My set should be here in the next week or so. The more I see these wheels, the more the look grows on me. They look...purposeful.

 

I do have SPASM, and thank you on the tint compliment. I would’ve never put a tint on the car myself, but the dealership decided to do that on their own and it was already on the car when I saw it in the showroom. So, free tint for me!

And as far as TireRack and the PA5’s go, the 295 width 21” n-rated PA5’s fit just fine on the stock 11.5” width rear wheels that came with my 992 4S. Both TireRack and your dealership my try to tell you otherwise, but this setup works just fine.

 

PASM is noteworthy for providing a rougher ride. If you dont plan on tracking the car a lot, pass on PASM. Also front lift is over rated.

 

Depends on where you live. My 992 4S is my first Porsche with FAL and I plan to get it on every 911 from now on. My 991.1 turbo cab. has SPASM and no FAL and it basically acts as a snowplow on my neighborhood streets after a big snowfall.

 

What winter/all-season tires are you planning to use for your 992 Turbo S and from what source(s)?

 

The Porsche winter set for the 992 includes Michelin PA5s. The rear tires are 295/30/21 and the wheel is 11”. This tire will also fit an 11.5 wheel or the stock factory rear wheel. I plan to mount these tires on my stock wheels and have purchased a new set of wheels for my summer tires.

The ones I got have the Conti Winter Contact TS 860s

The tire storage covers did not come with these, those are pretty cheap extra that I bought, as well as the tire caddy they are sitting on...

 

Interesting info for folks on this thread. I talked to my local dealer about a 4x19 or 4x20 setup. You simply make the tires larger to match the OEM rotational diameter. Simple -1 setup math.

Porsche says that a square setup (even WITH proper rotational diameters) will ABSOLUTELY cause drivetrain damage and Porsche will NOT warranty any work needed because of such setup. In other words you MUST run a 19/20 or 20/21 setup on the 992. No exceptions.

Has anyone ever heard this before? I think its total BS. There is NO difference between a wheel and tire combo with the same rotational diameter. Its called +1 or -1 and car companies (including Porsche) have been doing it on cars for as long as there were cars. Porsche themselves do it when they offer a 19/20 setup on a car that came OEM with 20/21s.

 

Yep, sounds like BS. Is this your local dealer saying this rather than PCNA? The standard rule of thumb is that if rotational circumference isn't off from original by >3% you're OK. If it's the dealer "officially" taking this line, I'd seriously consider getting my car serviced elsewhere if that's an option.

Any time I do non-OE wheels/tires, in addition to rotational diameters I try and ensure offsets are as close to OE wheel specs as possible, but even Porsche is messing with these on the 992: the front offset for the RS Spyder, Carrera Classic and Carrera Exclusive wheels changed from ET53 for 2020 to ET50 for 2021. This is pretty solid evidence from Porsche that minor changes to tire/wheel setups won't grenade your drivetrain.

 

I think perhaps he is mistaken. I asked him to confirm with Porsche directly.

Yeah I can see offset being an issue with things like the blind spot and lane change alter systems and I have seen this with other cars I own.

 

Anyone use HRE flow forms as the basis for their winter set? Any pics?

HRE Flowform

Thinking FF11s in Bronze on my Agate.

Thanks

 

I found this on the Michelin web site. When I click the buy button it says it is not available in my area....

If you've got a RWD 911, it won't cause any drivetrain damage, but if you screw up the circumferences badly enough, you may get some interesting traction/stability control faults.
With an AWD 911 992, if you develop problems, you're likely going to get challenged on any warranty claims. It's trivial for Porsche to detect wheel changes via the TPMS sensor IDs. If you have a Carrera 4/4S, don't go cheap -- get proper staggered wheel sizes. An AWD drivetrain with staggered diameters is not the common bear. As far as I am aware, the Aventador SV/SVJ and the 992 are basically the only two AWD cars offered with staggered diameters.Of course, I am not counting cars that use electric for AWD (NSX, etc).

 

detansinn - I agree with you. The setup I am talking about is within a 0.5% diameter difference which is the same range as when you swap from a 20/21 setup to a 19/20 setup for winter. Its just simple math here. If Porsche will allow a 20 to 19 change for winter there is NO difference in a 21 to 19 change. Again as long as your setup is within the proper overall diameter. This means you could run 20s all around (like the person does above in this thread) or 19s all around which is what I am looking into.

And this is NOT about "going cheap". This is about an extra inch of sidewall for our poopty roads here in MN winters!

The Huracan has a staggered setup as well. All these are products from the same VAG family!

 

Just ordered a Winter Tire and Wheel Package from SuncoastParts.com.. The 19/20" Winter Wheel Package comes in at $4,455.00 with center caps. This is way less than quoted from a Porsche Dealership. It may not be as pretty as the 20/21" wheel choices, but if you ever have driven the New Jersey Turn Pike in Winter, you would want all the rubber you can get. The wheels are so ugly, I don't care if they get scuffed .
