Intermittent Wheel Pulsing at highway speed

[01vette]

Hey Guys,

2001 Vette 68k

I have a pulsing feeling at highway speed that is intermittent. It will last for 10 to 15 miles and then go away. Seem to do it after the car has set overnight.

I don't necessarily feel the pulse in the steering wheel. But, I differently feel it while braking. Up until the time it stops completely.

I was reading on here about the wheels not being properly torqued and warped rotors and that may be it. However, I have not experienced wrapped rotor that improve while driving.

Any ideas?

Sort of sounds like tire flat spotting? Have not seen that in tire technology for a long time. Not saying it is.

Tires have less than 5K on them and never been abused.
