I've heard too many stories of people who contacted road service in various parts of the country only to find that they could not get, or would not, dismount and mount tires in the field.
A friend faced this situation several weeks ago and all road service would offer to do for him was to remove the flat and damaged dual allowing him to SLOWLY creep to the nearest town where he had to wait till business hours in the morning to get his tire replaced. He probably damaged the remaining tire driving on it with the extra weight but that remains to be seen.
Some might remove the old tire and wheel, and take it to the nearest tire shop with medium to heavy duty truck tire capability, and then return to mount it on your vehicle. But, how long does that take and what cost? As in the case of my friend, what happens when the tire failure occurs after hours and "road service" does not have an appropriately sized tire available or won't do the work in the field?
I have no desire to change a tire on the road, and in fact have two emergency road service plans, but I carry a spare on the Roadmaster tire carrier to make it easier and faster for road service to get the job done for me. (BTW, my rig came with a frame mounted spare tire rack but, after having a tire & wheel stolen off of it while in an RV park, I got the Roadmaster which allows for securing it with some heavy duty locks.)
