A tire machine is life changing in a good way if you have a lot of cars you're responsible for. China is starting to make mid-market ones (simple pneumatic ones that are powered bug geared to home use rather than professional like the ~$1k electric machines) for ~$400ish that I'd take seriously if I was in the market

Once you have a tire machine you'll spend more time at the tire shop (outside business hours, lol) because their trash pile will be your best source for reasonably new used tires. They sell a lot of sets of 4 when 2 would do.
