Everyone should call their ERS and ask if they supply tires...
I did and I was surprised...AAA does not have that service..
they will only mount your spare. they will tow you to a tire shop and you can wait for it to open the next morning.
I have had AAA Rv Premier roadservice for years..Now I am with Coach-net
Coach-Net does "But" on a Sunday night you may be stuck when they just sold the last one they had.
12 volt compressors...You may make it with a 16" tire but may not
you better test it in your yard..I bought a 110 volt compressor and run the generator but only for emergencies not total flats.
If you have 19.5 or bigger "test" it I have seen a 12 volt compressor pump on a regular car tire but it was a slow process..great for bicycles though.
Let the air out of your tire and test it in your driveway.
Installing tubes in a wheel that is designed for a tubeless..
you might call your service provider .... see if they would even do that...For you that have 19.5 and bigger tires..."wow" you are tough if you are planning on breaking down that tire on the side of the road yourself.
I am old man I get tired just thinking of trying that.
My class C came with a spare..but my brother-in-law's class A did not
so we bought a new 19.5 tire and put it in a compartment making sure it is not exposed to road dirt..
After 5 years I start looking for new tires..some things get top priority.
I love r.v.ing I just try to cover the "what if's"
