Spare wheel indentation too small

[am99ey]

I have to renew the old tire of my spare wheel, for safety reasons. The all original one is hard as rock - after 60 years, wonder wonder. The new tire is ready to be mounted onto the pressed steel rim. Unfortunately the new tire is size 165/80 R13, as the four other ones, which is slightly wider and hardly fits into the well. Any idea or experiences how to handle this?
Store it depressed and carry a pump in the boot? Change to 155/80 R13? Modify body work? Stupidly I did not think oft this beforehand.

Ive seen people widen the wheel well for wider alloys..not for a stock wheel.
Maybe carry a pump and have the tyre at the highest pressure it can while still fitting in.. maybe add some Vaseline to the area of the face of the tyre that faces the boot to help it slide down.

How about placing it into the well un-inflated, then inflate it in place (as much as possible)? I’ve never actually used a spare tire on any car for decades now - even on even my daily drivers, and on my vintage cars it’s been forever.

Just try to get the same rolling diameter. I carry a Mutt 2 temp spare but it's different rolling diameter makes it so if a rear flat gotta put the two the same size in the rear. As a related thread most in the let's go to a Suni change up driving event don't have a good spare option and one was really surprised when told that he had to have stock lug nuts for a stock wheel, not the LAT 70 style...

Lol put Vaseline on it....
