Winter wheels and tires just showed up in the model X store. $4500, and they are 19" (to my surprise) and wider than the model S winter wheels. Tires are 265/50r19 instead of 245/45r19.
Just sent this to my delivery specialist. Maybe some other experts here can chime in. I'm wondering if I can use my existing second set of 19" winter wheels for my model S, even though they are slightly narrower than what they are selling for the X:
I just noticed model X winter tires show up in the online store:
I was surprised to see that they are 19" wheels rather than 20". The tires are 265/50r19. My model S winter wheels are also 19" but 245/45r19 (8.0 instead of 8.5), so narrower.
So I have a question: Will I be able use my existing model S wheels and just put 245/55r19 rubber on them for the X? Those would be a little narrower than the X winter wheels (20mm), but pretty close to the same diameter. If the lug nuts are the same so I can mount the wheels, I think that would work?
Blizzaks are available in that size:
The load rating is 1,929 lbs, which seems good enough.
The way I read the numbers, 265 * 0.50 gives a sidewall height of 132.5mm for the 265/50. A 245/55 would have a sidewall height of 134.75mm, so the tires would be only 4.5mm larger in diameter. There is also at least one 245/50r19 option if that is too large for clearance.
My existing winter rubber is about worn out, so if that'll work, I'll just get 245/55r19 or 245/50r19 tires mounted now so I can swap them on if it's still snowing in Tahoe when I take delivery.
