How do all season tires affect the ride comfort of the EQS that is notoriously good with the summer tires?
I'm talking about the OEM tires that come with EQS not some fancy stuff.
Also I'm talking about the 20" wheels. It is known that ride comfort goes down with the larger wheels, albeit they are sportier and look nice.

EQS comes with two OEM choices of tires

a) summer tires optimized for longest range
b) all season tires

MB advises that all season tires reduce the range by about 6%.
The question is how do all season tires affect the ride comfort.

Thanks

I see your quote and raise you…

My ‘22 450 offered only summer tires with 20” wheels.

For our oftentimes snowy Ohio River valley winters, regardless of other aspects, I want all-season tires.

First hand experience here. Summer tires provide great comfort ride. On the flip side they are horrible on snow. Car gets stuck even on light snow when most of the other traffic moves. Don't dare going anywhere snowy with the summer tires. You'll get stuck guaranteed.

The performance and comfort depends on specific tires eg there are different A/S tires. My MB service told me to switch from 21" Conti Summer to A/S for comfort. I got 21" Michelin Pilot UHP A/S 4 T0 Tesla OEM tires as only available A/S tires. They are more comfortable and less sticky then summer tires, but not as comfortable and sticky as winter tires though the performance is closer to summer tires...Winter oriented All Weather A/S with 3PMSF symbol (3 peak mountain and snowflake) are more comfortable than UHP summer oriented tires, but you loose the dry/wet performance for gaining snow performance. Here is tire rack test for different Michelin tires:

Summer tires are stickier than all seasons (better grip) in dry conditions. Better grip = more control. Better grip also = less mileage due to that better control. Michelin A/S T0 improved the gas mileage a little compared to Conti summers, but I think the weather temps has more impact esp on ev vehicles. You can check range discussions with specific tires on Tesla forums as Tesla cars are longer on the roads and have more participation on their forums. For example comparison of Michelin A/S tires:

Differences between summer/AS tires vis-a-vis range, comfort, etc, don’t interested me one iota.

My only concern is coping more safely with winter weather.

And you have the right to that opinion, however it does not address the question asked by the OP. To that effect, my experience is with Michelin PS4S and Michelin PSAS4. The PS4S are smoother and quieter, in my opinion. The PSAS4 ride a little rougher, noiser, but last a little longer and have better grip in cold conditions. I cannot address snow......and hope I never will be able to address that!

If you want safety in winter, you can get winter tires with a new rim set. I did it after 26 years of driving with A/S's in midwest and NE. I highly recommend the Michelin Alpin 4 or 5 UHP tires. They are still performance based winter tires and beats some of the A/S tires eg better than Vredestein A/S in dry/wet/snow... Cross Climate 2 AW is closest to Alpine winter tires, but they lag in wet/snow performance. All it depends on your priorities... NYC temps hit 40's as of last week after 86F weather and got the leftover storm rain this weekend, so the summer tires have a very short season where I live with coastal flooding and freezing at night for 3 seasons...

The F1 summer tires are syoerbly comfortable without getting squishy.

20 inch all seasons were added for the 2023 model year (and maybe the last few months of 2022 production) and as far as I'm aware they are not runflat tires
