To each his own, I never understood carrying a spare MH tire in this day and age. Sure I've heard stories where RSA couldn't find a tire etc, but it's pretty rare. More rarer than actually needing a tire in the first place. Consider that a spare will age the same as any of your other tires and will need replacing just as frequently. Carrying an old tire as a spare for emergencies just means you'll have twice the work as you'll still need to mount a new tire when you get where you are going. Add the weight and that RSA will still need to come out and take the bad one off and mount the spare I am questioning the efficiency. Carrying a mounted spare will be pretty heavy and eat into your CCC, and then of course you still have the herniating task of changing it if you do it yourself. Been Rving for most of my life, owned MH's for the past 10 years and have yet to ever need a tire change on the road. Knock on wood and I know it happens but that's why I have coachnet and credit cards, check my tires regularly and have a TPMS. I am pretty certain the money and hassle I have saved is far more than what I am going to spend on a blowout and tire change on the road when or if it happens. I have to imagine the reasons I stated above are why new MH's in the past 10 years no longer have spares.
But to each his own and good luck if that's your agenda. I can certainly understand being more self sufficient.
