Should you carry a spare tire?


RV Tire Safety
with RV tire expert Roger Marble

I have posted about spare tires on my blog and on various RV forums. One thing almost no one considers when shopping for a new RV is the potential need for a spare tire. After all, lights in the ceiling seem to be more important to many, as is having three televisions.

The assumption that having a “Roadside Assistance” policy is good enough many times does not work as well as the advertisement would indicate.

Competent truck tire service centers have the ability to change tires at the side of the road but it appears that the insurance companies (ones selling the idea of assistance) are really only knowledgeable about cars.

I have suggested that if you don’t have a spare you should be able to get a used tire – in your brand, type and size – and find some way to carry it around. Used tires should cost closer to $50 for 22.5 sizes, and if you know a fellow RV owner who is getting new tires I bet you can make a deal.

Having a tire only would allow a regular truck tire service truck to come out, mount, inflate and change the tire. You still will need a new tire, but you should be able to get a better price on a new tire somewhere in the next couple days when you have time to do some shopping around.

Your “old” spare tire should be thoroughly inspected but should be OK for a few hundred miles at 55 mph max on a rear dual position.

I had Good Sam Roadside but when I called them to my home to change a zipper blow out tire that occurred when I inflated a low tire, they responded that they could change a mounted spare but not install a separate tire on my rim. I was told to call a truck tire service at my own expense. They offered to tow me though. No More Good Sam Roadside for me.

I have purchased all new Sailun 17.5 H Rated Tires for my 5th Wheel on New Aluminum Rims. Over 5000 miles so far and No problems. These tires replaced the 16 inch G rated tires that came with the RV.

I just ordered a New Sailun 17.5 H Tire and had it mounted on a Steel Rim, instead of an Aluminum Rim. I didn’t want to have an aluminum rim under the RV getting splashed with all that Road Crap, like Salt when traveling. It is just a spare tire!

I’ve read your comments on dealing with larger type motorhome tires. As a past trucker and now as a senior I wouldn’t want to be changing a big tire. I have a 5th wheel and have had several tire failures in the last few years. I no longer run Towmax or any other Chinese tire. I’ve called Good Sam Roadside Assistance twice for tire replacement and neither time were they able to help me. For my 5er I carry a spare, good hydraulic jack, proper sockets, breaker bar and snipe. Without a jack you can always run the neighboring tire up on blocks which will lift the flat tire off the ground for changing.

Thanks for the comment George.
My main point is to be sure you can get the Roadside service you are paying for. If you have a tire you should be able to get it mounted by a truck service truck. BUT you can’t count on the service folks to have the right size / type / Load Range for your RV.
