Shudder issue on C7 Z06
Hi. My car shudders for about the first 5-10 miles and then it goes away.
I have ascertained that a couple of the wheels are slightly buckled, but this doesn't explain the issue given it goes after driving a few miles.
Possible issues:
- flat spot on the tires
- cold tires
Any help appreciated. It didn't do this when I got it 12 months ago.
TIA Bruce

My car is a lump-fest for the first 4 or 5 miles if it's been sitting. This has been true of Supersports, Cups and Continentals. While the Contis have the best ride, they also seem to have the worst temporary flat spots.

OK. So this would seem to mirror my problem as the car has been sitting. Thanks

Interesting; temperatures? Setting how long? The PSSs on my '18 do NOT do this (I've put 2500 miles on it) and I let it set a week or two at a time, and drive it in temps down to around 45-degrees F.

I find it to be more of an issue if it's warm, particularly when you go to park the car initially. The warm tires are more pliable and then will take to the flat contact point more when parked.
It goes away once you get them warmed up again.
