Many people I know don't carry a spare with 19.5 or 22.5 in tires because they are too heavy to change and some would argue too dangerous to change on the side of the highway. I carry a spare with a 3/4 in breaker bar with a steel tube that will extend to 3 ft with 6 point sockets to break the lug nuts. The 19.5 in tire has gotten heavier since I bought the MH 15 years ago but I can still change it. In 100k miles of travel thankfully I have never had to change a blown tire on the hiway. I picked up a large screw crossing the Canadian border but used a tire plug kit to fix it without removing the tire. I hit a large pot hole in a paved road in Alaska and bent the steel rim on both the MH and the tow car. I was able to straighten both rims with a large hammer without leaking any air and moved the bent rim to spare when I got home.
