RE: Bad vibes

["Duff, Ian" <iduff@charter.com>]

What brand of tires? Squarellis have a well deserved rep for flat
spotting after sitting for a while, eventually morphing into "round,
black, holds air". It could be the tire on your car develops flat spots,
which work themselves out as they warm up. New tires of the same brand
may have the same characteristics, you should change brand to ensure
this isn't the case. HTH.
