Well, my tires are old and dry and it is getting colder in So Cal so I experienced the front tires jumping around as if it was on pebbles or acorns as I was in reverse full turn from driveway to street. I thought it had to do something with the electric power steering and feedback only to learn about the Acorn Effect.
Thanks to this forum I avoided costly and time consuming investigation. I never experienced this in my 997....do not know if it is the tires or the 991, but at least I know it is not a problem.

Tires do play a part and can lower the temps at which the acorn noise takes effect. I hate it.

I switched to the winter tires after the acorns arrived in Seattle. I was on a road trip last week and drove through So Cal right around the time that even places as far south as LA saw the frozen water falling from the sky - I really wasn't expecting to need the winter rubber in California, but they were actually perfect for 101 and especially on my run up highway 25 from 198 to Hollister.

Temps?
Pressures?
