Do you guys do anything in particular to help prevent flattening spots on the tires when it's in storage for the winter?

Mid October till mid March / early April.

Did you skip page #1?

Pump up your tires to 58 PSI. Roll the car a little in the garage every once in a while. This is a non issue. You don't need topark on anything and you certainly don't need to buy expen$ive tire cradles.

Wow, you're missing out on a lot of what I view to be still good driving time.

I don't switch to winter tires either, but mid-October is super early. Mid March is more reasonable (it's only going to finally hit the 40's around here next week)

But I've driven on countless days in October, November, even December where the roads are dry and the temps are well over 40 degrees.

Sorry, missed your post. I'm assuming by roll, put it into neutral and manually push rather than starting the car and moving? Sorry, first time having a summer car, with my motorcycle, I would just put it up on stands.

LexVan

Correct, don't start the car until spring, when you're ready for a drive.

Yes, until the salt is off the road.
I'm less concerned about driving on snow than I am about the effects of salt. We brought three cars from California to the east coast. I've seen the immediate and long-term effects of salt on the cars. It causes immediate surface corrosion and long term will rot the car out completely.
We don't replace our cars often.
I had a MINI Cooper S that sat five months in California during COVID and the tires were horribly flat-spotted. I attributed that to the fact they were cheap Hankook EVO 12 but maybe that wasn't the reason.

^ Meanwhile, there are plenty of folks who daily drive their 911's (and countless other cars) throughout the winter and report zero issues.

I am not worried about salt. I am days away from getting this car out of the garage to start driving it. I can't take it any longer. It may still snow and we may still get salt, but I just need some 40+ F days and we get those in March around here. I'm good and ready to roll very soon!!

I just checked the sidewalls on the tires, Goodyear Eagle F1 Asymmetric.
Max tire pressure is 50 psi.
Tire pressure sticker on the door jamb says recommend PSI 36 front/45 rear.
I don't think 5 PSI is going to make much difference.
Maybe I'll roll the car back and forth a few iinches.

LexVan

That's irrelevant to storage tire pressures. The delta is 13 PSI (58-45) and most here don't run 45 and the delta is greater. More like 20-22 PSI.

PCA has a video titled "Winter is Coming" where they do recommend to not go over the sidewall Max Pressure I believe. And there is also a video dedicated to tires (with two Michelin reps) that I think says the same. That said, it appears the manual allows you to go 58PSI if you want, so 58psi is probably safe.

In the PCA videos they also mention that in extreme cold (in the teens and below (Fahrenheit) I think) to not even move the car as summer tires are brittle at that point and you can damage them.

Someone mentioned above about putting the car on lifts... don't do that either... the 911 is not an RV. EDIT: Porsche says not to raise the car because the suspension can rust where you don't want it to. In The tech tactics live video from PCA, Michelin says that for long term storage (not winter, but several seasons) that getting most of the weight off of the tire is recommended and that Michelin deviates from the Porsche recommendation in that case.

You should be selecting comfort pressure on your PCM which is 30 front and 32 rear. Trust me on a porsche 911 you should not be running anywhere close to 36/45 for any kind of decent ride.
