Thank you for sharing those! We are fortunate to live where winter tires are not really needed, but of course a flat or worn tires are inevitable. The lift point document is very interesting given that our local tire shop of choice, Les Schwab, uses lifts with large, flat, rubbery-coated plates. These save time by not positioning specific lift points, but my guess is that using it would crush the several flat "cover things" on the bottom of the car, so we'll need to find a different solution. I'm very glad to have seen that document before needing a tire changed!
