Do you carry a spare tire for your Class C?

My 2014 RV did not come with a spare. I went through the hassle of finding the correct wheel rim and tire, had it mounted, and store it in my exterior storage bay. I just don't want to deal with what would ensue if I called for roadside assistance without one.
Does every RV roadside assistance service provider come prepared to remove the old tire from the rim and remount a new tire? How can they be prepared with the correct tire? I know whatever they do it ends up costing a bundle.
