Vibration at 80+ mph
Hi,
Car is a 2005 C6 Z51
I have a lot of vibrations past 80mph and it gets worst at higher speed.
Tires are brand new and got the problem before changing them.
What would I need to check ?
Thanks for your help
Richard

If they’re brand new tires, all I could think of are lugnuts not correctly tightened, tires could be defective, or most likely you just need them re-balanced.
Edit: if you’ve had this problem even before changing the tires, check that your rims arnt bent. I’ve had the same problem and new gumby style rims and PS4s fixed that.

Is the vibration in the front, the back or does it seem to be the whole car? Vibration could come from all the aforementioned above but if you had the problem before the new tires and new tires didn't solve the problem, then continuing to mess with the tires isn't the answer. It could be bad wheel bearings, motor mounts, harmonic balancer, torque tube/driveshaft couplers or a combination of these things. Bad shocks will not cause a vibation and warped rotors will not typically cause a vibration until you actually hit the brakes but then the steering wheel will shake which is the giveaway that it's the rotors. I had an experience where some bad tie rods caused a vibration, so it could be a lot of different things, which is why vibrations suck. Be systematic about it and eliminate one thing at a time but try not to just throw parts at it. I hope this helps.

The vibration seems to be located at the front of the car

This might be pretty basic, but make sure the wheel stud retaining clips have been removed from all wheels. If any are in place, they will prevent the wheel from seating fully & cause vibration regardless of wheel balancing.

I had a similar thing happen to me. Everything was A OK until high speeds. Turns out that my powder coater warped my wheels during the powder coating process. Fronts were really bad and the rears were just semi bad. New set of wheels cured the problem. Although expensive, the cure was pretty simple.

@Richi Discount Tire store locations have the ability to road force balance your tires. If it is in fact a tire/wheel problem, they would be able to get you taken care of.
