Storing tires upright?
So, dedicated snows on rims for both cars (Jetta TDI Sportwagen is the other) and storing the mounted all-seasons in the garage till they can go back on when the weather gets nicer.
I can see why you wouldn't want unmounted tires to be stored laying flat in a stack- squeezing the beads together and maybe imparting some memory into the radial cords...
...But what about storing mounted tires laying flat? And maybe tossing something else on top of the stack? I am looking for more efficient use of my limited garage space here. Anyone care to explain the rationale behind stacking them upright?
...Also, should they be kept at their normal pressure or let down some?
Thanks for any help!
Best wishes,

If anything, store them with higher pressure. Mercedes says that 3 psi more than the recommended is actually their recommended for better handling. Driving them increases psi. So storing them with 5 psi more is no big deal. That would help if you stack the tires. If you don't stack, the added psi is still good. For cars that are stored, increasing the psi is recommended per another European car maker.
