I actually run the kumho ecsta pa31! So far I love everything about them, they have tons of grip and really low road noise if that's something you're concerned about.
I have a RWD LR Model 3 so my reply is based solely on this. I have never considered any other EV so I can't tell you about them.
\- I drive my son all over Ontario, Quebec, and the northern US for his sports year round. Sometimes to very rural areas. You'd be surprised where you come across charging stations.
\- You can change your habits to allow more efficiency in the winter: schedule your charging to complete around the time you plan to leave, try to make sure your battery is warm when you drive (see first point), always make sure the battery is warm when you charge, use your heated seats more than your HVAC, lower your driving speed to match the speed limit, etc.
\- my personal experience (22k KM on my car) is that you will no doubt experience some range loss in the winter. The colder it is, the worse it is. I would say on average I lost about 30% last winter but some of that is due to my heavy foot on the clear days.
\- I have put winter tires on every car I've owned in the last 25 years. So yes - I have them on my Model 3 and yes it handles like a dream in the snow.
Update: Got the tires installed today. I noticed a major drop in road noise. I was using 9yr old Kumhos, that sat in the garage most of their life. Other than that, no noticeable difference going from 225/40 to 225/45.
225/40/19 snows are what i run on the stock wheel, the Kumho Wintercraft WP72 is a killer tire for the money ($173 on simple tire)
Kuhmo Ecsta PS91 245/40/R18
Tyres: Kumho ecsta lx platinum
I swapped my OEM tires for summer tires (Kumho Ecsta PS31), they provide much more grip and are a bit quieter though since they aren't LRR (Low Rolling Resistance) I do lose about 10% on range.
I have the LX Platinums on my GLI. After 20,000+miles, they show little wear. Handling is definitely noticeably worse than the original summer tires, but not awful. Winter traction was surprisingly good.
My experience with Kuhmos is they were prone to sidewall bubbles after pot-holes or curb contact.
horrible tire. the road noise was embarrassing on this tire. i had them on my mkv rabbit when coming to a stop it sounded like my bearings were shot.
