Vibration after extreme temp change

[MarkChai]

I live in Phoenix, AZ and yesterday it was well over 100 degrees, and the car was hot from a highway drive. Then a very heavy rainstorm quickly came in, dropping the temperature to 73 deg. F and flooding the streets. I was still driving at the time.

Once things let up, there was a significant vibration from more than one tire/wheel at any speed, but obviously more vibration at higher speed., even in the steering wheel.

I haven't gotten to check it out yet, but there are obviously 3 possibilities:

Tires out of balance

Wheels warped

Rotors warped

What the most likely due to a temp change like that - very hot wheels, tires and brakes suddenly going through cold water, and driving through flooded streets for an excess of 20minutes?

Thanks!

Rotors could have warped but i think you should only be feeling that when you are braking. Wheels don't tend to warp because of weather just like that.

It must have just been water on the rotors or something? Today it was back to normal, no vibrations, just my noisy Kumho Ecsta SPTs as usual. Weird.
