Do I need to carry spare tire?

Is there a valid reason to carry the extra weight of spare tire? Will roadside assistance show up with tire mounted to wheel and then change it? There is no way I could change it myself.

Some people on here have posted that they waited till the next day for flat tire service and paid 50 percent more for a tire that did not match the other tires, that's why I wanted a motorhome with 19.5 tires so I can carry a spare and change the tire myself without being ripped off and waiting 15 hours for the service..
