little help please....
....my car has started vibrating and roaring horribly! my tires are close to the wear bars but still have good tread. safe tread. when it started, just a few weeks ago, (I don't drive it much,) it wasn't too bad I thought, ok. I need new tires soon but it has gotten WAY worse and now is vibrating the whole car! my question is could it be something other than the tires? I have about 35k mile on the car. I have never had one react this violate with tires before...

rely could be the tires.. maybe a belt separated so I'd look over all the tires pretty closely.. it could also be your harmonic balancer but I would think that would a squealing noise... let see what others think..

What type of tires? Could be out of balance if vibrating.
In my experience with the C6, as the OEM GY tires get anywhere less than 1/2 thread, they really start to increase in road noise, howling, whatever you want to call it. If they are near the wear marks, I could totally see that this could be the case. It could be a broken belt as well.
If you feel vibration in the seat, it's caused by the rear wheels out of balance, and if the vibration resonates in the steering wheel, it's the front tires out of balance.
Basically, if your tires are at the wear marks, then they are in need of changing, and that in itself will likely make your issues go away.
I never leave my tires go below 3/32" because of the road trips that we take, and the dangerous aspects of a worn tire in wet weather, which is hard to avoid during 2 week trips.

We need other info to make any assessment at all.

I agree... they are low but have good rubber left. I wouldn't ask if it wasn't so violent. at first i'm like,... I need some tires soon but in just some short driving time it has gotten REALLY bad so I ask my C6 brothers for some input.

In my vehicle my original tires were just about down to the wear bar. I looked at the closely while on the car and verified that the wear was pretty uniform across the tread. I even measured tread depth across the tire just to verify an even wear.
When the tires were removed from the car I was shocked to find out how extremely worn the inside of the tires were. So I replaced them immediately.

There is a possibility of a bent wheel.
I experienced a bad vibration early in a 5000 mile road trip, so I stopped in a tire store in Tulsa,OK, and they discovered a bent front wheel causing the imbalance. They balanced it, and I was able to finish the tip OK. I replaced the wheel after I got home.
I don't know how the wheel got bent, I don't remember hitting a curb or pothole, but it was visibly bent.

Check to see if the vibration is strongest at certain engine RPMs. When the harmonic balancer on my LS2 failed, I was getting very pronounced vibrations at about 2,000 and 4,000 RPM. I had the exact same vibrations after the harmonic balancer was changed, which is how I knew its replacement was also bad.
