Another noob question - what exactly would happen if they are "too loose" (if that is even the right terminology??) Are the nuts going to pop off and my tire fling off into oncoming traffic or something? Or wear down the tires (treads) faster?
Ok I should have them checked then. I've always felt that the car "glides" around the road (dry road), similar to hydroplaning on wet roads. It scares me when I actually *do* drive in rainy weather. I should probably have the goodyears (19") rotated too while I'm at it , as I'm nearing 5k miles already. Question for taking it to a local shop: is there anything in particular with "lifting" the car? I thought I saw in the manual that said the Model S on needs a special hydraulic lift so as not to lift from the battery or something like that? How is that possible when the bottom of the car is flat? Wouldn't you always have to lift from the battery pack it's the entire bottom? (want to make sure to tell my local shop any special lift requirements)

Yes, that can happen. Actually, in my case (on a full-sized van about 20 years ago) the nuts didn't pop off - but because they were loose, the wheel pulled itself off OVER the nuts when I made a turn, and went rolling across the intersection, hit a curb, bounced several feet in the air and over a fence, landed in a parking lot and continued bouncing towards the plate glass windows on the front of a Discount Tire store, screaming "Momma, I'm coming home!"
So, yeah. Make sure they're tight.

$300 for a wrench? .

- - - Updated - - -Yes, any tire shop should be able to re-torque them in five minutes. Just give them this spec: (175N.m. or 129 lb/ft)
The most obvious symptom I noticed was that the Model S would wander under full acceleration. After re-torquing them, the car is dead-on. If left unchecked, you could loose a lug nut or two, and possibly a wheel.

Same spec as the 21"... (175N.m. or 129 lb/ft)
My car has had a noticeable "wobble" on the highway, and I believe (with the help and advice on these forums) that I need an alignment. I did get my torque wrench out last night and checked the wheels. They were already torqued fairly close to spec and needed barely any noticeable amount of turn to get them cinched up. My "wobble" is still there. (not horrible or anything, but something I will ask about by my first service appt. at the latest).
i see that you have an "older" car, depending on how sensitive your butt is your tires may just be aging. sidewall is becoming softer over time. ive noticed this in all my cars and regardless of brand. some call me crazy but i can also tell if the psi in my fiat is 2-4 under what it should be. just a thought.
That quote of mine was from a while ago. The car still feels the same to me (even on the new replacement tires I put on), and so does every Tesla loaner I've had, so I'm assuming it's "just me". Tesla has done two alignments for me and aside from having a steering wheel off-center until it was fixed, no change in this sensation. It does not feel as solid and "true" as my previous Cadillac CTS did.
Zero toe provides for improved efficiency at the expense of straight line stability. Increasing the toe-in should alleviate the sensation, but it will also increase tire wear and reduce your range.
Sorry, forgot to mention that near-zero toe-in will also enhance the tramlining effect. Tires will tend to follow grooves and ruts in the road more with less toe-in.
I suspect this is exactly the cause. The "wobble" I noticed from early on is exactly like the car is "hunting" to find the ruts in the highway. My head would actually feel like it's bobbing from side to side as I drive, with the car making very tiny left/right jerks. It was very disconcerting at first, but after 3 years and experiencing it on every Tesla loaner I've had, I guess I'm used to it now. FWIW, the tire wear on my Model S is no better or worse (in terms of mileage or unevenness) than any other similar car I've had.
