In the very near future my rig will have a spare. I have not decided if it will be mounted or not. I am leaning towards a mounted spare on a carrier in the rear. It will need to be a movable mount to allow access to the engine. If you do not carry a spare you MAY be stranded for a considerable time if the dispatched service does not have a tire on hand. If they do you may be paying a lot for it. I will be adding the sockets I need to change a tire myself. I hope never to have to, but I do not want to be stranded without being able to self-rescue. I have had one blow out, it took 4 hours to get service out. And if I have been a mile or two further along, I'd have not gotten service until the next day. We were just inside a Cell Service Bubble. I am starting to consider if mounting the tire in front may not be a better idea than in the rear. Yes there is wind resistance, but no heat issues from the engine.
