I just put on a new set of Dunlop SP Maxx (235/45/17 94Y), running around 35 PSI all around. When warmed up, they're great, but after the car sits for 8 hours or overnight, the first 5 miles of travel result in vibrations felt on the steering wheel at speeds of around 50-55 mph. After that, it's back to smooth again.
I'm guessing this is a result of flat-spotting and the tires need some 'exercise' to become round again. I've read about this, but this is the first set of tires that I have owned that in fact noticeably exhibits this behavior.
Have you had any tires that were succeptible to flat-spotting? Does the issue affect mainly lower profile tires? FYI, I've had some other tires in size 225/45/17 before that didn't suffer from this (Bridgestone S03, ContiSportContact2).
