I'd rather ride on a rim than stop on an interstate and attempt to change a flat nowadays..\
The last blowout I had was on my '79 C-10 Bonanza long ago,I was taking my sister home 70 miles away,got almost to the exit we had to take when I heard the truck make a weird noise,it was the tire going flat,soon as I slowed down,it blew the sidewall out..
I did pull over into the breakdown lane,got out and looked at the tire,it was the passenger side rear..was about to attempt to jack it up,but discovered my bottle jack leaked after it had tipped over behind the seat..
Then a few tractor trailers blew by me inches away, going 70+ mph,I decided to get back in the truck,and drive 2 miles on the flat, in the breakdown lane with the 4 way flashers on to our exit ..at a blazing 5 mph,while cars and trucks flew by blowing their horns..

..
I got to the exit,then went another 1/2 mile in the "wrong" direction to get to a convenience store,and I bought a quart of motor oil and filled the jack up..then changed the tire in the rear of the parking lot.
Much to my surprise the rim,a old school slotted mag,was still intact,the tire was shredded and folded up in a lumpy mess ..
I thought sure it'd be scrap..
After I put the spare on I decided to open the hood and check the oil,I figured it might need a quart,and was going to dump the oil left over from filling the jack up in the engine...and there on the passenger side fender,was the OEM jack,all bolted in place like the day it left the factory..

..completely forgot it was there..
