. I spent 2 years chasing a vibration that would shake the passenger seat at 45mph. I replaced the rims and tires. I worked at Goodyear at the time and did the work myself. Therefore the balance was dead on! The vibration persisted. After many miles and baffled I narrowed it down to the right rear wheel assembly. Removal of the wheel and checking for balance found no issue. Further inspection of the drum revealed no balance weight on the drum. The drum was replaced by GM and the vibration was gone.
Try to pin point the location of the vibration. Hard to do but after many miles of you butt shaking you can pin point it.
And a final note....the GM product of mine that vibrated like 25 cent whore house bed was the last GM product that I purchased. The vehicle was a disgrace.
Sorry you got stuck with this GM problem. I can understand you frustration. I was very frustrated with mine. Don't get me started on the VW Passat I had.
