Get a matching fifth wheel, and another tire. Throw that space saver in the trash.
I do that on every vehicle I own.
Even my wife’s minivan.
If I have a flat, there’s no drama.
I don’t have to limp anywhere.
I can keep on driving as usual until I get the tire repaired.
I don’t have a spare tire.
I have five matching, and they all get rotated through use.
So I always know I have a good “spare” because it was just on the ground a few thousand miles ago.
I know I can trust it.
Of course, I have to explain it every time I go to the tire shop to get rotated.
“The spare goes to the right rear, everything goes counterclockwise around the car, the left rear goes to spare.”
And I have to watch them to make sure they actually do it.
