21” All season tires not a good idea?

[johnschlemmer]

I live in Seattle where winters are mostly mild, but the few weeks where we have snow it’s absolutely a nightmare with summer tires. I’ve been thinking about switching to all season to not have to worry about changing them during the winter, but I’ve also read some reports that it takes a bit on performance. Are the 21” all seasons Porsche offers really that bad? How much of a hit does 0-60 take if I use them instead of summers? Would love some input, thank you!

I’m debating the same thing on 21in rims.. I’m wondering about range differences as well. From what I’ve read all season tires generally have lower rolling resistance than summer tires. Any observations?

I live in Seattle and have the 21" wheels with all season tires. I must say that I am not that big a fan of these Continental all season tires. Also, I just had a blowout from hitting a pothole left behind by the snow. I will be towing my car over to the dealer on Monday. I will be buying a dedicated 20" winter wheel set next year.

My understanding too re summer perf tires (like mine in 21”) being a lot sticker than all season - might be that the bigger tires are the real culprit (re range impact (more contact) instead of AS vs SP!

I have the 21" all seasons, but mine are Goodyear Eagle Touring. Don't know if they are any better than the continentals.

Don't forget that summer tires have significantly less tread wear and are generally not rated for use under 7 Celsius (45 Fahrenheit). I wouldn't be surprised if summers have greater rolling resistance. Yes performance is not as good with all seasons, but I don't drive that fast anyway and don't want to be constantly buying new tires.

Im in California with a car that was purchased out of state with all season contis...they suck.

I have 8/32nds on them and I couldn't take driving on em anymore - just ordered a set of NF0 Goodyears. I was over the top impressed with them on a Q7 I owned and cant get them swapped over fast enough.

The Contis are hard comparatively. And, as you push em in a corner or freeway on ramp, they complain WAY too much. Happy to share my experience in a week or so when I swap em out. Frankly though, anything would be better than the all season conti set up.

In other news, Ill have a full set of all seasons in the garage for sale with just 5K miles on them if anyone is interested.

I’m a Seattle area 2020 4S+ owner with 21’s, 19,000 miles, and the Continental all season.

I’ve found them OK for driving in the rain, hot summer use, and the occasional “Snowmaggetons” in the lowlands. Wouldn’t trust them to go skiing at the pass. I’ve replaced them all, due to 3 separate tire damage incidents. Not the most durable. Last time it took 3 months to obtain due to back stock issues.

Still a fan of all season for the Seattle area, given the rain, unless you’re a regular skier headed to the pass.

I'm in the Seattle area. Have been driving my 911 here for the past 7 years on max performance summer( which should really be considered 3-season tires here) and haven't looked back. I used to have a spare set of wheels with winter tires mounted on and swapped for the Nov-March weather, but don't do that anymore. Instead I pay attention to weather forecasts and my car thermometer - If the temps drop in the 32-40 range, I drive very carefully. If it snows, I just don't take it out. Period. If I ever get snowed-in at work, I'll just leave the car there and take a Lyft.

All Seasons are marginally better in the freezing and seriously worse in all other conditions. IMO they are the worst tires for passenger cars as they give people false confidence. Having a 4wd with all-seasons will not get you acceptable performance in freezing wet weather. They suck equally well in summer AND/OR wet weather- your stopping distances and cornering grip will not be as good as with summer tires in the warm temps.

How bad exactly? There are many references you can consult, e.g. edmunds:

Things are much the same when braking from 60 mph. The summer tire's 157-foot stop is the shortest, the snow tires come up 2nd at 181 feet and the all-season tires lag further behind in a flurry of ABS activity on the way to a distance of 215 feet, some 58 feet longer than the summer tire.

58 feet extra with all-seasons in wet conditions. That's pretty severe and can mean walking away from a crash vs being air-lifted.

For a car that you absolutely must be able to drive in freezing wet roads, you should get proper winter tires or at least Mud+Snow (M+S) if you intend to daily the car in snow/freezing temps and swap them for summer tires when the weather turns. For Seattle, I'd say use the summer tires for the 8 months March-Oct. That's what we have on our family SUV and that's the car that goes out when we get the occasional snow.

Live in Seattle and have the stock 21" Continental all-seasons. Definitely not as good as summer tires for performance, but they behave in the rain and don't turn hard, slippery, and unsafe, at 45F either.

In short, like all all-seasons, they are a compromise. I look forward to having more options to select from when it's time to replace them.

What model of Conti comes as 21" all-seasons? I ordered the combination and Im curious what I'll receive. (I'm in Portland, OR)

If you're getting Conti you're getting ProContact RX I believe. I'm not sure if it's a covid supply chain availability issue or what, but 21" all seasons in oem Taycan sizes are basically only touring type tires. I would really like to get a set of ultra high performance all seasons (Michelin Pilot Sport 4 Season or Conti ExtremeContact DWS preferably) but they are not available in the correct sizes.

What tires do you guys recommend for 22” wheels on a Taycan 4s
Front wheel 22 x 9
Rear wheel 22 x 10.5
I was thinking about going 35 series for the front because I want some extra tire for the pot holes
What do you think of these tires below, do you think it will rub?
Front: 275/35R22 or 265/35R22
Rear: 305/30R22
