I put a new set of Super High Performance Tires( or so there called) on my car and when i left for work this mornig i jumped on the gas and my car shook violently from the rear end. I did a powerslide right when i got the new tires but now everytime i try to spin'em all i get is extreme vibration.
any advise before i start trying to figure out wahats wrong?

 

Vibration just when spinning?

Wheel hop, grip of the tires against the road.

I bet if you put some cheapie tires on a different set of rims, they would just spin and no wheelhop.

 

Yeah, Dale is right, I put good rubber on mine at one piont, and all my fun wheelspins and powerslides started getting hoppy and/or wrecking stuff on the car. They are actually "good" for driving like a racer, not a drifter.
Play = cheap rubber
Business = good rubber

 

If it vibrates all the time now, seems like you knocked something loose or off, maybe a wheel weight or something?
