IIRC, it's the nylon cords in high-speed rated tires that are often responsible for the flat-spotting effect. If you park them while they're hot and pliable, they take a set as they cool and need to be warmed up again to regain their flexibility and go back to being round.
If this car is used primarily on short, low-speed commutes, don't go higher than H-rated, or else you'll be living with a lot of flatspotting. I learned this the hard way.
If most trips include a few miles at high speed, go for the V-/W-/Z-rated tires if you want.
