Default Vibration/Shaking

Hello,

I just put on new tires(Conti Pro Sport) on my 1996 Vette. Since putting them on I have noticed quit a bit of shaking/vibration while driving over bumps. The steering column shakes. I am getting the tires rechecked (pressure/balanced) Any thoughts? Ideas?

Also would the car shake more with the targa top on and off.

Thank you,

A C4 will definitely shake more with the top off.

You're on the right track w/tire pressures and balance

Something with the tires. Some balancing machines don't center the rims correctly. Make sure of that. Could be a bad tire. The wheel shouldn't shake having the top off. Granted, with the top off the car is more flexible, but the wheel shouldn't shake.

Is it at all speeds ? Get worse the faster you go ? etc

Yeah scares me about the contis. But it was happening with the 18 yo Goodyears. I put a Gopro camera in the wheel well it really works, I found the culprit. So I had the wheel straightened but they didn't fix the wobble. New set of 17" ZR rims on the way and 2 new 285/40s. I wanted to avoid wide fronts b/c they bend easily. oh well.

Thank you,
As far as any shake to the car, i have a 96 convertible, I just took it for a drive down the interstate Sunday, umm, top down, about 80 mph, not so much as a wiggle, plenty of bumps on interstate 80 in Pennsylvania Yes the cars flex, but nothing shakes on my car, so I'm sure there's a suspension issue, or a rim issue or a tire issue.
