Default Strange 'pulsing' feeling.

I notice a strange pulse when driving off after the car has sat overnight. My thought is that the pads have settled on the routers through the night. After I drive for a while it goes away. The car only has 1000kms on it.

Any ideas..

Sounds like the tires are flat spoting over night. It's commen with performance tires.

Default is this kind of like a fine vibration that you feel coming thru the pedals and floor?

cuz i've noticed that too with my 3.0. usually happens in the mornings, but its happened well afterwards once on a roadtrip.

i'm fairly certain its not unbalanced tires because its not consistent- i've 95mph smooth as silk, only to be going 75 a bit later to feel that.

the flat spotting is an interesting theory though....

Default It feels like what a broken belt feels like. Which it is not. -m-

After a few miles it goes away. The flat spotting theory makes sence to me, however the car only sits for ~8 hours, is this enought time for this to happen?

I have a friend with a WRX who says you can slightly overinflate the tires to correct this.

Dunno....

Default broken belt? have no idea what that feels like :)

the flat spotting makes sense to me to, and i've heard that before, so that's why it never really got me concerned, but it IS annoying so I'm curious if there are other possibilities.
