Flat spot on tires?

[steveo9043]

Ok is it just me or does this happen to everyone else. I swear every morning when I get in the camaro it seems as if the tire(s) get a flat spot over night. After a few miles of driving and the tires warming up its gone.

Is this normal for our tires?

Try overinflating your tires to 5 lbs above door spec.... it should help abit with it or at least make the area of flat spotting smaller.

[steveo9043]

I was thinking that or nitrogen.

You own an SS right? Do you park your car outside? Remember, unless you swapped wheels/tires you have a summer tire on there. Those PZeros are not meant for <45* so that rubber is going to be hard until it warms up. Figure you park the car outside, it drops to the 20's at night and it going to "mold" itself with a flat spot as the tire cools down. Nitrogen or overfilling isn't going to help that.

[TonyNo]

Eh, overfilling should help.

Eh, overfilling should help.

You think 5 lbs more air will eliminate the flat spot? I don't, and if you fill it any more than that you'll run the risk of wearing the tires uneven down the center. You also run the risk of reducing traction (stopping power) by over-inflating because in effect you are narrowing the tire. PZeros are bad enough right now without reducing traction further.

Well, I can tell you if your tires get a vibration all the time and you need to go get them Road Force balanced.....

My car has had a vibration issue from the rear end that just kept getting more and more noticeable. I went to dealer and told them I wanted to get a road force balance job, they tell me 79.95 and I say gettr done.

Well 4 hrs later they tell me the bad news, two of my tires are bad and will not balance!

So 2 new rear tires are ordered and will be here this week.. It was warm down here though, over 50's and 60's all week...... So now no cost road force balance and 2 new tires.....

Sorry to thread jack, but I thought if you were having the problem longer than just cold weather it could be something else.

[steveo9043]

Yes the car is parked outside right now. I had a feeling it had to do with the rubber.

The vibration is only for the first few min's of driving in the morning.

Pzeros are not good in cold weather.

[TonyNo]

I did not say eliminate.

[Bubbles]

I did not say eliminate.

Nor did I

This is definitly the tire and tempurature combo.First please remember that the tire is an extreme performance summer tire made for driving above 40 degrees only.
When sitting out in cold the tire forms a flat spot that works its way out as the tire warms up. I woud suggest not driving summer tires in the winter but if you are going to have to drive on them in winter. Be extremely carefull. The Nitrogen will help with the drastic loss of pressure do to tempurature variations. But it will not stop the tire from flat spotting outside. This flat spotting should not damage tire. There is a drive on pad you can get that will reduce it but not worth it in this application.

G-Man,

Do you sell the pad? What is it, do you know how much it cost and where we couldget it if you do not sell it?
Thank you.
