Flat spot in new tires after emergency skid?

[jaymac]

So I had an emergency skidding stop yesterday with my 2 day old tires- tire smoke, screeching, the whole nine.
Now I feel what feels like a flat spot. A rythmic thud that's definitely RPM-dependant. I haven't had time to take the tire off, but I saw the skid mark later and I'd have to guesstimate it at 30 feet or so. It was a 65-0 stop, and it looks like just the left (I would assume front) tire.
Should this happen to brand new tires after 1 skid? I wouldn't think so...
I went with Mastercraft (Cooper) 255/35/18 in the front, and 275/35/18 in the back. They're inexpensive, but I did alot of research on them, and no one had any complaints on them. However, if this is truly a flat spot, I'm thinking of switching...

That's a heck of a skid. There may be a flat spot. Take them back to were you got them and let them check them out.

Put the tire with the flat spot on the back and do a burnout?

 

[jaymac]

took it back and they said there was no flat spot, however there's a warped spot on the lip of the front right, and they said a wheel and tire warp together when you hit something, so it's not as noticeable, but when you put a new tire on a warped wheel, you'll notice it more. They were a little out of balance, so they fixed that. I can still feel it, but not as bad I suppose. Oh well. Looks like I'll have to live with it...

Jeremy, really watch the tread wear all over the whole tire. I've broken radials before (resulting in flatspotting) and it felt/sounded like what you describe.



Good luck.

so JT, what should I be watching for? When you say broken radials, what exactly do you mean?

 

[HISSIN50]

The radial broke in one spot, which allowed the tire tread to bulge outward. It's like a tire hernia. After that happened, that spot's tread all wore down prematurely because it was a 'high spot'. The result was a thud thud thud sound - it felt like driving on a partial flat. I've done this twice (once was on a fairly new 200 dollar tire).
I only mention it because if you see something like this, I'd try to get the tire warrantied as defective (and since they're new, the sooner the better).

There's a member on here who's very knowledgable with tires - PM me if you want to talk to him. He can give his professional opinion about it (in case there's something he knows that we don't).

Good luck Jeremy.
