My DIY 2020 Model Y LR AWD Spare Tire kit:
1) Spare tire from a 3rd Gen Nissan Murano. 18x4 steel wheel, 5x114.3mm (or 5x4.5”), and 66.1mm bore. The Stock Nissan spare tire size is T165/90R18 and has a diameter of 29.69”. My stock 255/40R20 has a diameter of 28.03”. I may have a tire shop put a T165/70R18 for a diameter of 27.09”.
2) Chevy S10 pickup or Blazer emergency scissor jack. This one has the little domed protrusion that fits the Tesla’s jacking point. I know of this jack because I was the first to test fit this jack for my Chevy Bolt which has similar jacking points (on the ChevyBolt forums).
3) Chevy S10 / Blazer tire iron with 21mm (13/16”) hex lug wrench.
I test fitted it this morning using all the hardware listed above and drove it around the block a couple of times to make sure everything works.
I only tested it as a rear wheel, as I didn’t test fit it in the front, so if I have a flat in the front, the first thing I will do is to swap the rear to the front then install the spare in the rear.
I also made a little tool to remove the center cap from my 20” wheel.
