My car was sitting for 4 months, maybe my tires have a flat spot?

Thanks for the replies.

I will check the tire wear on the inside, the tires are practically new.

Can someone explain the feather wear a bit more, the diagram wasnt too helpful, but great effort though.

The tires are 18 inch BF KDW's. I will pull it off tommorow and check for flat spots as well, but I have a feeling that would be present at all speeds.

My stocks are bald, but that will rule out any tire issues!! Thanks for the tip.

I will also check the play of the wheel, for any wheel bearing issues.

Still trying to figure this out = "Is it a woo woo or more of a woah wee woo? I've heard a wub wub that was entirely different than a fwump fwump before."

I checked my tires this morning, no sign of feathering, had another person check it who is pretty knowledge able about tires, and he said they are fine, no sign of premature wear on the inside either from camber. I run 0 Toe in the front.

This weekend I will swap out the rims for stocks to check for the noise.

TOnight i will check for excessive play on the wheel.

My friend mentioned if the bearings are serviceable, i was not sure, i have a feeling they are not.

I think it was an attempt at a joke

Ok, results of the testing.

Checked the wheel for play, none on each side in the front.
Visually inspected everything, everything looked fine.

Switched out the SSR's for the stocks. Immediately after driving, i noticed how much smoother the ride was. Im not sure if am feeling the thicker side wall, or actually my ssr's are not balanced correctly, or I might of lost a weight.

WHen the ssr's are in the front, you feel a very very slight vibration. Very minor, but its there because the stocks dont make the car do that.

Would an unbalanced tire/wheel make that woo woo noise at speed, its very faint but I can hear it, and its not there when using the stocks.

No not really, just a general vibration.

Before I get too optomistic, can unbalanced tires cause noise at 60 to 80 mph.

I am going to get them rebalanced, but I am just curious.

On another note, today while test driving, I got a ticket at a toll, we have automated tolls here in miami, using a sun pass device, i was in a crowd of 5 cars, me being 3 , and the cop pulls me over and tickets me for going 10 mph over the limit thru the toll.

What a scam.

Are you sure the tire pressures are correct???

Sounds simple, but...

All tire pressures are at 32 psi.

I hope its the balancing.
