curiousity leads to a chain of fools

What are the odds the dealer says "RTFM" ?

Here in the Dallas area, I have 5-6 dealers within 25 miles. Sadly, I've had to use the phrase, "Do you want my business, or not" a couple times. And if the dealer cooperates, I milk it for all the info -- and time -- they will provide, then I leave and go elsewhere, just on principle. I call the dealer the farthest away for starters.

Given the tall tires and tight wheel wells on the W212, my guess is that any dealer will advise against any chains, as well. I also guess that is why it's not discussed in detail in the manuals.
Several on these forums have a Winter set of specialized Winter Tires/Wheels that they drive on during the likely snow months. Others park their MBs in the garage, and drive their "Beater" cars instead, as I do. I have 3 beater options. Your 2002 F250 4x4 sounds perfect for tearing about in the snow.

OP - FWIW
You probably have already read this but anyway
Looking in the 2016 E class manual it states on P 291 the following
Snow chains
WARNING
If snow chains are installed to the front
wheels, they may drag against the vehicle
body or chassis components. This could
cause damage to the vehicle or the tires.
There is a risk of an accident.
To avoid hazardous situations:
- never install snow chains to the front
wheels
- always install snow chains in pairs to the
rear wheels.
Further information can be found in the Digital
Operator's Manual.
I couldn't find the Digital Operators Manual

and, yes, exactly, interest in chains would be for occasional winter trips to Tahoe, Reno (where our son lives currently), etc.
with 4matic and M+S tires, we're technically OK in R1 and R2 conditions without chains, but Id want them anyways as an emergency thing.
I *am* somewhat concerned with rear-only chains on a 4matic car, as well as their impact on ESP.
That said... If you want something for that rare event (ice) you need to get through, check out cable "chains" - they work and they are very low profile, unless you go stupid on the speed, they and your 4Matic, will get you even through that... Put them on all 4, otherwise stay where you are until conditions improve...

FWIW, all the pictures I've posted have been straight from my phone (Google Pixel 3A), default settings, completely unmolested... except if I posted the circa 2014 picture of the w124 wagon in the greeeeen forest, that was shot with my DSLR.

rather, its conditions R1 and R2 that exempt AWD with M+S rated tires. Calfiornia Road Controls are...
- R1: Chains are required – snow tread tires allowed.
- R2: Chains are required on all vehicles except four wheel drive vehicles with snow tires on all four wheels.
- R3: Chains are required – all vehicles – no exceptions (almost always, highways are closed before you get R3)
3PMSF refers to this icon on the tire sidewall...
huh. for my 17" Luxury 4Matic, there's *ONE* tire in the 'grand touring all season' category at Tirerack.com which is 3PMSF rated, a Vredestein Quatrac Pro 245/45R17 XL
ditto for the 18" size on 'sports' E350's...

And it's just remarkable that the rest of the country gets through snowstorms all the time without a CALDOT inspection before proceeding.

and huh, tirerack does list the Continental DWS06 in my size, but does NOT say it is 3PMSF rated. Literally the ONLY all season they list with 3PMSF is that Vredestein.

Yes, I spent an hour or so one day watching you guys drive up this very pass, LMAO.




huh, https://www.continentaltire.com/prod...-24545zr17-99y says nothing about 3pmsf, and the side view, enlarged, I see M+S but no 3PMSF icon.








at 6:30, that triangle is the ⚠️ caution symbol on the usual warnings...

So you can get over the summit in your 4Matic with M&S Conti's, or the road is closed. But I didn't think you were asking that Q... My impression was the driveways or other roads that had actual ice on them. Studded tires, or chains are the only reliable way to safely get through that...
I hope I have helped some...
Leave the snowflake tires to someone that lives in a place where it snows all-the-time in winter
on edit: and they salt the roads to keep the ice down...

but yeah, its mostly curiosity on my part. was just kind of surprised almost none of the all season M+S rated tires for the E350 had the 3PMSF rating too.
re: pictures of your tire, you might try and find the tire model number, its like 15499710000 or something (thats a 245/45r17 99Y DWS06 current version). tires change without changing their branding, it can get downright confusing.
The Extreme Conti Contacs .... Rock IMHO, in most all conditions...

You have a 4Matic, you don’t have to worry about it. For Reno/Tahoe, they never ever require AWD with snow chains.. when it gets that bad, they close the highway. Ask me how I know.. I drove my w212 one year thru white out conditions and they closed the freeway behind me. I was literally the only one on the road..going 5mph for about 8 hours.. couldn’t see more than 15 feet in front of me.

I concur with this statement.
I have verified this to be true with the Thule chains (Konig). They will not fit on the front wheels without interference.
