I would hope that Michelin will offer it soon as a direct replacement for the 991.1 & 991.2 20" rim OEM sizes.

EDIT: I'm also going to inquire with my Porsche Tech if the minor < 4% diameter difference is with-in the 4 wheel drive system tolerance. seems it would be given tread wear, etc....

They don't make 245/35/20 so you will need to use 255.

I wonder why the OEM rear size (305/30) is the only one to get a 30K treadlife rating

Great news.

Will definitely be putting these on my car when the P-Zeros are done.

If I am going to track the car I will get a second set of tires/wheels.

Curious to see how these compare in the snow/winter to the Bridgestones.

Hmmmm, Obvious Porsche "right foot" issues.......

Add the Staggered Fitment clause and all they are warranted for is 15K miles.

Something to consider if you are looking for a year round street tire that will perform like the OEM Michelin PS4S tires on the street. Obviously not a track tire, yet they are "W" Speed rated for the Front sizes, and "Y" speed rated in the Rear. Link below.....

MICHELIN®

Pilot® Sport All Season 4

With a Longer Mileage Warranty and 25% lower cost vs. the Pilot Sport 4S tires, its something to consider if you would like to drive your 911 year round. Plus I expect the rear tires will not have the sizing issues that the Bridgestone RE980AS tires have with the 11.5" and wider rims as shown in the pictures in this thread.

It's good to have another All Season Tire Option out there to choose from.
I considered them, but I didn't want to run 255 up front.

No XL load rating is my guess

I was considering 255 for a fat tire look (cant stand the stretched look)
What's wrong with 255 on the front? Just 8.5 rim size issue?

Yeah, seems wide on that rim, plus I already run spacers in the front. I'm sure it'll work, just didn't make sense to me. Maybe next set I'll try 255 and 305

So I check with my Michelin source and was told the Pilot Sport All Season 4 in 245/35ZR20 is scheduled to launch in July 2021.

This may be my next set of tires for my 991.2 Targa GTS

One other thing I noticed - I just did a ton of highway driving earlier this week, and I found these RE980 can often make the car feel squirmy at highway speeds. The best I can describe it is that you're holding the wheel straight, but the car feels like it is subtly moving side-to-side with a "swaying" motion. I can't seem to recall ever feeling this with the P Zero's, but I also might just be paying extra attention to the "feel" of the car given that all seasons were always going to be a bit of a gamble from a handling perspective.

mnnn....I have these for 8 months or so. If anything they feel firmly planted and not as responsive as the MPSS or PZero tires. That said, they are quieter and smoother. MPG have decreased however.

I was wondering the same thing. What would be the issue if I installed the 255/35 in the front instead of 245/35 in my Carrera T. Of course, the rears would be the 305/30. I've read the reviews on these tires and they look really, really good!

Default I‘ve never experienced this

I’m super satisfied with my Bridgestones. Maybe you forgot to tighten your lug nuts. 😂
