The tow truck arrived in 90 minutes.
After the spare wheel was installed, I started driving away. And something was making a squeaking noise and the car had a lot of drag although I was driving about 20 miles per hour.
I pulled over and got out of the car and looked at the spare tire and it was flat.
I ran back to the tow truck about 150 yards away before he headed in the opposite direction.
He could not believe it. I came back to the car and turned the car around and drove back to the truck.
I drove it up on the flat bed and we drove to the nearest gas station and pumped it up and I came home finally. It took 3 hours from the time of requesting roadside assistance.
If I had a spare in the trunk, I would have been on my way after 30 minutes.
Oh well. it is what it is. Hopefully, I will not get another flat tire for the next decade.
