Carrying a 2nd Set of Wheels/Tires

[RandallNeighbour]

If it's dry, you can get one rear in the frunk, the fronts in the passenger seat upright, and the other rear on a blanket on top of the clamshell bungee corded to the roll bars.

You'll look like Sanford and Son, but it'll work.

The two rears in the trunk side-by-side (trunk lid open) strapped-in with a bungee, one in the frunk, and one in the passenger seat on a towel... I do it quite often when getting new tires installed.
