My 2011 Chevy Cruze LT, that I've only had since May, it has a little over 80,000 miles on it. I keep hearing this ticking so I went to premium gas it seemed to improve for a while now it's back the tick tick tick tick tick and I currently have Goodyear Assurance 215 60 R16 on it and I want to know... are the tires correct ? And should I get new rims? Or what can I do to make it a better ride and stop the ticking? please and thank you in advance.

Does it only happen when moving? Could be a nail or rock in the tire, I had a rock once that ticked when I turned only, got it out with a screwdriver and all quiet again.

If the ticking happens whenever the engine is running(regardless of if vehicle is moving or not) it's most likely the evaporative emissions purge valve on the engine. They can be noisy.

Tires don't tick unless there's debris in them. Changing wheels and tires is highly unlikely necessary.

The nickname for these motors is Ecotick because the lifters make a ticking sound.

Try a bottle of seafoam in the oil before changing the oil. 200 miles or so. See if the lifters can be cleaned out.

If that don't work try mentioned up above.

Make sure your using a quality synthetic oil, a good habit to get into is to give the car a good 1-2 minutes to warm up and to cool down. This will prolong the life of the turbo bearings and the oil.

Your tires are correctly sized.
If your car is feeling bouncy, a set of struts is probably needed. They generally last about 50-100k depending on driving.

This is my (mostly) UPDATED standing click, tick and rattle list (Thanks to many people including JBlackburn, Robby, BigLee and more) :

1. Could be just the injectors

2. Could be the plastic ECOTEC cover rattling

3. Check that the spark plugs are properly torqued - similar sound, mimics loose valves - Re-gap the plugs to .028, torque to 18 ft-lbs,no anti-seize with stock type plugs, inspect the boots and insure no rips / tears or holes, lightly coat the boots with silicone / dielectirc grease, make sure the resister springs are clean and not cocked in the boots.
These are the recommended plugs from the Hesitation Gone thread:
-BKR8EIX-2668 (iridium plugs), ~$25, expect ~10-15k regaps on these, ~40-50k overall life.
-BKR7E-4644 (nickel/copper plugs), ~$8, expect 15-25K out of these plugs, with a regap or two required at 5-8k intervals on stock tune.

4. Could be a failing EVAP purge solenoid/valve or possibly a vacuum leak causing the purge valve to stay open. You can find it right above your intake manifold.
Unplug the electrical connector to the purge solenoid while it's running, and see if the noise goes away. If it does, replace the purge solenoid assembly.
Many of these tend to get very noisy with age, and since it is duty cycled by the PCM it tends to sound very similar to valve-train noise. Part number is 5573017

5. Could be a lifter tick - how's the oil - possibly try seafoam or valvemedic

6. Could be the timing chain tensioner

7. Could be a sloppy timing chain

8. Could be piston slap/wrist pin failure. Remember, piston slap would be noticeable also in neutral.

9. Pinging caused by low octane fuel, possibly try using 91 octane fuel for a few tanks.

10. Could possibly be an improperly torqued bolt on the flywheel/torque converter (noise from the trans side)

11. Might be a bad wheel bearing, I personally had this issue.

12. Possibly the knock Sensor going off or bad and it can be exacerbated by any of the above. . The knock sensor is ALWAYS listening. The ECM is constantly adjusting spark/cam timing to run as efficiently as it can, and it should pick up on audible knock/pinging and adjust it before you even hear it.

13. Maybe your AC compressor is going bad

14. Sometimes carbon on tops of pistons or valves can cause some knock. There are several "top engine cleaners" on the market to clean that off.

15. Fuel or brake lines vibrating
#PIC5853: Buzz Vibration Noise Floor Dash Area 1800-2200 Engine RPM - (Apr 22, 2013)
Subject:Buzz Vibration Noise Floor Dash Area 1800-2200 Engine RPM
Models:2013 Chevrolet Cruze
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern Some customers may comment of a buzz noise and or vibration in the dash or floor board areas, most noticeable at 1800-2200 engine rpm.
This condition may be caused by fuel line and/or brake line vibrations entering into the cabin area through the front of dash. Even though the fuel lines and/or brake lines are fully seated in their retainers, vibrations may still pass into the cabin area.
Recommendation/Instructions Use additional tape on the affected line(s) and/or add a small O-ring underneath the affected clip(s) to provide better isolation of the clip.
Further insure that the lines do not make any contact with the front of cowl that could further cause a noise or vibration.
Validate the repair by checking for noise or vibration at 1800-2200 engine RPM.

16. Missing air deflector fasteners
#PIC5874: Fluttering Rattling or Thumping Type Noise Above 45 MPH - (Jun 12, 2013)
Subject: Fluttering Rattling or Thumping Type Noise Above 45 MPH

Models: 2011 - 2014 Chevrolet Cruze
2012 -2014 Buick Verano
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

A customer may indicate there is a flutter or thumping type noise from the side or underneath the vehicle at speeds 45 mph and above.

Check the air deflectors mounted on either side under the vehicle. Make sure that all fasteners are in place and secure. Replace fasteners as needed.

If all fasteners are secure, it may be necessary to apply felt to the underbody above the the inside edge of each air deflector (between each fastener location) to eliminate this noise.

Different sound bytes to choose from:

Some of the associated error codes:

P0324: Potential causes for this code to set are:
Defective knock sensor/s
Internal engine malfunction
Ignition misfire/s
Contaminated or substandard fuel
Defective knock sensor control wiring and/or connectors
Bad PCM or a
PCM programing error
