Wow that's lot of bad tires if u ask me. (Lol)

My guess is they are all good year tires, Someone at GM should be pi$$ed with all the vibration troubles.

While my truck was at the dealer they gave me a 2014 tx edition with 500 miles as a loaner with continetal tires and it had the same vibration.. I think they don't know what the problem is so they blame the tires ... I ran the same goodyear tire on my 2008 sierra tx edition and had no problems at all. ( And why would they have my dealer shim my motor mounts with washers) A $38000 dollar truck with washers on the motor mounts...

yes it is mostly tires or the poor balancing of such. All new tires will ride much better if trued by someone that knows how to properly true a tire and high speed balance on the car/truck. A new truck here or there may have mechanical issue but most vibs in steering wheel and seat are the result of tires and balancing. All tires are out of round some and weight too. It is a matter if enough to cause a ride problem even with a good balance.

 

If I were one of the unfortunate here with the vibration problem, I would start with the tires. And not at the dealership. Then with good tires and balance and still a problem go back to the dealer. Let the dealer know about the vib problem and take their shot and then if not fixed, let them know you are going to replace the oems. This way they cannot say well it is those new Michelins....

 

Unless it comes with Michelins, to me replacing oem tires is just a mod that should be done as soon as possible. Same with shocks.

They must have got a really good deal on a train load of these lousy tires. Which in the end was a very bad deal after all. Or, there is another problem somewhere and they have no idea what.

Balancing tires properly is a neverending problem. Tires on my '09 Impala LTZ are difficult to balance for some reason and usually it takes three tries to get them balanced perfectly. I get a smooth ride for 20k miles if they are done right, so I know the tires are good. Generally the larger the tire diameter, the more difficult they are to balance properly. And cars are typically more sensitive to improperly balanced tires than trucks.

Well it has been about 200 miles since the dealer swapped the goodyears for Bridgstones and yes the wobble is gone, but I have to say this is the worst truck ever. The steering wheel is not smooth there is a constant slight vibration that is not tire related and even the smallest cracks in the road feel like you are hitting giant pot holes and the whole truck bounces. Every little thing is felt directly through the steering wheel.

 

If anyone is reading this post DO NOT BUY ONE OF THESE!!! I have had at least 10 chevy and GMC trucks and never had such an awful time driving a vehicle as this one. Can't wait to trade out of it.

I typically never buy first year redesigned vehicles, no matter what the make and model. They all seem to have some issues, some worse than others. But these vibration problems are very frustrating.

 

Have tried running slightly lower pressure in your tires to see if the ride is less harsh? I mean 2 to 4 psi less, anything beyond that may be unsafe.

Just had my 2014 Silverado Crew Cab4x4 6'6 " box 3.42 rear end to dealer for vibration but this happens at approx 30 mph at 3000 rpms under moderate to heavy acceleration coming out of a turn but they couldn't duplicate it. I also have noticed the tach surging when in 4 cyl mode at 1000-1200 rpms when going up slight incline but forgot to mention it to them. Have not noticed the vibration at 60 mph and up and I have Goodyear tires not sure which model. 3100 miles on truck but I have a topper so maybe the extra weight of that makes it not noticable. I also complained about a large hesitation when going up hill, letting off gas then trying to accelerate. The truck will do nothing to accelerate for at least a second (seems like forever) then will take off like nothing happened. Only happened twice. The dealer said it normal so the trans gears don't slam into each other. I think otherwise.

I just bought a 2014 Silverado, with the former "extended" cab setup, 5.3 l engine,18 inch wheels, Goodyear tires. I'm thinking I should have run away...when I first drove the vehicle, on the interstate, I said out loud to the salesman and my wife "it has a vibration." Thinking it was just an unbalanced tire, I went ahead and purchased the truck. Now, the dealer has force balanced all the tires, which did not solve the problem. The service manager has agreed that there is a vibration, but he and a technician drove other trucks of the same configuration under the same circumstances - about 65 to 72 mph - and they all had the same vibration. I am not happy with Chevrolet...These vehicles are advertised as being quiet and so forth...not so. I am not a happy camper. I won't be able to speak again with the dealer until next week. A poor vehicle. I will pursue my options now, with the things I've seen here.

I think your issue is "Dealer force balanced" Key word is Dealer. Take it to a reputable tire specific store and have them do it. It's apparent that GM and it's dealers either don't have the proper equipment/ training or both.

 

Either that or demand they change the tires to another brand other than Goodyear.

I don't think its the tires unless they are not balanced properly. I have been reading the thread about the vibration and possible tire issue. We have two 14 LTZ Silverado 4x4 short bed crew cabs in our house hold. Both have the 20 chrome rims with 275 55 20 Wrangler SRA tires. Neither have any type vibration at all up to 90 mph and are as quiet as a church mouse. That's as fast as I have been. One truck has 4,000 miles and the other close to 2,000 miles on it.

I would not expect a dealership to be able to properly balance a tire in 30 mins or 30 days. find a good tire shop. Then you will know: 1. it is the tires or 2. it is not the tires.

 

A good shop can tell you if it is too far out to balance. Then new tire. A really good tire shop can true a tire and high speed balance on the auto. A really good shop like this is hard to find but if you do put them on your Christmas list.

 

Again, replacing OEMs and a good balance job should be considered a mod and not play lets beat up the dealership tell they give me new tires that they cannot balance either. Good luck guys.

    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back. 
    • That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed. Why not updates as well, especially since some of those can be safety related also?
    • That's good to know, but I don't think I'll even be running them under 45 in the rear  unless it's on the sand or something but will only be for a short distance anyways!    I didn't read all the instructions in the booklet yet, but do you know let's say I set the rear psi on the placard to 45, will the warning light come on soon as it drops under 45 or is there a percentage it has to drop from the set value before the warning light is triggered?
    • That's bad.  Like, its probably destroying the stub axle the CV slides into.   Do you have a proper lift installed with differential lowering brackets?  Did you install AT4/Trail Boss factory CV axles?  
    • Hot? New Jersey? Today? I was working on my old 2000 Silverado 1500 today. Believe me, it was boiling hot today. As it has been.
