Do I need to carry spare tire?

Bluwtr that the spare would work was never a question. We ordered our unit from an RV show 20 years ago this last month. A spare mounted on the rim came with it. . And as I said DH is a maintenance freak and he immediately checked that all our rims and tires where the same size. Also always checks it along with all tires that it is in good condition and air pressure is up and good before we leave on any trip long or short. We have witnessed a couple of very high end units being towed by trucks that were not suited to tow their units. They literally tore the front ends off the unit. Really would not like that to happen to us or anyone. This guy we had help us said he could not find a tire within 200 miles of Indy or Louisville. When we got back on the road headed straight to CW at Bowling Green they could do nothing to help us (Elkhart CW installed the new tires). Sent us to a couple of tire places near them but they also did not have our size available. So as a result of that one experience we are so glad we had ,and still have a mounted spare on board.
