Lifting pucks

I've got a set of these in my trunk too. Amazon.com: 1409KMT 4PCS Tesla Model 3 Jack Lift Pad Adapter Aluminum for All Tesla Model 3 - Safely Raising Vehicle - Protects Car Jack from Damaging Tesla Battery : Automotive
Used them the first and last time I rotated my tires. Very solid, did not stink (as reported by some other brands,) and very stable.

Work great. Solid Aluminum. Couldn't crush them if you tried. Not sure what the 'screw in things' are for though.

I've kept a set of these in the car for years. I use them when I swap my snow tires using a 3 ton floor jack, but I've never had a tire shop ask for them.
