I just picked up a set of used S-Lites on craigslist and they came with a set of run-flats. They make a loud squeaking/rubbing sound from 1-25mph then the sound goes away. WFT is it? They are regular 205/45/17, so there's no way anything's rubbing. I swapped the rims in my garage, so Im wondering if I did something wrong. They all spin in a symmetrical manor, no wobbles.

I had winter run-flats on my X-Lites, and they never made this noise. Is this why people always complain about run-flats being loud?
