Shaking steering wheel at 70

[72nismo]

miles an hour?Just wondering what I need to look in to see why it does that. I do have 20" wheels on my G35. I bought the wheels with used tires and i just put them on. Ive had them on for about 3 months and now I feel the shaking. Its a light shake.

Could be the tires out of balance or a belt flipped around. If you've hit any big potholes the rims could be slightly warped.

Take it to a tire place.

Ok I'll do that. Also would taking the air filter off and not replacing it would it affect the performance of the car?? Im going to replace I just haven't had time.

Yes. Don't do that, especially on a new car that you like.

It can allow junk to get into the motor. I would highly recommend getting a filter put in asap.

With dubs , old used tires and no air filter, you are well on your way to some serious abuse of your car.
