Should I keep my 43lb. spare-tire in the BACKSEAT or the TRUNK?

How much does your rims weigh for the whole thing to weigh over 40 pounds? I’ve looked on tirerack and the heaviest tire I’ve seen listed is like 25 pounds

If the placement of 43 pounds of anything would have a significant effect on a car’s handling, I’d think that car would be unsafe at any speed.

I’d be afraid to drive with a passenger that didn’t sit still.

That spare in the car cabin can turn into a deadly weapon in an accident or roll over.
