2005 Nissan Sentra Vibration in Steering

Have you checked for a bent rim or shifted belt in a tire? Are the tires worn evenly and not chopped?

I don't think the rim is bent anywhere. But the 3 tires are evenly worn and Rear Driver side tire is word extra.
3 tires Tread depth is 8/8 and the other tire on the rear driver side is 5/5.
Will that be cause of the problem ? If so can you please suggest a solution.

Do this... rotate the tires and see if the vibration goes away in the steering. If it does, then we know it is one of the tires.

Let me know what you find.

I rotated the Tires and tried, It reduced a bit but the problem still persists. From What i understand The issue is with Tires or Rims. I will take it to a Tire shop have them inspected. Check the Rims and Tires and try to get the issue fixed. Does this sound good? One question I have here is, can I replace the problematic tire alone ? will the Variable Tread depth across the will tires will be a problem ? or I have to change all the 4 tires ?

Yes, I think that would be a good idea. As far as replacing one tire, yes you can as long as it is the same size. As far as tread wear on the other tires, there will be a very slight difference that will hurt nothing. I do have one question. When you rotated the tires and noticed a small change, does it see as if the vibration went from the steering to the seat and floor?

Let me know. And, don't let the tire shop sell you tires you don't need.

Seems one of the wheel was out of balance fixed that and the problem resolved. Thanks a lot for your guidance....

That was a simple repair. Glad you got it fixed. Let us know if you have questions in the future.
