Always carry a spare and change it as you would a car tire. A bit more difficult and awkward to change a motorhome tire but make sure you have that spare. Change the tires every five years whether you think they need it or not. You shouldn't have any problems if you do that I know your question is serious but on the lighter side >>> Last time I had a flat tire, I pulled my motorhome into one of those side-of-the-road gas stations. The attendant walks out, looks at my motorhome, looks at me, and I SWEAR he asked, Tire go flat?" I couldn't resist. I said, "Nope. I was driving around and those other three just swelled right up on me. From the net "If you are out in the middle of nowhere and have a tire problem, the road service truck may not have your tire-size available, but, they can put on your spare and get you on the way. The wisdom of carrying a spare is only realized when you need it." "Not only can new tires of the right size be hard to find, but if needed, you are basically at the mercy of the shop selling you the tire (pricewise). We don't have a spare yet, but are planning on getting one. Dealer told us we can put the spare in the compartment with the propane tank. There are rails to sit the tire on above the tank." "Try to find the right size tire in a small unfamiliar town on Top of the World highway in Alaska on a Sunday. I keep my spare even when it is old, figuring I can drive slow and careful until I can properly solve the whole problem. So cost is zero, except weight and space."

Depending on the chassis design, you may have to call road service and be prepared to pay over $100 just for the service call. Just last month had both rear passenger-side duelies blow out. Chassis was inches off the ground when I pulled over. Spare was suspended beneath the chassis like in a typical pick-up truck. No way to get spare out-from-under or get jack beneath axle! Going to re-locate spare onto back bumper this month... Road service crew had a special "airbag" they slipped beneath the crippled motorhome to lift it high enough for a normal jack.

Several camp clubs and some RV insurance policies have road sevice assistance. Well worth the price of membership when the time comes.

Change the tire.

Call a truck service center. The same people that change tires on semi's have the equipment to deal with a motorhome.

We have Good Sam road service and have never had a problem getting a flat fixed.. Good Sam calls their service provider in the area and the service provider calls you.. You can give him all your info including tire size and any problems you feel he might encounter.. Sometimes it takes a couple hours to get taken care of. But who cares? You're basically at home anyway..

Call 1-800-815-9793. 24/7/365 This is Bridgestone National Roadside Assistance number. They will give you the phone number of the closest road service dealer or truckstop...

park and keep on living.. its a motorHOME remember?

UMMM...That's what a spare tire is for. Change the flat tire with the good one.

I'd call The auto club .. that is what I pay them for ...

I downrated the question because it's terrible........Might as well have asked, what do you brush your teeth with?

We get out and change the tire. We had one explode while driving up a steep mountain road, very scary, damaged the outside of the RV a little. But it wasn't a problem to fix.
