Default 19/20 vs 20/21

I put the RS Spyder Design wheels back on the C4S after driving all winter on my 19/20 winter wheel set (Base Carrera wheels). With the 20/21 set, it's great to have the improved traction of the summer tires, but I do have to say that I prefer the minor difference in ride quality with the bigger wheels as well. Back when I switched the other way in the Fall, I didn't note any real difference in comfort. Either way you slice it, both wheel options are low profile tires and it probably comes down to the construction of the tires more than anything else.



Granted my Summer/Winter comparison between the Pirelli's and the Continentals isn't entirely an apples to apples comparison, but it's interesting that an inch doesn't make the difference that many people would expect. So, if you want to go with the bigger wheels on your Base Carrera, knock yourself out. I don't think that you have to look at it as a ride quality compromise.

Now that we're in wheel swapping season, have others noticed the same?

I've been pleasantly surprised by the 20/21 winter setup with Michelin PA5's. The ride is smoother and quieter than my 991 turbo with 20" PA4's at all corners.

Same here
I like the Alpins 4 and 5 better than the P0s

I've put over 2000 miles on my Alpin PA5s on 20/21 wheels - much better and quieter than I expected and probably better than the summer Goodyears I had originally from a noise/comfort perspective. Switching back to summer tires in the next two weeks...

Wha a difference location can make. Here I never take off winters until at least early May, and even then sometimes have to do a return to snow boots for a week or so when a late spring snowstorm rolls in. Practically, it’s 6 months on winters and 6 on summers; hence the C4 and not a C2.

It seems to me by mid April the risk of a Colorado low showing in Calgary is pretty low and even if it does, the inevitable Chinook has the snow melted in a couple of days.Do you really swap your tires back to winters for that? I’d be inclined to drive my other car for a couple of days.

How do you guys live like that? 6 Months of snow. I could not handle 2 weeks of snow and am miserable when it dips into the 30s.

No way I'd take winters off in April, and even in May a couple of snow days are normal. Not a big deal swapping tires; takes about 30 minutes when you have two sets of wheels/tires (which we have for all our cars).

Actually, I really like it (not kidding). A high-performance car with winter tires is a heckuva lot of fun on snow- and ice-covered roads, in some ways more challenging and rewarding than driving on dry pavement. Many Canadians that grew up sliding and drifting old-school sports cars with no driver's aids look forward to the white stuff.

Agree 100%. Grew up driving in Oregon...living in Texas now I really miss driving on snow!

I could do without the days where it snows more than 4". My Porsches are both going to be parked for the next couple of days thanks to it snowing on and off here for the past 24 hours. My favorite driving conditions are when it's cold and clear outside and the roads haven't had any fresh snow for a few days. AWD Porsches have so much traction that it feels like you're driving a snowmachine.

Also, this is my first car with the Front Axle Lift feature and now I won't get another 911 without it. I use it constantly when driving in my neighborhood and when pulling in and out of my driveway. I actually wish it would lift the entire car. My BMW 750 has a button that'll do that. Besides using it when driving on unplowed streets, it would make getting in and out of the car easier.

Has zero to do with driving in the snow. I was talking about living in a cold snowy climate for 6 months out of the year . . . kind of like several I know that recently left Florida for tech industry or cyber security jobs in Seattle and could not deal with the dreary weather and moved back. I am a beach, sunny, warm weather guy. Wife grew up in Siberia though and escaped to US when she was 21. She hates cold, snowy weather worse than I.

No big deal, I was just depressed for dude when he mentioned snowy weather 6 months out of the year. I just cannot imagine living that way. Wife and I are about to retire for good to Bali and Singapore for year around sun, warmth and surfing.

My SA told me that front axle lift is disabled above 28 mph- is this true?

The Configurator says it disables at 21mph, but from my experience it happens closer to 40mph. I know it hasn't disabled itself when driving around my neighborhood.
