V2 Wheel Clicking

I also seem to have some clicking noticeable during low-speed maneuvering when the steering is at full-lock. Is that what you're describing? Any one else have that?

I searched the forums and didn't see anything else obvious.

Welcome to the site / forum, and sorry to hear that you are also having the wheel clicking issue. And yes, it seems that quite a few people have that issue with the wheels, and very few cases have been resolved. There are at least a few threads on this subject.

PS2's are not direction at all, they are asymetrical meaning there is an outside and inside.... How could they have a specific inner and outter and be directional??

Simple, have a specific inner and outer, and direction of rotation .

Each tire in our case would be unique, and non interchangeable.

I have seen directional tires that were left only or right only. PITA to mount and balance!

I haven't had a clicking V2 yet so I don't know what to think of it even though I have heard of a few.

Rotating the tires from side to side is an exercise in futility. There is no benefit and GM specifically says

Important: The 2007-2009 Cadillac SRX Sport with RPO R1T is equipped with 20" wheels. The front and rear tire/wheel assemblies are the same size. Customers with this vehicle are able to rotate their tires.

The above listed vehicles are manufactured with tire/wheel assemblies that are different from front to rear. In this case, the tires should not be rotated.

If a customer requests to have the tires rotated during normal maintenance, explain to them that the tire/wheel assemblies of their vehicle were designed to be different sizes to enhance the vehicle's handling performance.

Important: Changing the tire/wheel sizes or rotating the tires may affect the vehicle's handling and ride characteristics. GM DOES NOT recommend changing the OEM tires or wheels.

While I would be happy to do it if you were set on it, I would not recommend it as maintenace.

Thanks for the reply. Clearly my forum navigation and searching skills leave something to be desired.

I'm not (yet) especially broken up about the clicking. This is my first American car (long-time German car bigot) and so far it's been a delight. Some teething issues on a v1.0 car are to be expected.

I'll schedule a service visit and report back.

At about 2500 miles my CTS-V developed the wheel clicking issue when the wheels are turned to the extreme position and the car is manuvered slowly. However, there is no clicking in any other case case. While is is somewhat annoying, it is not really (IMO) a big problem, and I probably will not make a special trip to the dealer for the problem. I will ask about it if I need to be there for other reasons.

Regarding the Michelin Pilot Sport PS2 tires supplied on the 2009 CTS-V, they are definitely not directional. Anyone who believes otherwise is kidding themselves. They do have an inside and an outside (clearly marked on the tire) and, as I pointed out in an earlier post to this thread, the "Outside" designation has nothing to do with directionality. Different size rims on the front and back (due to different tire widths) prohibit front-to-back rotation. Side-to-side swapping, while technically feasible, is not recommended for this car.

Not sure why you say side-to-side swap is futile, the quote you reference only refers to front-to-back rotation. Did I miss where it says side-to-side is also not advisable?

good question, I have found that reversing the direction of rotation is often more effective than front to rear rotation in preventing or fixing noise/uneven wear anyway ( both is best if possible)

somewhere around here there was a similar comment from a tire company dude.

[ewill3rd]

Sorry that was a different document than I thought.... Try this one...

Tire Rotation
Important: Tire rotation is not recommended if your vehicle is equipped with different size tires front to rear. Refer to the tire placard on the vehicle to determine OE tire sizes.

If the vehicle is equipped with the same size tire front to rear, rotate the tires and wheels at frequent intervals to equalize wear. In addition to scheduled rotation, rotate the tire and wheel whenever uneven tire wear is noticed.

Due to dissimilar front and rear tire sizes, the tire and wheel assemblies cannot be rotated.

Yes, I see a similar note in the owners manual on page 5-80:
"Tire Inspection and Rotation
Inspect tires regularly for signs of wear or damage.
Also inspect the spare tire, if the vehicle has one.
For more information on tire inspection, see When It
Is Time for New Tires on page 5-81.
Tire rotation is not recommended if the vehicle
has 255/40R19 size tires on the front wheels and
285/35R19 size tires on the rear wheels.
Different tire sizes should not be rotated front to
rear. Each tire and wheel should only be used
in its original front or rear position."

I have been doing an internet search on side-to-side rotation and found this forum thread on Tire Rotation Pattern Theory particularly interesting.

Sorry OP for the tangent.

We need to relax with the clicking noise. The car is very stiff in order for the vehicle to have superior handling and weigh 4200 lb. I have heard my uncle's ferrari click when pulling out of his driveway. That is the name of the game when you are looking for performance out of your vehicle and in order to get that performance there are racing parts incorporated into you luxury car. If you don't want your car to have a slight click noise buy the regular cts that has a softer suspension.

Welcome to the forum / site. I feel that if that was the case then most or all CTS-V's would click. Sorry, but if GM can make most of their or almost all of their CTS-V's clickless, hey, that's sort of like chickless, then something is wrong somewhere. With the Ferrari clicking, that's probably the motor running.
We are probably looking statistically at a very few or a miniscule sample size.

[aburd]

had the tsb done on mine and the clicking is gone for now. 5500 miles
