Anyone knows whether 235/45 R19 would be OK? As it appears Michelin is not producing 245/45 R19 winter tires. Heard that the recommended Pirelli are not so good in tough winter condition.
The narrower tires should be ok -- just make sure the specs on the tire support an 8.5" wide wheel (I am assuming you are putting them on Tesla 19" wheels). I don't know exactly what tire you are looking at, but other tires of the same size support 7.5-9" wheels so you should be fine. Note that the speedometer reading will be off slightly, as these tires would be about 27.4" rather than 27.7" (so no clearance issues) - you would see about 1% faster on the speedometer than actual speed.
Make sure the load rating is high enough for the weight of the car - the stock tires are rated for 1653lb.
BTW - please delete the duplicate thread.

The 19" Tesla wheels are 8.0Jx19 which are 8.0" wide wheels.
@AlexK - I am pretty sure they are 8.5" wide. I know the winter wheel page now says 8", but numerous other places have said they were 8.5", including people who measured and weighed them with the tires dismounted.
Blizzaks are good winter tire and come in 19"
Nokian Hakkapeliitta R2 is also one of better tire.. The new world record for fastest car on ice was achieved by Nokian Tyres, inventor of the winter tire,when test driver Janne Laitinen drove at a speed of 208.602 mph on the ice of the Gulf of Bothnia in freezing winter weather. Grip and speed like never before were ensured by the new spearhead product for the world’s leading manufacturer of winter tires.
I went with all-season tires for chicago winters. Winter tires aren't really necessary in my humble opinion. The car is quite heavy so I'm counting on these to work and wear better than winter tires
All-season = No-season. The worst tires in every season.
Heh. Not really the worst in every season! Just no good in any season.

The 19J8.0 tire size in one of the Tesla Manuals:

@AlexK - they absolutely not 8" on the front and 9" on the rear, as you rotate them around normally - they may be 8", but all four 19" wheels are the same size. I'll measure mine tonight.
I didn't unmount them, but measuring from lip-to-lip along the inside is a hair under 9". Since the wheels are measured inside the lips, it is remotely possible these are 19x8, but I am pretty sure they are 19x8.5.
Sorry about the Tesla Manual above. I didn't look at it closely. It's an old incorrect version. Here is an excerpt from the current European manual showing both front and rear at 8.0JX19:
"European manual" -- "lb.ft" torque?? Whatever happened to Nm? Isn't even GB gone metric now? (Yes, it kills the meter in the old song "Walk a km-and-a-half-and-a-bit in my shoes" sort of dead. But why walk when you can drive, eh?) Never mind.
The tirerack has Michelin 245/45R19 X-Ice Xi3 snow tires.
I just purchased the Michelin 245/45R19 X-Ice Xi3 snow tires. Though I have them here at my house, I don't have them mounted yet. Getting separate 19" Tesla brand rims in a week or so.
The tires are rated very well on TireRack.com.
Thanks for the input everybody. I haven't been able to find Michelin tires and
at the end I went for the second best option - Continental TS810S 245/45 R19 102V XL RFT.
