For winter in places where it gets cold you will probably really want to get level 2 charging at home. Even if it's just a lowly 16 amp 240v evse setup.
A 16 amp 240v evse will charge nearly 4 times faster than 12 amp 120v trickle charging.
And the level 2 will let you preheat from the grid, which can make a big difference.

The snow tires are probably responsible for about 1/3 of the range loss, with the rest being from using heat. As noted above you should consider inflating them (and the Summer tires) above the low 36psi on the door sticker. 40psi is a good compromise between Winter traction and rolling efficiency.

Re: Weather reduction on range

Well first off, I did state which car I had in the opening of my message. It's a Leaf forum and I said 2017 S 30 KWH! All good Leftie, I used to be very busy on forums so I can understand the annoyance of not knowing basic stuff when questions are posed.

Anyways, lot of good advice, lot more replies then I had anticipated. I knew the wheel/tire combo would be a bit of a burden. They're at 36 psi but if I can bump them up to 42ish then I absolutely will. They came as a set privately and look excellent so my inner car guy couldn't resist. I was unaware that the S models had different heating systems and I did a good amount of research on Leafs before I jumped on it. Though I couldn't find much negative info besides the rapid gate stuff. Oh well. I do have heated seats but not wheel. I also am mainly confused as I've used the heater a lot without having so much loss in range but perhaps it's more the tires then the heater. Or the heater working harder due to the colder outside temp.
I am not able to replenish the 65% loss during the night as the level one just barely gets me 50% and that's assuming I get home at a reasonable time, which I usually do. I also only have the level one charger and am living in a big arse 5th wheel[because screw rent prices]which doesn't have an extra 30 amp outlet anyways. I may be getting one but I'll need the L2 charger cable as well which I may not be able to get until after winter.
I was fore-warned about this issue cropping up in the cold so like I said before, I'm not too concerned as long as the issues going on are normal and expected for my situation[tires/wheels/S model heater etc].
Lastly I do have the morning pre-heat enabled for about 5 minutes before I get up. So nice! Though I'm sure with a L1 charger it'll kill 1% or so - ah well! Thanks again for the help fellas! Any more tips are certainly welcome. I also have a teeny deposit on a 2019 or 2020 Leaf Plus. So I should be able to get into one of those in.... 6ish months

In another conversation, you disagreed that snow tires are not great for EVs. Yes, snow tire lower your range and should really not be used if you can help it...

Snow tires are great for EVs in Winter - they help keep them on the road. Snow tires also can (but don't always) reduce range by varying degrees. It isn't a perfect world. I wouldn't want to crash my Leaf on a slippery road because I'd hoped for a few more miles of range...

My apologies for failing to see that - I must have been tired. If you have heated seats, then you should also have the heated steering wheel! Look for a button with an icon showing a steering wheel radiating heat, in the group of buttons on the far left of the dashboard, near the door. I'll shortly link my Tips & Tricks post for more useful info on driving a Gen...1.75?...Leaf.

I don't think the S has the heated steering wheel. At least this one doesn't.

Welcome--I drive an S-30 as well.

One thing that kind of surprised/impressed me is that a trip home last Spring through a few inches of fresh, untracked slush didn't use as much energy as I thought it would. A theory is that in slippery winter conditions, you partially exchange air resistance for snow resistance and the overall loss isn't as large.

You can also experiment with intermittent heat use. I saw a video explaining how to set the system to recirc when off, and switch to fresh air when on. Then the system can be turned on and off, and cold air won't come in the vents when off. I usually bundle up, with snowpants, gloves, and wool socks, use the heated seats, and use the heater on the first fan speed, as needed.

On the Prius I used to drive, the economy difference between winter tires and all-seasons wasn't significant. There are also some all-season tires that have very strong winter performance, and some that are quite poor. I use the survey results from Tirerack to select tires. Some grand touring tires are strong winter performers: https://www.tirerack.com/tires/surveyre ... ?type=GTAS

That will depend on where you are driving. If you are driving at 60 km/h where you would normally drive at 100 km/h, aerodynamic drag will be reduced significantly. If you have slowed down because of smooth ice and not soft snow or slush, you might even come out ahead. If you are driving at 30 km/h where you would normally drive at 50 km/h, the aerodynamic advantage is minimal and you will use significantly more energy if you are plowing through soft snow or slush. There is also the effect of climate control being a roughly constant draw, which makes more of a difference when a 20 km city drive takes 45 minutes instead of half an hour than when a 20 km highway drive takes 20 minutes instead of 12.

Yea definitely doin't have a heated steering wheel. I'll survive though haha. Thanks a lot for all the tips and that link was a nice rundown. The fastest speed on the route I take to work and back is 80 so at most I'm doing 85. I know to reduce speed a bit though, I learnt that on my first road trip to my parents. I did inflate the tires. They actually went from about 34 down to 30[I guess due to the cold temp and sitting?], so I pumped them all up to 46. That alone has absolutely made a difference. Not huge - but I'll take it. Looks like the rest is as stated above to manage my heating usage through fresh air and recirc mode when needed.
Thanks again!

Your 5th wheel most likely connect to a Nema 14-50 plug. Depending where your trailer is setup (campground, friends field, etc.) do you have access to 220-240V?

If you do have a decent supply, I would buy a dumb level 2 charger like a Duosida or similar. When you get home unplug the trailer (run on battery) and plug the car in for a couple of hours, this will do the bulk of the charging. Then plug the trailer in and use your level 1 charger to top up over night.

Even better would be to make a plug splitter so you can run both at the same time, the 5er will only have a significant draw when you are running the air conditioning or if you cook with electric.
