No Jack or Lug wrench since I haven’t received the jack pads I ordered. should be able to find the nail/screw by rolling the tire forward and then plugging it with the kit. Not looking for a flat tire but if it happens I will film it.

Has anyone really used a 12V pump to fill tire?

Cool - Glad you already thought of knee protection !!! Learned from experience with a blown out sidewall a few years back and no knee protection.

Actually the correct statement is The Model 3 has no fuses that are user replaceable.
The 12V lighter socket is fused, it is a software fuse, it can be blown, ask me how I know. It will reset on it's own but is not quick about it.

Oh stop it.
You know what I meant.
no one ever wants to be wrong anymore.
There are no fuses that exist in 99% of all other cars.
Geeesshhh...
We use this pump from Canadian Tire: MotoMaster 12V Direct Drive Inflator, 3-Minute | Canadian Tire
After a few corners it gets very hot, but it is able to reach over 50psi for each tire!

I own this pump and have been using it on my last three ICE cars: Michelin 12V Deluxe Inflator | Canadian Tire
When I try it with the cigarette lighter in my TM3, it would power on but will not pump. Does anyone know why? It is a 12v pump from the product page.
Also I noticed, the PSI displayed on the pump keeps on jumping.. like its broken. For example, on one tire the TM3 screen shows 38 psi but my pump jump from 38 psi to 70 psi and back down to 58 psi. Not sure if its fighting with the TPMS or what. Just want to ask before I invest into a new pump since this was one working fine (before my TM3 purchase in June)

Either the pump is no good now or is it pushed on all the way then seated down on the valve.
TPMS is just a sensor, it can not fight the pump or cause it to display higher than the pressure that is there. I think the pump is toast.

This is what i have and end up using 3-4 times a year during season change to pump all 4 tires. Gauge on it is worthless, so i bought cheap Amazon tire gauge which gives me exact tire pressure that Tesla shows. https://www.amazon.com/gp/product/B01M1H5BZP

I bought a viair that connects directly to the battery (it would blow the fuse). Haven't used it on the 3 yet but it has rescued a dune buggy out in the sand 
Filled the plugged tire up decently quick too.
Filled the plugged tire up decently quick too.Thank you guys. I purchased the 70P and it just arrived. I was able to use it from the cabin 12v port. My original pump is definitely done
I must be definitely doing something wrong. The first one I bought is this one: https://www.amazon.com/gp/product/B07G96ZC5X
After plugging in and connecting the hose to the tire, I turned it on, it would come on for a micro second and then turn on. My tire was at 42 PSI, so I figured this one couldn't handle that.
Ordered a 2nd one, recommended on this thread, https://www.amazon.com/gp/product/B015VXWZ9O
Same exact behavior. Turns on for a micro second but then turns off.
Now I have ordered the VIAIR one used by others and see what happens.
Question for those that have gotten these to work, since there is no turning the car "on", what is the process? When I tried, car was parked in garage and I opened the door to wake the car up and the 12V port was powered on. Did not do anything else? Am I supposed to be doing something additional?
Thanks!

You must have a lose connection at the cig lighter port. Something is askew there for sure. I have four of these. Two Tesla and two from other sources. Sometimes the V1 Tesla gives me problems.
Your problem must be in the port for 12V. Have you tested them in other cars you have?
