Rear Wheel Problem

[marine_2003]

When I ride or race down the street my rear tires "wobble" from left to right. When I jacked up the car and ran it it didnt do it until i shifted into 3rd then 4th. Can anyone help?

Your tires might be out of round, or a bent wheel. Take it to a tire shop and diagnose the problem.

Tighten your lugnuts.

Don't run your car when it's up on jacks.
