Tire Flat-spotting

[ErikB]

I've got a set of Falken Azenis ST115s on my 2002 530i Sport. While the tires are quiet and handle well they have a problem with flat-spotting when the car sits for any length of time (usually more than a couple of hours).

I live in an area where when I exit the neighborhood I pull out onto a highway that has a 50 mph speed limit. I immediately get the steering wheel shimmy between 50 and 55 mph. After I drive for a while (or go above or below that speed) it stops.

Are you guys familiar with which tires are known NOT to have that characteristic? I talked with a guy that was running Michelins (I think Pilot Sports) and he said his did the same thing (although maybe not as pronounced).

Ideas?

Never had a problem with my continentals..

I'll say i've never had a problem WITH FLATSPOTTING on my yokohamas. I've had a problem with a tire losing its bead and flinging me into an embankment however.

Never had a problem with BFG's or Sumitomos. Even after sitting for a week+.

I had that problem with Yokohama AVS ES100's...extremely soft compound, noisy, and short thread-life.
Not too bad with my current Fuzion ZRi's, but sometimes I still feel the shimmy till it warms up, which doesn't take too long, about a couple miles.
