1. To maximize the health of your EV battery you should not fully charge nor fully discharge it.
2. CT EPA estimates are based off HT vs AT tires
3. Tesla's EPA estimates are just a little inflated because of the way they calculate their EPA range vs the competition.
3. All vehicles to include EVs lose range in cold weather and wet roads.
4. All vehicles lose some percentage range over time.
5. All vehicles lose significant range when towing.

If all are true, what is the actual usable range to maintain the health and most range in the battery pack of the 340 mile AWD spec'd CT?

If all are true, the best case for me (will have AT tires but rarely tow) actually equals:
340 minus charge to 90% and recharge at 10% = 272 miles.
Minus 15% for AT vs HT tires = 231 miles
Minus 10% range during cold/wet driving = 208 miles.
Minus 5% battery degradation (of 340) after 10 years and 120k miles driven equals 191 miles of usable range when it's cold or wet.

Worst case (because I've seen and heard different numbers for range loss based on HT vs AT, and battery degradation after a decade.)
340 minus charge to 90% and recharge at 10% = 272 miles.
Minus 30% for AT vs HT tires equals 190 miles.
Minus 10% range during cold/wet driving = 171 miles.
Minus 10% battery degradation (of 340) after 10 years and 120k miles driven equals 137 miles of usable range in cold or wet weather.

Note this is not towing and doesn't include any range loss due to inflated EPA range estimates from Tesla.

All of your statements might be true, but do not have to be true simultaneously.

For example, if it's really cold enough to ding my range 25-30% (yes that happens up here), I'm not stopping the charge at 90%. In that 1-10 times a year situation, I'll take the extra 0.1% battery degradation when I need it.

But other than that, your premise is sound. People don't -need- 350+ miles of range unless they're towing. But they definitely -want- the results of 350+ miles of range after all the sandbags are laid on, especially in places where the charging infrastructure is still few and far between.

i have been driving model X since 2019 driven about 70000 miles , my average consumption in summer with 22 inch tire is : 352 watt hour / mile

The CT consumption still needs to be experienced but let’s assume average 450 w hour / mile , the effective range we can get 250 mile for 123 kw battery
This does not assume winter driving

True, but the tires and battery degradation will simultaneous, while the state of charge and weather will vary and can sometimes be worked around or planned for and other other times not.

Actually I want to edit this comment and say most of the time the desire to maintain a healthy battery will also be the case. So more often then not the state of charge will also limit the range, with the AT tires and battery degradation.

When I first got my M3, there were no superchargers between my home and TO so I got stuck a couple of times driving on 0%. I found the algorithm was a little off IE when charging it would show my remaining charge at my destination would be 10% and when I got there (especially in winter) it would be less than 5%. So to compensate, when at a supercharger, I would make sure that I had enough charge so that I would have 20% at my next destination and when I got there it would be around 10%.

Since the pandemic, the algorithm has greatly improved and if it says you will have 10% when you arrive you are usually with 1-2 %.

After having the car for almost 6 years and letting it go to 0% a few times and charging it to 100% when going on a longer trip (every 1-2 weeks), I see no degration in the battery (it is M3 LR 2170's) IE when charging it to 100%, it will still show 500 km or 310 miles
