C6 z06 front tires cupping

[Mitch10]

Hey guys. Took my tires off to get a new set of wheels installed. And I noticed that all around the front tire (only the one side) there are a few patches about 4”by 4” of wear. And one spot Is almost to the wires. Would this be a sign of bad shocks I take it? Or what else would y’all look at to trouble shoot/replace.
Thanks.

For sure. I will get some tomorrow as the tires are stored in the shop.

Guess that didn’t work either.. it used to, I guess I need lessons on how to post pics again

My first question... "What tire pressures are you running"? Cupping typically occurs from under inflation.

 

[kerry4]

That was my first thought too vintageracer. On motorcycle tires they will cup if under inflated.

 

[Mitch10]

32 psi or so. If it was tire pressure it should be both sides as I keep the pressure dead even.

Okay. My limited potential usefulness just ran out. I guess I am stumped too.
Sorry.

Is that a picture of one tire in two different spots or are the inside of both front tires worn on the inside/

 

[Mitch10]

Same tire. 2 different spots. As it’s like that all the way around. The first pic is just of the worst part.

From my experience that is caused by worn parts or bad alignment. Take it to a shop you trust for an estimate/opinion. I have had a shop I did not know give me bad information..

I'm leaning towards the improper balance issue.

That’s interesting. Yeah it’s looking like a balance and shocks.

If it is a balance issue , you more than likely would feel a vibration in the steering. I am more prone to believe it would be an alignment issue..

 

[SladeX]

The front tires are usually good at masking a balance issue due to being more or less independent. Especially when its just a slight imbalance. A very slight one would not be noticeable at low speeds, and only when you get to excessive speeds, would the imbalance be more prevalent as a shudder. A lopey cam or poly engine mounts and that imbalance shudder is tough to really feel for.

An alignment issue usually comes with some tracking issues. Some more drift when trying to drive straight or when doing longer sweeping turns, you find going right requires more twitch corrections than going left.
