I also have a rather loud click on some after market wheels. But, it only happens when I make a slow sharp right turn. It also happens once each time the wheel makes a full revolution. I will do more research tomorrow. Cecil............

You should periodically retorque the wheels regardless of what it says in the owners manual. That is the permanent solution.

You may be experiencing tire scrub (like a tire skid and bump), which is normal for that fat *** tire at slow speed.
we have a relatively fast pace clicking.

What's a good tool to torque the wheels with? It's 100 pounds right?

I had the same problem with my 2011 Cadillac CTS-V....dealer started out cleaning back of wheels and hubs; that worked for a while. Finally, a service bulletin came out directing the dealers to exchange the stock Brembo rotors for a 2 piece rotors; that worked for a while. Long story short...final bulletin said they should use a different type of lug nut and torque to 115 ft pounds rather than the 140 shown in the service manual. That was the last fix done to my car and seemed to fix the problem.

I'm surprised GM's studs hold up at 140 ft/lb. I hear they snap even at 100 ft/lb sometimes.

Most of the ticking heard has to do with the 'Floating Rotor' design of the brakes.

I have heard the floating rotors can make noise, I am unsure of the sound they produce, but the cleaning of the wheel temporarily eliminates this clicking sound, so I am sure they are different noises that are being made

Torque wrench, pic of old style and new style attached. 1/2" drive...Google images. correct 100lbs.

The clicking on mine is always from the rear rotors. The dealer removed and cleaned the rust from them 3 times now and it worked for a couple of weeks.

Recently I drove 4 new Z06/7's while at Spring Mountain. Each of them had the same clicking at initial take off.

I decided that I really don't want any dealer removing the wheels anymore for a temporary fix. There is too great a likelyhood that they crack a ceramic rotor and then say it was that way when I brought it in. They have been denying cracked rotor claims caused by damage.

You are not snapping a stud off with your torque wrench set on 100 pounds!

More like a wire wheel!

Several of us have had problems with defective lugs. One of mine wouldn't take 80lbs. I had 3 of mine stretch before going to ARP lugs. One of mine stretched initially, and after waiting 5-10 minutes held 100 ft/lbs just fine. Something weird is going on with the OEM lugs.

Sorry to resurrect this old thread, but my dealer just found the source of ticking in both my front tires (Z06/Z07). The ticking would happen when you turn to the right or left. It sounded like a pebble stuck in the tire.

Like the OP, the dealer did eventually remove the wheels and clean the hub and the back of the wheel. And stuck someplace in the hub on both sides was the tail end of a zip tie! (The part that you cut off after tightening the zip tie.) Apparently they zip tie something in place there when the car is built, except with mine they didn't both to remove the part they snipped off, and it got stuck in there.

Ticking gone!
